Re: Krell - discussion thread

[mugenfoo]

who's worked up ? ... This is soooo much fun. Really.

"technical opponent" ?? Ouch ... thats too much flattery (or patronage, depending how one wants to look at it).

I actually don't know jack squat about anything. Really.
There u have it: self admission --> I don't know crap.

And then there are some who take it so seriously...

Now that's an achievement! hahaha

[mugenfoo]

No doubt that by changing the fuse will be further improve the sound quality of any equipments use. Think of 230-240v going through a RM1-2 fuse then only to the transfromer inside and as compare to the price of your value component, that's nothing.

A good fuse like the Furutech as what i am using now for my amp, CDP & buffer, it really shape up the staging & improve on the clarity & tighter bass too.

Try to replace a better fuse as the last tweek if you have nothing else to play with. It's also the cheapest tweek to play with too.

Oh cool ... where to buy these "Furutech" fuses ? Are they made of any special material compared to normal fuses ?

Are they for the 13A plugs only, or do they come in other shapes & sizes like for the Amp's output stages ?

[kowtim]

Hi Mugen

I for one believe I could learn quite a few things from you...

Regards

[WongKN]

Kautim,

Let me give you an example. Very early on in this thread, you posted about the possibility of children playing around the amps and getting injured and things like that. That raised a lot of discussion, sarcastic humour, etc, all in the name of discussion, sharing experience/knowledge, and yes, even a bit of fun as well. There were no outright attempt to 'hammer' you (using your phrase). Why, because you cited valid facts and you also cited a real-life experience about how a child carelessly dropped a coin into a Krell power amp which proceeded to short-circuit it. I.e. you provide real life annecdotes backing up some of your points.

Then later on, someone posted how amps like Krell, ML, etc "sucks in non-aircond room". He finished it by saying he doubts for 'its reliability'. From the responses that followed, I would think this statement was clearly contrary to the real life experiences of a number of owners. So they politely call on him to elaborate. Unfortunately the response was simply :

"Haha Mugenfoo.. I am repairing Hifi gears for years, the quote is based on experience rather than comment. Reliability wise, you can ask Krell / ML user on the repair record.. gud luck man.. "

So, now, isn't it valid for owners to ask for details of the 'experience' being referred to ? In fact, if you say that other forumers wants to know or learn or whatever, wouldn't they too want to learn more about the 'experience' ? Owners have already gone on record giving their real-life experience which contradicts the statement. So now, fair and open-minded people - and fortunate people who might have the financial resources and are considering maybe a new Krell integrated or a used KSA-300S, wouldn't they also desperately want details of this 'experience' which shows that they suck in non-air-cond rooms, and that a repair-man with 'years of experience' doubts their 'reliability' ?

Now, this has nothing to do with the original poster (the repair-man) but rather, I feel that for this forum and this community to grow, we should set high standards amongst us. So we share actual real-life experience : hearing, owning, and actual buying/selling experience. The whole idea is about sharing the experience. In this sense, the objective is not to discourage people from saying their opinion, but that should they have anything good or bad to say (both equally), it would be good to back it up so that it becomes an intelligent discussion. Flame wars always starts from baseless proclaimations.

One final note : again, those owners who posted against the claim that Krell for e.g. 'sucks in non aircond room', they actually fully backed up their claims with real-life experience. E.g. bimmerman's excellent post. Similarly, when you posted about the possible ptifalls of using such amps where young children can get easy access, you too backed it up with logical and valid points, and also a real-life experience. This is what I am suggesting (note jokes and talk-cock are exmpted of course, those are all for fun and I am all for having a bit of senseless fun in this overly serious world of ours).

[mugenfoo]

Anyways ... so .. where can buy Furutech Fuses ?

[chua55]

Can I know more about this tuning fuse and how can we explain its works in Krell (with 120,000uF reserve ). The next I come to know is bumble bee. wrong spelling ??

[mugenfoo]

Whats this "bumble bee" ? Another type of audiophile fuse ?

[car o scope]

Anyways ... so .. where can buy Furutech Fuses ?

Want to buy Furutech fuses??

From their website, the distributor is

I also came across an article where Center Circle Audio is selling Furutech products too.

