AC Power Supply Optimization Service Empty AC Power Supply Optimization Service

Post by AndrewLK on Wed Jul 10, 2019 10:29 pm

HiFi system runs on AC power. It is imperative we optimize AC power supply as perfectly as possible to realize it’s full potential.

An electrical engineer by profession but HiFi is my passion. With proven experience in optimizing AC power for HiFi systems, I wish to share my knowledge for DIY enthusiasts and also offer my power supply optimization services, for a small fee, for those who requires it. My solution is suitable for mid to high-end HiFi system. I work on single phase AC supply only.

My implementation minimizes the number of contact point, fuse and ELCB while enhances contact integrity, reduces cable resistance and lowering noise, resulting in an optimized foundation for building your system.

Once optimized, you can then connect it to power distributor / power regenerator / noise filter ... etc follow by rest of the HiFi components. My design follow closely the activities stated in the PSAudio article ( which was installed in Stereophile Listening Room in 1991. The transformation in performance I experienced was very similar to what the PSAudio article described. Without it, I did not enjoy listening to my system at all.

I operate from a café name MyEspresso (address :  63 Jalan USJ 21/11, Subang Jaya) every Saturday from 1pm till 7pm. Feel free to come for a sharing session. I will go through the PSAudio article and explain the technical compromises found in many components that cause harsh and uninvolving sound. I like to meet you, talk HiFi, share and learn. Absolutely no obligation

If you wish to meet some other time, please WhatsApp's me at 012-6608497 (Andrew Teow) to schedule.

Meeting at your home is also possible for a fee of $50 where I can review your AC power supply and grounding, and recommend solution if needed. Full explanation will be given for each recommendation. Will also bring along some HiFi accessories and cables for trying (not for sales).
