What gear do Audio manufacturers use at home?

Excellent question, I've wondered that myself? I think many times we would be surprised to see some of them use avarage equipment as opposed to exotic equipment.

I know that the owner of Teres TT's uses a Graham tonearm on his personal table. Before that he had a Triplanar.

The following is hearsay from manufacturers or their pals...
Y B Andre PURPORTEDLY uses a 1-six pre (with premium parts) & passion monos --- just to make sure matching b/ween the two lines is good enough. Supposedly he has used S-Faber, ribbon (which?), A-Physic & JM lab speakers... Cdp is his own big model.
R Gemein (Symphonic-Line) supposedly uses his own TT/ S-Line spec V. den Hull cartridge, his own ref cdp, Kraft 250A mono, on his own next to top of range speakers.
Ioacheim (sp?) of A-Physics once used (again, supposedly) Medea speakers with S-Line Kraft 400, modified S-Line pre/CAT pre, don't remember sources mentioned (if they were!)
CAT uses his own amplification (of course) and supposedly S.Yorke Zarathustra/VPI TTs, and Kraft 250A amps for ss. Speakers not mentioned.
For what rumour & gossip is worth... Cheers!

Gilbert Yeung of Blue Circle uses his own gear powering a pair of Martin Logan CLS IIz. Here is a picture of it:

Ok, this comes from David Wilson at a dealer party in Dallas a few months ago. In one room he was using Audio Research Ref pre and amps. Another room Mcintosh. Another room Nagra pre and amp. He has 8 rooms in his house with systems. He was also very high on Transparent Cables.

David also mentioned that his nat'l sales mgr is using VTL for very good sound...
