That is a fabulous feature. It shows those guys really do listen to music. Those track to track changes used to annoy me listening to jazz records before I had a phase reverse switch. Interestingly some of the highest rated producers, engineers, etc had albums with varying phase in some tracks. Of course then you got those cuts where phase was different between instruments! I'm going to suggest it to Spectrals Keith Johnson. Maybe it can be an upgrade to there 4000 machine, which I think I'd 'like' to own oneday.
Polarity Questions..
My Mark Levinson 390S has a feature that enables you to program and store polarity choices per track per disc... I haven't put it to the test yet and I was wondering if others have experimented with polarity changes...I suppose along the path from recording to mass distribution it would be very easy to have polarity reversed several times... and how would it affect the sound just curious