[andrelly]

Hi fellas, I have a 2nd generation (Korea remote) Krell KAV-300i amplifier. I would need help if anyone can post or email me a close up picture of the power supply board inside the amp. I would like to compare the jumpers on this board (J1 to J12?). my email would be andrelly at hotmail dot com.
Regards....Andre

[andrelly]

What affects reliability:
1. When you use the amp to drive difficult loads, all the parts would be 'stressed', transformer, capacitors, transistors
2. When you shorted the + and - speaker terminals....
3. When you drive the amp to clip.
Heat is the enemy as overheating will kill the amp.
All these applies to any amps.....

Regarding accidents: they do occur, from children to seasoned adult experts...I know one expert tube designer was electrocuted when fiddling with a tube amp and died, could be of heart attack.
Cheers..

[WongKN]

Note to those interested in Furutech. They have a room in the KLAV show currently running in Marriott hotel. The 'super fuses' are available there. They actually come in a display case with just the tiny fuse stored in a custom foam insert. Just so you know to expect to be shocked at the cost (won't be Jalan Pasar type prices). But people who have used them swears by their effectiveness.

Hey Moogenphoo,

My Krell originally comes with Bussman AG fuses (AF for silver?) and I tried the Furutech fuse and noticed tighter, more extended bass with slightly cleaner highs. I then swapped the Furutech for another unnamed fuse going for half the price of the Furutech and behold, the midranged warmed up while gaining sharper focus, highs cleaned up and lost all hints of grain and suddenly my junior Krell was a major league player. Let me put it this way. Today i visited the AV show, heard what the exhibitors had to offer and just longed to go home and turn on my system. I kid you not. And I'm told I can expect things to get better after a 50 hour run in. I am sceptical when it comes to this sort of thing but hearing is believing. The is no name or manufacturer inscribed on the fuse apart from a direction marker (yes it's directional) So I'm just going to refer to this as the Voodoo fuse.

If you want to get the Voodoo fuse, please let me know and i'll give you my sifus contact. Just specify the ampere rating you need. 5 amps should be fine for the KAV-300i. As for sizes, he also has the speaker output protection fuses in 30mm. But I only changed the main power fuse because the Bussman speaker fuses on the Krell did not have an ampere rating. It just has a 32V marking on it for whatever it means. I don't want to risk blowing the proprietry transistors of my Krell so I left that alone.

By the way, my Cary CD300 player also benefited from the Voodoo fuse plenty! The biggest improvement in sound since I Telefunkened it 2 years ago.

Interestd? Lemme know.

[mugenfoo]

errr.. where did u use the Furutech ?

is the fuse for the KAV-300i's output stages, or was it for the AC power plug ?

[bimmerman]

Read my previous post carefully dude. It contains hundreds of thousands of ringgit worth of sonic upgrades which costs less than a hundred. Your 300i will be transformed into a Krell FBI. Maybe not, but you get the drift. You can thank me later.

Listen, I ditched the Furutech for an unnamed tuner fuse. It's the 4A BussmanAG fuse near the IEC socket of your 300i. I swapped it for a 5A unnamed tuner fuse which I call the Voodoo.

Oh, and if your UK 3 pin plug has a 13 amp fuse (they all do), forget about replacing it. Just remove the 13amp and solder the live wire to the naked fuse holder. Why do you need so many fuses? Your equiptment are all fused already innit? The Brits are far too conservative.

Or better still swap the UK plug for a US plug. Yes it's Voodoo but once i've heard it I cannot deny it's real. It's real dammit!!!

[bimmerman]

Ok, this is my last post for tonight. My music calls out to me and I cannot resist it's voodoo. Not even Megan Fox in a bunny suit can distract me from my music tonight. Hmmm... Megan. Ok, I'm exagerrating on this one...

WOW !!! the KAV-300i will Transform into a FBI !!! That TUNER FUSE must be worth at least (price of FBI minus price of KAV) RM 15,000.00 !!!! Maybe not ? ... ok, discount 90% down to: RM 1,500.00 !! Still WOW !!

hahahahahahahahahahahahahahahahahahahaha

[mugenfoo]

u wanna change the input voltage settings or something ?

[chua55]

My spelling like to get missed up with Transformer. It is Bybee the quantum purifier by our Jack bybee, the theoretical physicist specialising in quantum mechanic and superconductivity. just another cosmetic products.

