Very interesting as I was looking at a used 3B-ST.
I've never had any regrets about my 3B-SST. I use it with a BAT 3iX pre and Vandersteen Quatros. I loved the B-60 I had for years, and this was an upgrade of sorts. Perhaps some folks have trouble hearing beyond the pro-audio rep?
Most disappointing:
Clearaudio Aurum Beta. Nasty sounding cartridge, like fingernails on a chalkboard. Almost put me off vinyl for good. Bought it because of a Stereophile review. Well, cartridge purchases are often a crapshoot. Luckily, a Dynavector 10x5 gave me some taste of what could be done at this price level (at least before I broke the cantilever).
Rega Planar 3. This was before the 2000 upgrade. Indifferent soundstage, noisy motor, picked up lots of surface noise. I just don't get why Rega is so often recommended. The arm is pretty good, though.
Soliloquy 5.3 speakers. Sounded great in the dealers big basement listening room, and I'm sure I was influenced by their gorgeous looks. But they were too boomy in my 2nd floor apartment, and I could never get an adequate left-right balance. Traded them for Dunlavy SC-IIIs, which were bliss.
