--I have no "hiss" when i use my system. If you experience hiss(and it's not the sound source/signal cable), get a line conditioner.-
The only thing that i dont like about this receiver is the amplifiers ability to cover every portion of the frequency range. It's strong in the lows and highs but is missing something that the harman/kardon amps always seem to have. There is more definition and vibrance in the mid/high range. But this kenwood comes close!
I was debating on which stereo receiver to buy, but kenwood brought out this amp with exactly the same specs except for a .01% THD difference for the front, center, and right channels. Which is really good since its near the same price but with 5 channels and all of the other goodies.
So, get this amp, its good... and etronics has it for $240. This amp is a steal.
Compared to the "HK 3470" ~$350-400