Don't need to go there Wong, there is a shop where you can bargain for lower price than aforesaid dealer : Desa Home main branch.
It is a Furutech dealer.

Folks

My teacher used to tell me....A little knowledge is a dangerous thing.

The danger here is that, whilst these decisions taken by bimmerman "may" work in the context of his particular amp and the environment in which his equipment is used in, others reading this may assume that this is OK to do so with other equipment in their own environment.

Replacing fuses with higher rated ones, removing the mains fuse and eliminating any fusing there, and replacing an earthed UK plug for a non earthed US plug can significantly raise the risk of damage to your equipment, and can render equipment unsafe to be used in the wrong circumstances.

And so folks, you are free to do as you wish. Just be mindful that there are reasons why there is a 13 amp fuse in the mains plug, there are reasons why the manufacturer settles on an X amp rated fuse inside their gear, and there is a reason why we have an earth pin on our mains plugs. If you do not understand completely what you are doing, deviating from these specifications, may result in fire and possibly the death of your loved ones from electrocution.

And so, before further sarcastic comments come my way by "someone", one poster has already related that a tube accident had dire consequences for a skilled person. The swede's even back in the days of new Quad 11's refused to allow it to be sold there unless it had a cage on it. How then can one here reasonably expect ones kids and family to understand the very real unvisible dangers electricity can pose?

My advice is for those of you who want to explore Bimmermans approach and head down his path is to bring in a qualified technician in to see if some middle ground between conservative safety margins and sonics can be achieved without jeopardizing the safety of your loved ones..

Regards

[andrelly]

Yes sir! I want to know if it can be configured for 220, 230 or 240V. I was told that tp get the best performance, it has to operate at the EXACT match with line voltage, not over, not under........
Cheers!

[bimmerman]

Mr Kowtim is wise. A little knowledge is indeed dangerous. This is why I think it is better for me to issue a little disclaimer on my previous posts regarding fuses. I was high on the music and have since sobered from the mind bending musical experience.

Electricity is a dangerous!!! Fuses are there to protect you and your equiptment and bypassing fuses or replacing fuses with those of higher ampere ratings can lead to short circuits followed by fires and may result in death. Do not replace 3 pin plugs with 2 pin plugs as the 3rd pin is the ground wire. Bypassing the ground on equiptment which require grounding can be disasterous. DO NOT PLAY WITH FIRE UNLESS YOU KNOW WHAT YOU'RE DOING!!! BE WARNED!!!

Ok, now for those who understand electricity and electronics, this is what i've done so far for the record:

I've not done much actually. Just 3 things.

1. Replaced the main power 4A fuse of my 300i for a 5A because a 4A is not available.

2. Replaced my CD player 0.5A fuse with a 1A fuse because a 0.5A is not available.

3. Removed the 13A fuse of the UK plug which feeds my power strip and soldered the live wire direct to the fuse holder. My equiptment are protected by their own fuses while the power strip is protected by the household ELCB (electronic circuit breaker).

Did not change any 3 pin to 2 pin or mod the amp or anything like that. Just 3 simple things.

[mugenfoo]

for safety, if yours is already a 240V version, just leave it alone.

If yours is a European model and want it bumped up to take 240V, different story.


Better for it to be config'ed at 240, and let the home supply vary abit. Anyways, Pakcik TNB sometimes can supply as high as 255V depending on where u live, time of day, weather, which scandal of the month is in the newspaper, etc etc etc.

If u wanna mess around with the voltage to say 220v... and suddenly there is 250V coming from the wall .... Amen.

Unless you wanna plug a permanent voltmeter to the wall and each time before u listen, u gonna check the needle, and set the jumpers ... OUCH .. what a painful routine !!
Just enjoy the music from the Krell dude.

Krell designs in general employ heavy regulation for all its power stages. so it would be recommended to leave some safety margin at the AC settings.

U want better sound ?
Suggestion: Get a bigger, badder-ass Krell.

BTW, yes, i have >10 years of "owner experience" with the Krell KAV-300i in case anyone is wondering if I am just making this shit up as I go along.

Everything else, see my previous disclaimer: I don't know crap.

