Phono Pre Upgrade

I'm in the market for a new phono pre. I currently have a ASR Mini Basis Exclusive in my system. I would like to spend around $4000.00 used give or take. I am willing to entertain SS or tubes. My current system looks like this:

Audiomat Integrated
Clearaudio Avantgarde TT
Clearaudio stradavari cart
Sonus Faber Cremona speakers

Thanks in advance for any and all suggestions!

I really like the Herron VTPH-2 which new is below your price point. I can't say I've compared it to a lot of different units out there or ones that are considerably more expensive but I cannot recommend the Herron highly enough based on what it does in my system.
The Basis Exclusive is avalable used for under $4000, sometimes considerably under. I have one and I have been told by an audiophile who has had several including the current model that there is little difference in their performance. I would also suggest the Audia based on my experence with their line stage.
I second the Herron and Keith is grerat to work with.
