I'm in the same search, and the Pioneer looks like a very nice unit. This bugged me, though:> 110w x 7ch MOSFET rated at all channels driven.
This is rarely, if ever the case. I'm assuming it's into 8 ohms, 7 channels would be 770W of power continuous. I went to the website and checked out the VSX-52TX, which is the Elite version. If you open the enlarged back picture you'll see, just above the speaker terminals:
"AC 120V 60Hz 480W 630VA"So it has a 480W (or 630VA when scaled for AC) power supply. Assuming the amplifiers are 100% efficient (not very likely :) where are the other 290W of continuous power coming from? Not to mention all the digital electronics probably soak up another 40 or 50W. Unless it has a *massive* bank of caps, I don't think it can sustain 110W all channels driven. Even with digital amplifiers, you'd probably need at least 1000W of available power to drive 7 channels at those power levels.
It's still a very nice receiver, just don't expect it to push 110W all day long :)
