Reverse Phase Preamp with HT Bypass

I am considering purchase of reverse/inverted phase preamp. So, here is the situation as I understand it:

- In order to have the preamp operate properly, the phasing of my speakers need to be reversed. They are bi-wired, so the wiring of the positive (red) versus negative (black) speaker wire needs to be reversed coming from the amp on both posts.

- That means instead of red (positive) speaker wire to red (positive) post, it would now be red (positive) speaker wire to black (negative) post ... is that correct?

Issue: The way my system is set up now with pre/pro (AVR with HT and 2-channel capabilities) going into speakers "in phase" ... everything seems to be working properly. If I reverse the phase - in order to accommodate the new preamp reverse phasing - then what happens when control is returned to the AVR pre/pro via HT bypass? At that point the AVR pre/pro output load is "in phase" going into "reverse phase" speakers in the FL/FR channels of a 5.1 configuration. Will that create a phasing issue? If so, then what is a possible workaround? Please help me understand.

If you want to reverse the phase of your speakers, then your description is correct. The problem lies, is that all equipment that runs through the pre-amp’s HT bypass will now be out of phase.

If the pre-amp is just used for a turntable, you can always reverse the cartridge leads to obtain reverse phase and leave your speakers alone.

Does any of your source equipment have the option to reverse phase on either the remote or faceplate?

Brf, source equipment does not have option to reverse phase anywhere. Also, with exception of DVD/Blu-Ray player, everything will go through preamp - wireless DAC, CDP, and TT.

I am starting to re-think the pre-amp choice and consider an alternative that does not invert phase. Thanks for your input.

Can you hear the out of phase when playing a DVD/Blueray?

Most DVD movies have no phase standard as they are mixed from a host of different sources, which contain no standardization of phase.

Brf, I have not experimented with that. There is another situation that comes up. Though 2-channel is my primary listening mode, occasionally I like to put on multichannel SACD. The more I think about it, my second preamp choice makes more sense. Thanks again and happy listening!

Dont worry about PHASE ....Most all recordings are not in correct phase. If you can dial it in and it sounds good .IT is good ! dont stress about having correct phase its not a big deal at all.
