I need your help. I have an ARC Ref 3, ARC 110, Vandersteen 5As, but no turntable.

Ralph, sure.
$12k for five components..
Tough, very tough.

One more thing. Tonearm cable. It is the most important cable in the chain, again don't save on it and don't rush with the choice.

Ralph, I hope you are wrong about your turntable's imminent defeat. Don't surrender easily.
It is difficult to choose a turntable, difficult to audition in the same or at least similar system. Difficult to advise too, that's why I didn't really.
The idea of having both belt drive and direct drive turntables appeals to me. At least the OP should I think listen to that Technics and a few belt drive tables. The choice might also depend on the kind of music he mostly listens to. DO NOT save couple of thousands on turntable, or even more, if you do you might spoil everything.

Pear Audio turntables/tonearms deserve consideration as well. Point is that turntables of the same level do not sound identical at all. We all have preferences. Judging by your choice of speakers and electronics, your taste is not far from mine. I prefer Nottingham/Pear Audio to colder sounding even if slightly higher resolving turntables, in other words on warmer and a little darker side of neutral. All good British tables are dynamic enough.

If I remember right, Fremer has Ypsilon tube phono stage, his favorite phono stage. Unless this has changed.
Yeah, that Continuum must be something, but he compared the Technics with other tables too.

We don't know why go and I don't think that's our business unless asked for this specific advice. But if one goes and has the funds - don't save a few thousands on equipment and records. Original pressings in good condition are often not inexpensive, classical is usually less.

Michael Fremer does not like this Technics much, though he didn't exactly call it a stupid turntable. That's the common problem with direct drive turntables.

Ralph always says direct drive Technics, that's his preference, which is fine. But there are other turntables, you must audition. Simon Yorke, SME and Nottingham are worth listening to. Or maybe you can get Walker, we don't know. Generally speaking, spend at least twice as much on phono stage than on cartridge.
