Which Pre/Pro gives the biggest bang for the buck?


I would like to know which HT preamp/processor provides the most performance for the money in the used market? I'm not interested in HDMI. I'm only familiar with B&K products which I understand is the Low of the High End, like the B&K REF20($200) REF30($400) REF50($600). These to me represent good bargains/performance for money. I was wondering if there is a similiar or better deal out there to be had with comparable or better performance.

Aragon Soundstage. They occasionally appear here but EBay seems to have a lot more of them.
The Holy Grail is one that was upgraded to 7.1.
Nice but not necessary.
If you'd like to go brand new, check out the upcoming Emotiva products - world-class components with most every bell and whistle. And their prices are VERY competitive. I'm grabbing a UMC-1 when they are released this Fall...

Proceed AVP - you can get one for about 900$ and it perfroms at the 4k level. It's 5.1, not 7.1, and the support is through madrigal/harmon even though the proceed brand is now defunct. It's built like a tank. I had one and sold it to upgrade to a Krell HTS 7.1.. in retrospect i'm not sure i advanced any. just got itchy...
