Preamps

VAC will do phono, sub, by bypass. I love mine. 

Another Ayre KX-R recommendation.  They are more than your target price, but you can sometimes find them on audiogon for sale.

Ricred1:  I know something about the corus and 625 amp as I owned them and should have kept them.  If I had just ponied up and bought the uber power supply I think I’d be miles ahead of trading and selling to TRY to find something better. I would beg borrow or steal to get to try that power supply in my home. I bet jeff would help if you call him directly. It’s absolutely worth the effort imho. you’d then have something very special.

4425,

I appreciate your concern. Unless I come into a lot of money I'm definitely not replacing my JR 625 S2. The verdict is still out on the Corus and it really depends on what I hear relative to the cost of changing preamps. I may hear some preamps that are different, but not worth changing from the Corus.

ricred1, 4425,

I just contacted Audio Research about your statement that the ARC preamps having issues with subwoofers, and they said there would be no problem.
Where did you get that info?
