Naim Prefix phono stage

I have a Linn LP12 with an internal Naim Prefix phono stage, thinking of using it with my Audio Research preamp, but was told by a friend that it may not match and sound good. Can someone give me an expert advise on this before I commit to buy the external power supply to runs it.

How about trying out with a passive pre (plain audiophile rated volume pot) straight to power amp. See if you like the sound, which may be purer and more transparent. I wonder with what reasoning did your friend say its not a match.
