I've had problems getting a receiver to work well with my NHT speakers. I have two 2.5i speakers and one AudioCenter 1 (details are here: http://www.nhthifi.com/Owners-Manuals ). I had them hooked up to an old Sony ES receiver (10 years ago, it was the top of the line Sony ES). That worked for a few years and then the heat/overload sensor in the receiver started tripping (even when the volume wasn't that loud), it became more frequent, and eventually the receiver stopped working and I was told it couldn't be repaired.
Next I tried to use a fairly cheap JVC receiver that someone gave me for free. It would run about 30 seconds before it tripped for an overload and shut down.
