preamp inverts polarity

Atmasphere, after listening to your explanation I’m even more inclined to believe G Louis. Two microphones or one, doesn’t matter, or three microphones. I also believe him when he states most audiophile recordings, even such famous ones as Mercury Living Presence and RCA Living Stereo, are in Reverse Polarity. You can squawk all you like.

Another excellent knee jerk reaction by the poster boy of knee jerk reactions. It’s not necessarily the recording engineer’s fault. It could the the mastering engineer. In any case there are no standards for Polarity. Any more than there are standards for dynamic range compression, another big fault that’s not the fault of the recording engineer. If you can’t hear Polarity, which in your case I imagine is true, then you shouldn’t worry about it.

Air is a single ended medium of transmission.

It is? Exactly what do you mean by that?

You can compress it much more than you can decompress it.

You can decompress air it until it's a vacuum, so it isn't clear what you mean here.

Costco is close but no cigar. For starters air shocks in cars compress as much as they decompress. Air is a compressible fluid. Pressure, volume, temperature, whatever. Hel-loo! Second, when the system is in Reverse Polarity the speaker drivers move OUT when they should be moving back IN and visa Versace. They are 180 degrees out of phase. Follow?

Cleedsy, old bean, a vacuum is created by evacuating air from the system not by compressing it. Hel-loo!
