With all due respect to The Guy.
The NAD T773 is not capable of driving a continuous 2 ohm load. If you goto the website and click on the tab labeled a CLOSER LOOK you will notice it can handle dynamic peaks that dip to 2 ohms. However the 773 can drive a 4 ohm load with no trouble.
Yes, it would be nice to see a review of one of the NAD receivers however. Possibly one of the Rotel receivers as well.
Cheers,
