Recommended FR 66 service

Another thumbs up for Robert of Anaolog Tube Audio, who did a great job on refurbishing and rewiring my 64S.

@chak, congrats on the 66FX and be sure to tell us the sonic difference with the 64FX. While I own both 64S and 64FX, I can’t help being interested in the 66S and 66FX, despite their insane market prices. There MUST (or should, if we leave out collector’s value) be a huge sonic benefit to justify the price differential. Is there?

@chakster that's interesting, thanks for sharing. I've read several report that the sonic difference between 64S and 66S is relatively small and not justifying the enormous price difference. So I'll stick to my 64S and be done with it.

I didn't know the 66FX was gunmetal instead of aluminium, which would explain the large sonic difference with the 64FX that you hear. I really like the 64FX though, but in the end I do prefer the 64S for my most treasured cartridges. My favorite arm however is Audiocraft AC-4400, which just happens to be made from gunmetal as well. Judging from its performance gunmetal must to be a great material for tonearms. I think the Micro Max tonearms were also made from this material. Never heard one, but by all accounts a great tonearm as well.
