most impressive:

Avalon Isis, driven by Spectral gear, both amp, pre and cdp.

Wilson Audio Maxx2, driven by Mcintosh MC501's; a C2200, a Wadia CDP, a VPI Aries 3 tt, Jadis phonostage, and $25k worth of Kimber cable Reference between them

other Avalons, driven by Accuphase, spectral & Mcintosh

The B&W diamond signature series (you know, those really exclusive new 2 way floorstanders), driven by an Accuphase A-45 poweramp, c2810 pre, and DC801 & DP801 transport & DAC.
also with alot of kimber between them.

and my setup, of course
(there are plenty more impressive setups I've heard, but these are some of the more remarkable )

the most dissapointing: some really big Triangles, driven by an amp I can't remember. sounded muffled, dead, and without bass.

and some other things I can't remember.

Keep them spinning,
Bert.
