Whoops! That line wasn't really intended to be part of the post. I was "thinking out loud" while fiddling with the "signature" option when I typed that and obviously didn't proof read carefully.Still, you may think it's an obvious tautology, but it sure doesn't seem to be obvious to many of the inmates. This thread is a classic case: a "flabbergasting" difference with no bother given to actually showing a change in the output waveform. I would simply blow it off if it was a regular inmate making the claim, but in this case it's being made by a self professed "audio engineer" who makes his living peddling kilo buck audio add-ons that supposedly deliver these same types of experiences. I think it's fair to hold audioengr's claims to a higher standard.
And what is that claim? Not that the new power supply reduced hum or distortion, but that it made a flabbergasting improvement in dynamics when using Async USB interfaces. Now to me, a flabbergasting improvement in dynamics means that the loud parts are noticeably louder and the soft parts are noticeably softer. For something to be noticeably louder, it must of necessity be louder. For something to be noticeably softer, it must of necessity be softer. In other words, audioengr is saying that changing the power supply effectively remasters all the music passing through the Async USB interfaces. That to me is an astounding discovery, and not something to just be tossed off as a casual curiosity.
Hey, I salute the man for making this breakthrough. I'm just asking that he share it with the rest of us. As I said, we can't travel to his listening room, but he's an audio engineer: how about posting some files on line to demonstrate his discovery? It should be trivial to demonstrate that the loud parts are now actually louder and soft parts are now actually softer. I suggested Audio Diffmaker, but heck, he could just post some Audacity screen shots showing the differences between the output waveforms that the new power supply caused. Wouldn't you like to see that? Isn't that the sort of thing that an audio engineer could toss off in a few minutes?
On the other hand, if the wave forms show no differences in the dynamics before and after the power supply swap, or only show trivial changes below the level of audibility, then how on earth can the changes even be audible much less flabbergasting?
Edit: My above post assumes that the signal provided with the original power supply was "correct" so that the new power supply must somehow be remixing the sound to create the flabbergasting changes. However, it may be the case that the original output was somehow defective and "incorrect" in which case the new power supply may simply be making the output "correct." However, even in this case it should be simple to demonstrate the actual changes to the output brought about by the new power supply.
