Correct Way to Invert Phase

According to this thread 92% of all CDs play with inverted polarity (I heard similar stats before).

@delcal  This has been debunked. The correct number is 'about 50%'.

The 92% number comes from the guy that has the most experience - The Polarity Pundit, George Louis. I do not agree or disagree with the Polarity Pundit but find the topic quite interesting. A random distribution of polarity actually doesn’t make much sense because not all recording and mastering engineers are ignorant of or don’t care about polarity. IIRC The number 92% comes from something to do with the digital manufacturing process, since vinyl is mostly in correct polarity, at least according to the Polarity Pundit.

Clark Johnsen, author of The Wood Effect, disagrees generally with the PP but I don’t recall if Clark offers a percentage of CDs in reverse polarity. When people say the correct number is 50% they’re just guessing. Making CDs is not a random process. Certainly some audio recording engineers and mastering engineers must care about polarity. So, on that basis you’d expect the percentage of CDs in correct polarity to be higher than random (50%). As Judge Judy sez, if it doesn’t make sense it’s not true.

If something is not bunk it can’t be debunked. - Old audiophile axiom 🤡

I have a Vinnie Rossi L2 preamp that inverts phase and I almost didn’t complete the purchase because of thick and slightly bloated bass and a detail imbalance... Vinnie said what most here say...but I switched phase at the speakers and I get much better / proper balance. ::shrugs:: 

Hi,

I appreciate all of the input.

It confirms the correct way to invert phase is with the speaker wires.

I will continue on that track. 

Thanks for listening,

The use of a single gain stage means that the L3A main outputs (but not the buffered tape and surround-sound outputs) invert signal polarity. Since no phase-inversion circuitry is used, be sure to reverse speaker cable polarity at either the power amp or speaker terminals in order to maintain correct absolute polarity.

Hi, 

This is for audible illusion and it is on reversed polarity and fix to reverse speaker cables.

Conrad Johnson refers to phase or polarity since they are different topics to my understanding albiet not the first time I am wrong ?

Cheers.
