Purists, audiophiles, people in the even "well designed" amps all sound audibly different, would have to make their choices. Would they accept subpar SINAD (by Amir's standard) because Dirac Live more than make up for the loss there, or not? Or they hate AVRs/AVPs so much it wouldn't matter to them anyway?
As side note, I thought even purist would agree the most audible thing with amps (if they were to have their unique sound signatures), is frequency response characteristics, yet they don't seem to understand the in room response of speakers vary so much, making the little difference on the amp side mean nothing to their ears, logically speaking. Just look at the Dirac plots on that video, and anyone should be able to see my logic, but no..., my logic must be so wrong!
Below is the speaker in-room FR as heard by Dirac/Mic for different positions:
So I won't worry about the FR of amps that typically resemble a near straight line, but others may worry enough to spend thousands of dollars, go figure.., again my logic is so wrong/fraud!!
