Rotel RB-990BX stereo power amp.  I'm the second owner, bought in 2009.  Sounds/operates like new.  Very good condition, 7.5/10 on Audiogon's condition scale.  Compared it to several other amplifiers under under $2500 and none touched this RB-990BX.  While I don't have the original box, I have a Krell box that will work.  This, and the very similar RB-991 and RB-1080 were/are Rotel's best sounding 200 wpch stereo amplifiers.  Rotel conservatively rates the 990/991/1080 at 200 W/ch into 8 ohms and 300 W/ch into 4 ohms.  I have over a decade of 100% positive feedback and am a very fast shipper.  The shipping and insurance will cost $70 but I will pay it at my asking price.  Numerous glowing reviews of the RB990, RB991, RB1080, all very similar amplifiers...

Summing up 
The Rotel RB-990 is an exceptional performer, especially considering its modest price and generous power rating. Its resolution of detail and overall neutrality hint at a performance level that one would expect from an amp costing two or three times as much. Although one might obtain a higher level of refinement and resolution by spending up to $2000 on an amplifier in the 100–200Wpc range, I'm not sure that would necessarily be a cost-effective investment. This may be the ideal amp for those shopping for a $2000 amp, but who really wish they could find an extra thousand to invest in the front-end or speakers. The RB-990 may be just the solution.
...the modest-looking Rotel proved a powerhouse, delivering 281.5W into 8 ohms, 539W into 4 ohms, 974 W into 2 ohms, and 1615W into 1 ohm. The latter corresponds to an RMS current of 40A by the way!
