In 2001 I bought a Conrad Johnson Sonograph SA 400 power amp (200 wpc) and SA 25 preamp, which retailed for $1800 and $1100. I recommend either or both highly; I sold them only because I moved to tubes. The $1100 125wpc SA 250 was Stereophile Class B at the time. CJ MF series power amps from that era are also in your price range.
