I sold a little Cambride (England) 80WRMS/4-Ohm remote integrated, circa '02, I think around $450. It was great value, musical, easy on the ears, minimum fatigue. Setup with the RM1s (now discontinued) in a totally huge room. I could have lived with it. Let me know if you want me to check the model number.
Also the circa '00 Audio Analog Puccini totally kicks but under $1000, unbelievably musical & detailed, non-fatiguing.
Above that the Austrailian Plinius integrateds simply are wonderful (if they are still around). They beat more costly seperates and appear to be universally admired by all who hear them.
If interested am happy to look up other models. Can't remember off hand because it's been awhile. Stereophile's Recommended Components list has been a good source for a short list of amps to consider.
If you are considering $2000 you could find a tube integrated with decent power, but I'd personally prefer SS.
Happy searching!
