I have four of them, no readily audible fan noise (perhaps a slight bit if you put your ear up to one)issue nor hiss (with 92dB sensitivity speakers, but do remember chatting with one guy with super sensitive,speakers, like 108dB, in a very quiet room had some hiss issues, but also had the same issue with a Marantz pre-pro...he ended up with Benchmark gear IIRC). Like Dan said, they've gone up in price...and I would get at least 1500s/1502s, better snr spec compared to 1000/1002 models. Mostly they're for my diy subs but have a couple extras so using two on mains again (and did for a few years before I built the subs too).
What is the particular application for you?
