Have just checked this thread after some time (years probably) and surprisingly found it still alive. Interesting, it is mostly about 2000 (and 3000mk2, 5-7500) and so less on just 3000, is it because it is rare (I've been told once that it was made in just about 200 pcs?), or for what reason, I do not know.
Well, I have one for about 10 years, purchased from a friend of mine NOS/NIB, with all the original packaging (wooden 'trunk'' with straw, Ortofon crowbar :), Replicant display case, etc). Cannot compare to other x000 carts because have had no one to, but it is definitely the best MC I have ever heard, and I heard quite some vintage and new Denons (103, 300, 301), Ortofons )Kontrapunk, Cadenza.mc30, sl20), AT's (interesting btw, between ART, 09, I like 07 the most), and also some other not in my system. (Dynavectors, zyx, etc).
What I can say, well I totally agree with that old Stereophile review, especially on bass performance, a truly terrific power and control in that scope, but also very detailed mid range and a smooth highs (maybe someone would describe as somehow rolled off, I don't know, 10 years ago my ears were younger, so it was not really the issue). In brief, very, very relaxed sound with a large, meaty stage, absolutely free of any kind of constraint, fatigue or similar nervousness. Of course, a very good phono pre is desirable (luckily I have a very good solid state dual mono with about 70db gain set at 60 Ohm load, but I have a feeling that even less gain would be just fine).
Recently, in the past couple of years, I moved my attention to the very fine MM carts (i.e. Denon dl109d, Elac hsp796, at15xe, AT20ss, ADC25, Technics EPC205clii, EPC22, B&O mmc2 to name just some of them), and btw following some recommendations found here on AG (thanks!), so this old masterpiece is just exhibiting in its acrylic display aside of one of my TT's.
Cart was lightly used thru years, but unfortunately last time I have given it a listen, I miscarried the tonearm and missed the record brink (so realized :D that time has come to switch to a full auto TT's). The cantilever (of some carbon fiber+ ? mixture) is now just slightly indented on its inner side, but as I can tell, it has absolutely no impact on sound, tracking, plays exactly the same as before.
Well, since I am (sadly) a perfectionist, I would eventually pass it over to somebody not so meticulous like me :) to enjoy it to its last days. Not really an advertisement or a mandatory sale (no idea on market value), maybe also some exchange possible...whatever.
And yes, it's in Europe, so no Japan humidity :) issue.