[mugenfoo]

help help !
i can't find the fuse on my other krell !!

hang on a minute!!! It's written in the manual that its got NO FUSES !!

It's a FUSE-LESS Krell !!!!!

hahahahahahahahahahahahahaha

[bimmerman]

No kidding Senor Mugento! No fuse? Yikes! What sort of bad-ass (bad-arse if you use the UK plug) Krell is that?

[mugenfoo]

i dunno lah .... Mr. Daniel D'agostino designed it this way ... i just use only lor.....

[bimmerman]

Hey Moogento, I do apologise for making the remark about my 300i transforming into a FBI. It's Megan's fault, she did that transformer $h1t on me and got me high on the music and I was hearing things. Allow me to add a disclaimer to all my posts. "I don't know jack"

[mugenfoo]

thats why lah ... u kena CON already...

Didn't you know ???? Megan Fox is actually a man !
Say hello to the old "Mitchell Fox".

http://weeklyworldnews.com/celebs/4783/megan-fox-is-a-man/

hahahahahahahahahahahahahahahahahahahaha

[bimmerman]

Darn!!! That explains the pain in the ass (arse if you're using the UK plug). First it was Brooke Shields, now Megan too? What's next, Mugen is a woman???

Hey, jokes aside, would be cool if I could come listen to your bad ass (arse) Krell some time. You could come listen to mine too. That fuse thingy has got to be heard to believe.

As always... I donno Jack!!!

[andrelly]

Well, I am sort of the tweaker type. I usually open up the equipment, put some damping material into the chassis, ERS cloth, change fuses ala Bimmerman's, sometimes replacing PS capacitors to better ones, replace internal critical path wiring etc......even if I get the badder arse krell, I would still open it up and do something to it to get the MAX out of its performance.....then I can sit down and enjoy....

[kowtim]

Mr Kowtim is wise

Hi Bimmerman. No. I'm not wise. Far from it. I continue to make plenty of mistakes all the time. Trust me on this one !! But, I try and learn from them.

Your last reply enables me to expand on another point that may be useful to others, Bimmerman. Folks need to be also made aware of something else. I have come across instances where the house was not earthed!

A house should have an earth rod just outside it. All the earth points inside the house should ultimately be connected to this earth rod. In the last two places I have stayed... the earth wire was NOT connected to the earth rod. Di sini, Malaysia Boleh.


I have rented a shoplot where quite a few electrical things were not working and needed to be replaced. In it I came across circuit breakers that did not trip when they should have tripped. The thing is, I was the very first tenant.

And so....as there have been so many reported instances where a dedicated mains line for ones hifi system brings worthwhile improvements, then I would say that if there are people reading this who wish to experiment with the electrical mains aspect of their hifi system.... it would be a good idea to call in someone who knows about these things... get installed a dedicated line for your hifi gear, and at the same time, check on the integrity of the home earthing, the elcb and the circuit breakers. If any of these are questionable in terms of operation or quality... get it fixed.

Regards

[kowtim]

. This is what I am suggesting (note jokes and talk-cock are exmpted of course, those are all for fun and I am all for having a bit of senseless fun in this overly serious world of ours).

Hi Wong

Im going to keep this "get out of jail" card for the time when I really get myself in trouble here !!

Regards


P.S. I always remember this funny story I heard on the news here many years ago. When the Euro first came out, there was this guy who eventually got arrested. As many people had never seen the Euro, he took advantage of this and started going around and actually paying for things with Monopoly money!!

[bimmerman]

You scare me Senor Mario Andrelly. Modding a badass (badarse) Krell. One spends a fortune on a big bad Krell to get the Krell signature sound. Modding a big bad Krell will certainly alter it's sonic character. For better or for worse, it will cease to be a Krell. A mongrell of a Krell if you will.

Consider instead to work outside your Krell, on your electrical power supply for instance. Generate your own AC if you can afford it. Find a better way to get max current into your Krell like power cables, better wall socket receptacles, power distributor, etc. and the sonic dividens will be hard to ignore. This will help you extract the best from your Krell instead or alter it's Krellian pedigree.

Please reconsider...

[bimmerman]

Good advice from Mr. Kowtim on proper grounding. Made me run around my house looking for the grounding rod. Yup, it's there 3 stories down. Phew!

