Has anybody bought and tried these Yuanjing 300W LME49810 + 5x 2sc5200/2sa1943 monoblocks yet? The Natsemi LME49810 chip is the successor to the LM4702, and has vanishingly small distortion with the right kind of output BJTs. At the moment, it's hard to beat the Toshiba 2sc5200/2sa1943 pair for overall price/performance.
New - 300W LME49810 Mono channel Audio Amplifier Board - eBay (item 230440057953 end time Feb-22-10 15:13:10 PST)
The $50 price point is fairly reasonable for these assembled monoblock boards, which include a speaker protection relay as well. Of course, if the bare board becomes available later, that could also be considered.
