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!

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.
A manufarturer's choice to include polarity reversal is based on budget and the sonic dgredation involved in the extra stage that most designs would require, and that of the switch to control it.
