Reversing absolute phase


Hi there,
I heard this phrase before and was wondering, what does it mean and how do you do it?

Any specifics would be appreciated.

Thanks in advance!

As one might guess, I agree completely with Eldartford and others who expressed similar sentiments. But it goes back to what I stated above: if you DO care a lot and if you CAN hear the "difference" consistently, get yourself a preamp with a phase switch, preferably on a remote control.
The Herron Audio VTSP-2 preamp has absolute phase on its remote. Attention to absolute phase via a remote is just one of the little things that add up to a great sounding system. It goes along with dressing cables, cleaning contacts regularly, running degaussing sweeps, etc. If we were normal, we wouldn't be audiophiles ;-)
The Aesthetix Calypso is another that provides this essential (to me) feature. Nice that it's also a great-sounding preamp.
Eldartford, given that hardly any manufacturer provides a way of inverting the signal, I hardly worry about polarity, but I know from much experience that one direction typically sounds better. Presently I lack any capability to change either digital or analog. It is real shame that there is so much disregard for correct polarity. If recording engineers were less lazy and music companies more concerned, such that we could know that all recordings had say the first oncoming sound as positive polarity, we could all just set our speaker leads one way and forget the problem. Alas, that is very unlikely. I am sure in the digital domain that software could just set every cut to onset positive polarity.
IMO, there may be no such thing as "correct" polarity on the recording end. There may only be such a thing as one polarity sounding better than the opposite one to a given listener at the other end of the electronic reproduction chain.
