I dont think this is a re-post, but forgive me if it is. I got the latest S&V in the mail today & noticed they reviewed the DA4ES. I was curious how it tested, because i used to have a DA5ES & the 2 are pretty similar. I go to the5 channels driven test it says N/A & to read the note below. The note says "the 5 channel test could not be taken because Sony told them that the receiver was not designed to deliver full power to all channels simultaneously. rather it was designed to exceed the EIA/CEA amplifier specification 490-A, in which each channel is tested individually at full power while all other channels run at 1/8 rated power" Does that mean Sony would not let S&V do the test or did S&V get such a bad test reading on all channels driven that they left it out? What other receiver companies rate their products with the 490-A specification?
