Phase inverted..why?


I just bought a Rogue 66 Magnum.
Its design is phase inverted.
I have to switch the polarity of the speakers cables.No big deal, but Im wondering why a product would be designed like this.

Geoffgarcia,

The Rogue66 inverts phase. So, this is 1 phase inversion.
Does the Rogue 88 invert phase?
If yes, this is the 2nd phase inversion. Hence, no need to cross speaker connections as 2 phase inversions of 180 degree brings you to 360 degrees, which is the same as zero phase inversion.

If the Rogue88 does *not* invert phase, then you have to cross speaker connections.
Hello Geoff,
Yes, like many tube preamps, the 66 is phase inverting. You should reverse the speaker wires on both channels as you state. You should also know that this is a subtle difference and many recordings are phase inverted so you
can't always have it in phase anyway. I hope this helps -- Mark

Now that I have my 66 magnum installed and have had a chance to experiment I hear no difference at all.
its difficult to hear phase problems unless you have an ear for them or test discs
Some years back reviewers were carping about absolute phase and audiophiles began to train themselves to here the difference in polarity. I couldn't hear it and I decided not to try. After all, if I couldn't hear the problem, there wasn't one.
The only phase issue I've been concerned about since is the phase relationship between my speakers and my subs.
