Any issues using a preamp that inverts polarity on SDA speakers ?

If not then all you would do is reverse your speaker cables at each speaker, reverse Red and black ?

Thanks,

Is this a question or a statement.

yes-- I've done it both ways--just let your ears be your guide.

As George suggests try it both ways .Some claim absolute phase is audibly significant others not so much.

How important it is depends on what type of music you typically listen to.

If it's multi-tracked, assembled music, like just about all current music is, then absolute polarity is almost always gone and no longer a concern!

If you listen to recordings made from stereo microphone pairs, like some classical is or almost all Chesky recording are (amongst other "audiophile" labels), then you will have asymetrical information in the recording being played. At that point, then it's a matter of whether your sensative to hearing this. Some people pick up on it right away and some don't.

On a scope, you can clearly see asymetrical information as greater positive going information when the polarity is correct. This can even vary, due to flipping phase information as released from the labels. In those situations, it can be obvious on a scope that much more information goes in the negative direction.

In the case of having a polarity switch on a preamp, it can be pretty obvious as sounding more natural when you restore polarity to the correct direction. Horns like trumpet, trombone etc. are some of the greater asymetrical information that I've personally seen. Human voice also.

Personally, I'd suggest when sure that you have either preamps or amps that flip phase, I'd correct by reversing the speaker leads and then not worry too much about it otherwise.

Thanks guys. I just wanted to know if it was ok to do on SDAs and I now have my answer. Thanks again.

No issues and this is very common. Most people don't read the manual enough to notice this in the first place.

my experience is that there are some folks who can hear/detect absolute phase and some (probably most) that cannot. I suspect that it's like perfect pitch (or maybe more like synesthesia) - both of which are relatively more common in musicians than in the nonmusical schlubs (such as I).
