6SN7 Tube pre amp with great sound staging capabil


I am looking for a recommendation for a 6SN7 pre amp with great sound staging capabilities. Specifically, I would like a pre amp that provides well-defined, palpable images with a forward presentation and micro dynamics while keeping the tube harmonics and bloom. My goal is to keep the cost under $2,000 (used) however I am willing to spend more for the perfect fit.

My system includes Maggie 12s, AES six pacs and Quick Silver preamp.

I second the Mystere, although I own the ca21. I used to own an Aesthetix Calypso, and feel the Mystere has a wider soundstage and better deep bass. I bought the Mystere as a show demo from Upscale Audio, and it was about $2K.

That's easy: Atma-Sphere, either the MP-3 or MP-1. Forward presentation, to me, says frequency imbalance; if you're looking for a superb soundstage with dimensional images, then yes, these are tough to top.
 
I third the Mystere CA-21, which I've owned for about a year. Wonderful preamp, great build quality, beautiful sound.
