@whipsaw,
Perhaps I should have been clearer in stating that no one has been able to consistently identify sonic differences between 2 level matched solid state (sand) amps.
With valve amps all bets are off, though even there it's been noticed that better measuring valve amps tend to sonically converge, not diverge, with their solid state counterparts. A straight wire with gain as Quad's Peter Walker once said. Didn't he also claim that he didn't need to listen to his amps? The measurements alone told him everything he needed to know.
And then there was the infamous Bob Carver Stereophile challenge which surely anyone with any amplifier interest should be familiar with.

Fair enough, but don't you think such a groundbreaking discovery is worthy of a public repitition?
Just imagine how many magazine editors and reviewers would come racing to plant laurels around the head of this much welcomed harbinger of glad tidings?
Of course no designer of any digital product, cable or amplifier has ever claimed or even attempted to demonstrate the sonic superiority of their product, let alone subject it to a blind listening test.
I wonder why?
So why not go ahead, and make their day if you can? I think we'd all be curious as to what exactly these so called claimed differences actually amount to.
