High resolution digital is dead. The best DAC's killed it.

Switches are nice.

Having a L to R phase mismatch is not what we are talking about. 
I'm just saying that if the perceived quality of audio reproduction could be improved so dramatically by inverting the polarity of playback it would be a common feature.

I have to believe that the lack of sensitivity to this means most of us don't have a lot of value for it.

“I'm just saying that if the perceived quality of audio reproduction could be improved so dramatically by inverting the polarity of playback it would be a common feature.”

Nobody said the sound is improved dramatically. Give me a break. It’s more like a subtle but powerful difference at best. It depends on the recording and the system and the listeners skill at hearing. Why would it be a common feature? The industry doesn’t believe in Polarity, power cords, fuses or wire directionality. So what else is new?

... no one has it because almost no one finds any value in it.

Every Audio Research preamp I've ever seen has a phase inversion function. It can be very useful!

The old McIntosh MX-100 tuner-preamp also had this function, although I don't know if it's included on more recent Mac products.
