Totem, I will let JP comment if he sees fit, but "Bi-directional servo" was apparently mostly a marketing gimmick, used by both Victor and Yamaha. The servo on the TT101 was well designed, according to JP, but really not different from or any more "bi-directional" than that used in the SP10 Mk3, for one example.
I think I remember now why I was a bit down on the GT2000; I once saw some photos showing stress fractures in the tonearm, around the pivot point, arising from the fact that some key parts of it are actually made of plastic. But if it has a coreless motor.... Also, it appears to have a high mass platter. There's a version called the GT2000X, which sports a large apparently metal brace around the plinth. I think it was an accessory which could be purchased as an option. Anyone here know about that? The GT2000X looked hot and cool! (Both good things.)
The Sony PSX9 seems to have a built-in phono stage. Is that correct? I wondered how it would otherwise differ from a TTS8000 or 8750.
