Oh, I could be wrong for sure! Can you send me a link on said benchmarks?
ADTG did it for me, so please read his post. The only thing I might add is that in a British bench test lab (AVtech Miller Audio, link posted before) website, you can find the tests on the 43.7 lbs NAD T765 and the 39.2lbs Denon AVR-3808 of the same year. You will see that Denon did quite a bit better in the vital areas of frequency response, continuous output into 8 and 4 ohms, and most importantly, output impedance, cross talks, SN (weighted and unweighted), and distortions at 1W. The NAD did better in dynamic output into 4 and 2 ohms (much better), but only at elevated levels. In fact, at <=0.1% distortions, the Denon was still ahead in the 4 and 2 ohm load tests.
The Denon (both the AVR3805 and 3808) were tested down to 1 ohm and passed, the NAD was not tested for 1 ohm. In those tests, the two Denon passed all tests, the NAD failed 4 tests with an overall rating of "Failed".
