The Behringer A500 is a fanless amp, and a number of people are using them on their home systems, but there have been a few issues with audible harshness at certain freq's(3000khz?) on some units. Otherwise, as long as you get a good one, it would seem to be a decent amp for less than $200 US. Just not sure if I would want to go to the hassle of returning it for another unit as I would probably order from the States, might be a problem as well as $$ to exchange it(shipping).
The other Behringer units (EP1500/2500)seem to be trouble free from what I've read on other forums, and really at around $250 for the 1500 and about $300 for the 2500, they look to be somewhat of a bargain.
