Warning...The following comment is from a self pronounced audio snob. Receivers Suck.
How can they call that tiny thing on the bottom an amplifier. Clean power still requires more than a few tiny heat sinks and some diodes. Here is a real amplifier.
Now this is a power amp...Of course 10 channels will set you back about $17,000 but Wow...That's power.
Disclaimer...I might be biased because I own the Theta Digital Dreadnaught amp all 115 pounds of this beast.
