Do you have any test data on the ncore amps which shows audible harmonic distortion with complex signal input? - kuribo

Let us know what the metric is for "good sound"....nt - kuribo 14:08:46 11/13/15 (48)

Lack of the 7th harmonic is a good place to start. - Ralph 14:41:17 11/13/15 (47)

Lots of amps, ss and class d alike, have inaudible 7th harmonic distortion- some like them, some don't..nt - kuribo 14:45:31 11/13/15 (46)

You really don't seem to get the point and have been quite consistant in that regard for months now. - Ralph 13:51:26 11/14/15 (31)

I get the point just fine...You can't seem to grasp the fact that there exists a threshold of audibility - kuribo 14:21:26 11/14/15 (30)

Actually I do get that but when it comes to higher ordered harmonics - Ralph 08:29:39 11/16/15 (27)

What about "threshold of audibility" can't you understand? The ear CAN'T pick ANYTHING out that's ( T.A. - kuribo 13:03:14 11/16/15 (26)

That is actually a different topic and phenomena and I have no problem with it. - Ralph 13:25:17 11/16/15 (25)

Different? How so? You said 7th harmonic matters....I said not if it's inaudible... - kuribo 13:46:11 11/16/15 (23)

The point is that the 7th is rarely inaudible. - Ralph 14:15:27 11/16/15 (15)
