The Zesto was $7500 new,  it was praised as the best sounding pre under 10k by several magazines... a clean one is a steal for what they go for used , when they pop up.  

Vincent SA 31MK, just superseded by the SA 32. Both are good. MK is class A.

Recently I was able to buy a slightly used Aesthetix Calypso for Aus $2200. It is an absolute knockout, nothing I have bought before made as much difference to the SQ. Huge soundstage, dynamic and above all totally musical.
