I'm looking for something under $3000 used, transparency, detail, and holographic imaging are my priorities. Something that adds color is not what I want, just neutral and clean.
So what might you suggest?
I suggest you stretch your budget a bit and get this:
Ayre K-1xe Preamp for sale here on Audiogon for $3,700
I've had one for several years, and have been very happy with it. (In fact, it is now the oldest major component in my system.) FYI, while the one for sale does not have the phono boards, if you ever want to upgrade your phono preamp, the internal phono boards are near reference quality. (Note: The K-1xe has been discontinued, but it remains a reference quality preamp, IMHO, and Ayre does provide service for these still.)
My two cents worth.
(FYI, I have no affiliation with the seller of the aforementioned K-1xe.)
