preamp inverts polarity

@thom_mackris 
Atmasphere will probably take me to task on this, but I ended up debating the difference between phase and polarity with another fellow and was eventually convinced that there is a clear and technical difference. Polarity isn't time dependent whereas phase is described in degrees of angle from the polarity. A phase angle of 180 degrees isn't inverted polarity. It's a half wavelength delayed. 
My amplifier is a Pass F5. It inverts the polarity twice through two gain stages to preserve absolute polarity at it's outputs. What's more, its a myth gain stages always invert polarity. It completely depends on the mode the gain devices are operated in and it's entirely possible to get current and voltage gain from a single stage while preserving absolute polarity.

Why do you keep babbling? I know what polarity I'm working with because I've put my fingers on every single transistor. Do you want me to show you schematics and explain to you what modes every transistor is working in so you can follow along? As I explained above, phase and polarity aren't interchangeable. I wish I could remember the guy who schooled me on that one when I argued they were, but he was right.

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

Quite so. That's what I wrote:

You can decompress air it until it's a vacuum ...

Decompress is not the same as evacuate. There can be no vacuum without an enclosure. There can be compression and decompression in a room obviously, for acoustic waves, but not a vacuum. In space no one can hear you scream.

Costco, when speakers are “out of phase” I.e., the + - wires are reversed on both speakers, the system is in the Reverse Absolute Polarity from whatever state it was in previously. Polarity is relative. That’s kind of the whole point. And in that sense, as on the test track on the XLO Test CD, “out of phase” is equivalent to Absolute Polarity.

I suspect this is just a simple case of you following the wrong ...you know...🐑 🐑 🐑
