If you want it to not likely fail, get something
-Made in North America or Japan
-Separates
-With good heatsinking
-with minimum features at the price point.
So maybe these amps:
ATI AT2005 Five Channel x 200 Watt Amplifier - B-Stock (120 V) - Amplifiers
As for a processor, it is what it is. You really have to accept that the circuitry is too complex to have no chance of failure. I recommend this:
Marantz AV7005
Is the above cheap?
No. You're looking at 5 to 7 channels of amplification and a heavy amount of (often useful) features. If it's outside of your budget then you just have to accept that failure is a possibility, and take the gamble. I have had an SR6003 for a while now and no indication of failure, although it does run warmer than I'd like it to.
