But I guess if you only care about dB..which I'm afraid most people are just aware of.
And what did you use to measure these purported differences? Your ears? You realize that aural memory has been shown to fade after only a few seconds right? Unless you have an A/B switching device chances are you cant make a fair assessment between 2 amplifiers.
Were the tests conducted sighted? Because the human brain is incredibly easy to influence. Ever heard of the placebo effect? What about illusions? How about the test where they took a 5 dollar wine, put it in a 500 dollar bottle then put 500 dollar wine in a 5 dollar bottle and had people try to pick the best wine. Even the experts chose the cheap wine in the expensive bottle over the expensive wine in the cheap bottle. This effect doesnt only apply to wine, it applies to pretty much anything, including amplifiers.
Take a look on these forums and others, you will find people swearing
that getting a better HDMI cable improved the image(at short distances) when that is literally impossible, 1s and 0s either get to the TV or they dont. Or what about the people claiming that speaker cables made a massive improvement in sound quality, we all know thats false(at least I hope so..) yet they insist the differences are there. I dont doubt you think
you heard those differences but whether you actually
heard them is up for debate.
So chances are unless you did a blind test to remove bias while using an A/B switcher to preserve aural memory, your alleged improvements in sound quality are anything but credible. You give us no reason to take your word over the numbers which say he will probably be just fine with his AVR. I wont even get into how inaccurate of a measuring instrument the ear is in the first place.