Yes, i've heard stories where a dedicated 3rd phase of electrical supply solely for the Hifi setup transforming the listening experience. But i've also heard about the sound being a roller coaster ride of good and bad depending on time of day. It seems that the AC supply is polluted by noise generating equiptment in the vacinity.

I'd forgo the 3rd phase and spend the money on an AC regeneration system like those from PS audio. But I can ill afford these so i'm currently (no pun intended) using a wall receptable plug-in "parellel noise filter" that claims to clean up the AC waveform. Whatever the claim, as I don't have an oscilloscope to confirm, I can hear the difference that clean current provides and can testify that this has played a major part in my system upgrade. So much so that I was not left wanting after listening to the mega systems on offer at the KL AV Fest!

Nope, i was not moved by the Mark Levinson and the ATC, nor the Ongaku or the Gakku on, not even the new fangled Sonus fabers with exorbitant price tags. Yes, some punched harder, lower, others sang louder, sharper, sweeter, whatever... But none sang to me like my humble budget setup! To each his own but to me, my quest ends here... For this year at least.



Bimmerman out!

[BrAvO]

Furutech fuses & all other products can be found at AudioMatic, Amcorp Mall. Look for Eugene.

Furutech products are good.

[tycham]

Fuse blow!! Oh God forbid. Mine is a very expensive silver/gold fuse. Can't afford to blow that! My audio system is always unplugged off the wall socket when not in use.

Best to unplug when not in use, especially when thunder and lightning are present. Sometime the fuses might not help. My office computer even had te power pack burnt together with the fuse.

Furutech fuses are every expensive. Isoclean and HiFI Tuning might be cheaper and better in performance as test results have shown these to be power conditioner as well.

Have not found any review or test report on Furutech fuses. Furutech makes excellent connectors but they are very expensive, like it cost SGD275 alone for a pair of their CF202(R) banana plugs and normally for speaker cables you would need at least 4 pairs.

Good advice from Mr. Kowtim on proper grounding. Made me run around my house looking for the grounding rod. Yup, it's there 3 stories down. Phew!

Hi Bimmerman

More for the benefit of other folks and some useful knowledge, to complete the picture, even if there was an earth rod, and it was connected to the earth wire/s that lead to all the earth points in ones home much like in your home, the earth rod may still not be offering the protection it was intended to.

The only way that the average homeowner can know that their homes electrical grounding system is truly functional is by asking it to be checked by someone suitably qualified.

The variation in different earthing qualities from non existent to good from home to home exists due to the soil conditions that the earth rod is placed in. A meter exists to verify the quality of the grounding system. If it is found insufficient, additional rods need to be placed to either extend the exisiting one, or to add extra ones.

Interesting, your comments about a dedicated phase. It would seem logical then to assume that some phases may indeed sound better than others. It would depend on I guess which phase ones immediate neighbours have chosen to connect their air conds and whatever else noisy things to. Would be interesting to compare the difference between them.

But for those of us who have single phase, sadly no choice to be made

By dedicated mains line, I was referring more to physically creating an isolated spur from ones distribution box direct to ones hifi system using new suitably gauged wires and high quality electrical gear and even a new earth rod, not so much from the point of view of cordoning off one phase.

I really thought the SIM audio German Physics setup was fabulous on the drum track I heard. I wish I had heard voice on it now that I think about it. I can easily see why you prefer your system Bimmerman. For some reason, I think the general level of sound quality from room to room seems to have taken a step back from last years show. Purely a subjective comment...

Regards

[bimmerman]

I am on single phase and I don't even have a direct from box wiring to my listening room. But that plug in parallel filter I mentioned. It does a great job of cleaning up noise. It's made by Harmonix and I can testify that it works as advertised. Works great with digital sources.

I don't know but it seemed as if there was just something wrong with this year's setup. Why did they toe-in their speakers so much?

Yeah, the hulking German Physics omnidirectional sound behemoth!!! Yes, it was impressive and it did leave an impression. I jokingly made a comment to a friend that the sound was stunning but after a hard days work I don't want to come home to a dozen kung-fu men running around my living room, beating on drums and shouting kung-fooey at me, adding to the stress of the work day.

My quick witted friend then replied: Don't worry dude, If you return home after a hard days work, then you can't afford such a system. People who can afford this don't need to work.

