I have a Denon 3803. If I use AVIA to set the levels of all speakers to 75db, the levels read by the meter are not the same using the Denon's test tones. Whilst I know that the AVIA disc contains many reference tones, I am referring to the basic white noise tones. What happens is the levels for one channel might be up to 4db different compared to another channel when using the Denon's tones. I am using AVIA and the amp is, of course, set to process it in DD. Has anyone else seen this before?
