Hi Yiangos - I have a lot of questions. First, will you mind that you won't be hearing your music as it was intended with your channels reversed? This might make a bigger difference on classical recordings in regard to the placement of the musicians. Or am I misunderstanding, and you are swapping the + and - leads and inverting polarity?

The next thing I wonder is why you are getting better sound by hooking things up this way. Do you have a channel imbalance due to your volume control not being matched well? Is your room asymmetrical with a large open space that is cutting down on bass reinforcement or just letting music escape the room? Are the channel outputs of your amp grossly mismatched, or do you have room nodes or frequencies stacking because of the furniture or room shape? Is there a way to set up the room where swapping channels won't make a difference? Are the outputs of your speakers matched? Have you checked to see that a driver isn't cooked? Are your speaker cables and interconnects matched in length and do the left ones match the right ones electrically?

I'm glad it's not the gear (always better for the wallet.) Hopefully, it is something simple caused by an asymmetrical configuration. Closing a door can make a big difference in focus, soundstage, balance -- it'll be interesting to see what your results are. The door and its proximity to the left speaker and the "fix" being switching the left channel to the right does seem to point towards the door as a contributing factor... but, now, wouldn't the right channel info coming out of the left speaker suffer in some way after the switch?

Hola,

In addition to Jeff's sage questions, I'd suggestion more "playing."

I can't figure out a reason that right and left channel switching should improve your sound unless something is wrong with some hardware.

Other than classical music, most other types of music are not "handed."

There should be plenty of musical information that leans one way or the other - so if your configuration was music related, then you should see a variable effect from recording to recording.

This "unbalanced" sound you note is intriguing.

Time to be systematic.

I'd suggest switching speakers from side to side, but keeping the inputs otherwise the same...i.e. still have the speaker on the right receive the right sided signal. See if the effect of the channel change remains intact. See if the left channel still sounds better on the right, or if the "betterness" travels with the speaker.

Switch amplifier channels and listen in all four configurations: Speaker 1 on the left, then right, then switch amp outputs and repeat.

Try switching interconnects, too.

Anything you can switch from right to left, give it a go, one change at a time.

Keep a log of the switches you've tried and what you heard.

There shouldn't be any specific right or left handed sound. I bet there's a bad seed somewhere in your signal path.

*Be sure to check the internal wiring of your speakers, too. Room position may be disguising a driver that's wired out of phase to its "brother" and - although I can't figure out why - that channel switch would make a difference there. Maybe you have a mirror image pair and accidentally put the right one on the left, and vice versa!

Yay!
