Well Guido, you seem to be knowledgeable on the subject. I was going by Dennis' figures of 40-100 hours based on users experiences. I have already sent them back, so I can't experiment. After 100+ hrs neither my wife nor I could tell it had made any difference whatsoever. Further listening was painful - literally. You may be correct, but compared to my sweet old B&K it was no contest.
Interesting thing is, we became so enamored with the new W4S Dac that we have at least for the time being decided the B&K is doing to job just fine. Bass - which is what I wanted improved, now IS. Every aspect of the listening experience has improved dramatically. Better soundstage (I now know what the word means!), detail, correct tonal coloring, etc, etc. I used to read that Ohms were "good speakers, but not the last word in detail'. Well mine are, now!
As for amp burn-in, if I manufactured amps, or any component, I would feel it incumbent to burn-in before shipment as long as necessary. I thought they did that. Guess some do, some don't.
I probably won't be dippin' my toe in the class D pond again anytime soon.
