phase control on BAT VK pre amps

It took me years to finally hear it with any consistency. To me, it sounds like a timing issue. Either way, the difference was fairly small.

Hi, I used to have a BAT VK51SE. And I did use the phase control. I could hear it on some recordings. Especially in the tightness of the bass and openness of the soundstage. A lot of times it was just hard to tell..."

I don't know if you guys are aware of this, but with regards to absolute phase like we are talking about here, not all recordings are made the same way. About 50% are recorded in phase, and the other 50% are not. That means, regardless of what equipment you have, phase button or not, half the recording you listen to will be in phase. This is not an easy thing to here even with the best equipment. I don't know, or have heard of anyone who could reliably tell the difference between the 2 settings even when they can hear a difference. Myself included.

"My son and I both noted the exact moment of reversal, different days, no prior discussion. I own a number of recording(CDs and vinyls) that I have marked for reverse phase playback. As Ralph mentioned; there are many more in which no differences will be noticed."

Keep in mind that the Chesky CD is made for demos. Most likely, they selected tracks that emphasize whatever quality they want you to hear.

" I own a number of recording(CDs and vinyls) that I have marked for reverse phase playback."

If you can hear the differences, why mark them? Are you sure you're not dealing with psycho acoustics here? It seems likely that you wouldn't know the difference if the albums weren't pre marked for you.
