My Quicksilver preamp inverts polarity

Geoff, you yourself stated polarity of recording is about 50/50 just in the recent few weeks somewhere around here!So you should stop just grabbing whatever to create buzz. LOL(at least you stopped parroting polarity of wires, it really was getting tired)
Anyway, I am only guessing how many of my own CDs are reversed. Sometimes the sound is a little off and I flip the polarity and maybe it gets a little better. Sometimes not.Since I am listening mostly to CDs made by digitalizing old 78's (EU to steal copyright)  jazz sets from the 30's and 1940's, some 50's..Anyway the sound quality is not audiophile... But the music is great.
Like some folks watch Wizard of Oz, or Charlie Brown Christmas, I watch the PBS series Ken Burns 'Jazz' every year now. Always something interesting I just did not remember..

You’re close. Very close. I said at least 50%. Because George Louis says 92% but that’s a harder sell. Capish? But now the cat is out of the back. Fire at will. He’s got a web site where he explains his reasoning, it’s for the advanced student. But the point is that it doesn’t matter if a preamp inverts Polarity or if the system inverts Polarity for any reason since the CDs are at least 50% of the time inverted Polarity. If you cannot hear Polarity on your system you should be happy! 

Throughout my systems, I have an Adcom GDA 700 and an Audio Alchemy DDE V 3.0, and they both have phase switches. So it was known way back then that many cds were recorded out of phase ( as well as some equipment reversing phase ). Enjoy ! MrD.

I had all three iterations of the Audible Illusions Modulus 3 preamp and all of them inverted polarity, as did the Rogue RP-5 preamp.  I just switched the connections at the speaker end and left it at that.  Never bothered me.

The Atma-Sphere pre's have polarity switches, something I wish all did. My old Decca cartridges were themselves polarity-inverting, iirc---do the Quicksilver and Modulus invert in their phono stages or their line stages?
