XLR IC with ACCUPHASE int.

Thanks Al,
I have interchange the plus and minus cable speaker in the amp. and the siffernce in sound is not subtle at all.
The sound became warmer and relaxed instead of bright and edgy, the bass is better – very good.
The thing is I have an XLR cable which will be hard for me to replace.
The other source is TV which I don't necessarily care if I listen to it with some brightness.
Does listening to a source in polarity reversal can cause any damage to one of the components

Al
I have swapped the polarities in both speakers (not only one of them).
What I mean by major change – does not mean the system transferred into some thing else, but the bass became more accurate with no reduction in strength, and string and brass are not bright and edgy.
I do have a powered sub woofer, but only using it with the HT, not for stereo, and it is connected to a HT receiver, which operates the sub and the Accuphase to power the front speakers in home theater only.
For what I understand, I can either listen to home theater in reversal polarity or swap the speakers cables back when using the home theater.
Any other idea.

Thanks you

Yes, the sub has a phase reversal switch. and I will check this issue when I get to watch a movie :)

I saw many posts which say the same as Almarg:

" I would expect those effects to be either very subtle or non-existent in most cases."

In my system the effect of inverting polarities is considerable in the bass region and the overall sound is warmer for the better.

Jacksonkuo, as I understand using the phase invert in your pre should do the work.
Could you give your impression on the effect in your system when inverting the phase?
