Hometheater has put a review of the RX-V473 and RX-V573 receivers on their website, look at the power output numbers in the HT Labs Measures!

How can they give them a "Top picks" rating?

Several reasons could answer your question, of course they are all hypothetical. One possible reason is that these reviews can be very bias, though I will say Yamaha is not typically one of the manufacturer's that they seem to levitate toward.

Another reason is that these measurement tests, as valuable as theu may be to some of us, are very taxing on an amplifier. Much more so than any real world listening scenarios. Your never going to see a 20hz-20khz sine wave sweep in a movie or music, much less at the volume they are trying to achieve.

Another reason could be that they are actually basing their review on sonic characteristics, rather than sheer power. It doesnt take much power before things start getting loud if your using average speakers, especially considering your not driving all 7ch with the same simultaneous signal.

What i thought was interesting was that the reviewer favored ypao over the audyssey equivelent. Which of course its just one persons opinion, but its not like you see these reviewers plugging ypao like theu do some of the other rc software

Also, for the record, the Android app definitely can turn the receiver on and off when it's set to network standby mode. Maybe the reviewer didn't have that mode enabled.

The RX-v573 uses discrete amps but the power drops as you add more channels. How does this make sense?

This also seems bad/low for clean power:
Yamaha RX-V573 A/V Receiver
Five channels driven continuously into 8-ohm loads:
0.1% distortion at 20.8 watts
1% distortion at 24.9 watts
