Warm integrated ss amp around 650?


I have a pair of Von Schweikert vr2100 within an HT system, that has a decent bypass to 2ch. (the vr2100 are the mains). I need a 2ch amp. for under $650 that is warm, laid back, smooth... prefer to try solid state integrated. Any suggestions (considering the used market of Audiogon.)?

YBA Integre. You may have to go up a tad more for the DT model. Hard to find used. They are that good! Pretty sweet for SS. I loved mine. peace, warren
Any of the older Classe are worth a listen. The CAP-80 and CAP-100 should be in. or close to, your price.