Another system that left a good impression was the room with the vintage looking Tannoys. Nice and warm presentation with sweet midrange dripping with honey. Very similar to home.

[azri]

yeah vintage tannoys rocks!!

[andrelly]

Ha ha ha...done all that already.......dedicated line for audio, power cables, electrical sockets, shakti stones etc. etc.....What I am changing is not in the signal amplification circuit (eg power supply section) and also mainly passive in nature (damping, ers cloth, wires...), hence not likely to change the sound character of the Krell.........as I say...squeeze it to the max!

[bimmerman]

Ok Senore Andrelli, before you go further, get some Telos RCA caps in Gold and Platinum from the KL AV Fest and cap your unused RCA jacks. Gold for warmth and Platinum for detail. The results will surprise you!

[mugenfoo]

Darn!!! That explains the pain in the ass (arse if you're using the UK plug). First it was Brooke Shields, now Megan too? What's next, Mugen is a woman???

Hey, jokes aside, would be cool if I could come listen to your bad ass (arse) Krell some time. You could come listen to mine too. That fuse thingy has got to be heard to believe.

As always... I donno Jack!!!

^^^^^^^^^ copycat !!!

[kowtim]

Another system that left a good impression was the room with the vintage looking Tannoys. Nice and warm presentation with sweet midrange dripping with honey. Very similar to home.

Hi Bimmerman

I missed that. Were these dual concentric Tannoys they were displaying? Do you recall the model? If they are a DC's, I would love to go back and listen to them. I am a big fan of 15" monitor golds.

Regards

[andrelly]

Wow! I had been using rubber Iego caps and generic gold-plated brass rca caps. Mainly for cosmetics issue, didn't think they could make a sonic contribution......the Telos caps used have shorting plugs or without?
unfortunately I won't be able to go KLAV as I am in Jakarta...

[bimmerman]

Hi Bruce Willis,

I'm not sure. I think it was the Tannoy Autograph. Sure looked like it. I was so engrossed in the music that I forgot to ask what model they were. Curiously, they had the speaker grills on for whatever reason. Still it sounded good through those plush carpet like grills! If you do visit the show again, kindly let us know if it's the Autograph or something else.

But they definately had the Autograph Mini going for around RM6K. I always liked dual concentric Tannoys myself and I have a pair of Tannoy 609 in my collection. The 609 is not a classic and not particularly good sounding but it was the only DC Tannoy I could afford back in the 1980s. I was actually thinking of removing the 8" DC drivers and building a miniature Wesminster looking box for it but the idea never did take off. Probably not worth it.

[bimmerman]

Jakarta? quick, grab a cheap flight over here. Today is the last day!!

The Telos RCA caps are non shorting, made of copper and plated with gold or platinum (2 types). The XLR caps have 1 pin for Pin 1.

I'm still dumbfounded by how they can do anything to the sound but the results speak for themselves. The Gold is less potent than the Platinum. I use 2 XLR Gold caps, 2 pairs Gold RCA and 1 pair platinum RCA for my KAV-300i. The platinums are very potent so you can't use too many of them but then again your taste may vary. You have to try them out for yourself before you go perform major surgery on your Krell.

[andrelly]

bimmerman, is the difference bigger with fuse replacement or rca caps?
Of all the tweaks, I have not tried power regeneration......the costs would exceed my equipments......

[bimmerman]

Well, it's garbage in, garbage out so you'll have to start with the AC youre feeding your eqiptment. I did the fuse upgrade last but really should have done it first. That way you get the fundementals correct first before you proceed to tune your sound with Telos caps.

The Gold Telos caps allowed me to darken the sound canvas considerabally. Too dark a canvas and your music cannot breathe so I settled for 3 pairs. (1 pair XLR, 2 pairs RCA) I then added the platinum to improve the imaging.

I gave up trying to figure out how in the heck it does what it does but instead just enjoy the music. I have friends who plug up all their unused RCA jacks with platinum but their tastes and source equiptment are different from mine and mine is not the same as yours so your mileage may vary.

Good luck experimenting!

[bimmerman]

Oh, forgot about the fuse upgrade, Well it tightened up the bass further and cleaned up the treble. Mids took on a EL34 like quality in sweetness and fluidity.
