Is phase control switch a deal breaker for you?

I pretty much had to have a polarity switch; My Gallo speakers are "extremely polarity sensitive," in the words of a Gallo tech. I had been switching speaker cables to change polarity, but finally gave up and bought an Aesthetix Calypso (formerly owned a CJ Prem 17LS2) with polarity switching via the remote, and haven't regretted it. Most speakers won't even reveal polarity changes, but if you have a pair that does, a polarity switch becomes kinda important.

I have a linestage that has a remotely controlled polarity switch (Levinson Ref. No. 32) and others that do not have such a switch. I like having the ability to make a switch for near instantaneous comparison, but, not having such ability is NOT a deal breaker for me.

I find that, with a lot of recordings, switching absolute polarity has mixed results, for example, the vocals may sound better one way, but the piano now sounds oddly phasey. One can be unduly distracted by trying to find the best position (this can change from track to track on a given recording). My current linestage does not offer this ability, so, I largely ignore the issue even though I know that there is a difference.
