Not particularly. He has a thing for an earphone-esque setup. The guy who built the system uses a placement about 5 feet back from the "listening chair", which presents much more depth and soundstage. However, the setup there is still not optimal, due to the toe-in for the owner's listening chair. It still rocks though.
I do not know the drive system. The arm is a Fidelity Research 1066, with a japanese LOMC stereo cart (same company for Mono), a custom silver coiled Step-up transformer, and some other goodies. The amps are all direct coupled, and the mid/high amps were capable of using a number of different tubes. We were using "Mesh 50s" at the time. I will dig into the detail a little more.
Yes.
Not much. It was a Tribeca loft, nicely decorated but not treated for sound in any meaningful way. There are some soft panels behind the center stack, but that's about it.
Indeed.
