I have actually setup a number of these receivers and wouldn't give them too glowing of a review. They sound fine for the price, and match other Samsung components well. The lack of transcoding to HDMI is a real concern for me. Also, the lack of an audio return channel (ARC) is annoying for people using an OTA antenna hooked right to their TV.
I have had a number of problems with the receiver dropping audio. For a few clients, I have had to set their blu-ray Players to re-encode the new HD sound formats for the receiver to work properly.
Since the receiver is so lightweight I wonder if it is using a class A/B amp or a switching amp? Either way, power hasn't been a big issue for me.
Still, there is nothing that makes this receiver stand out over the other competition, other than the included iPod dock. The Denon AVR-591, for less money, has ARC, transcoding to HDMI, and a lot more setup features. The crossover on the Denon isn't global, you can set an volume limit so our kids don't crank it up too loud, and you can set a power on volume level. I am not a Denon fanboy, but their receiver at this price point is much better in my opinion.
