Not criticizing the issue but the person, opinions not based on the facts but on who utters them, personal attacks, and a couple of others. I do not expect you to understand this; in fact I do not expect a whole lot from someone who still thinks in 'lesser' and 'greater' persons. And yes, this is an attack on your personal opinions.
Best regards,
Jan Didden

Joshua, as one of the two who criticize other the most here for goodness sake start using your brain to think about why it might be you hear so many unexplained oddities.
Speakers symmetrical? About which plane? ESL's may come close but anything with a cone is extremely hard to make so.

He probably meant low order distortion. This is more evidence as to how bad phono reproduction is. There is significant 2nd order going on. Think of an ellipse tracking a sine wave it does the "out" peak fine but can't quite get the bottom i.e. asymmetry.
I still love my LP's.
Is it IMD multiplication? NP's paper said something about this. Loudspeaker, LP, magnetic tape, they all produce quite some distortion in "stand alone" mode, but from the source POV, they operate open loop, they all don't have feedback which can produce IMD multiplication (unlike global feedback amp). The magnitude of IMD multiplication product can be higher than the signal itself.
I might emphasize the 'Hirata' articles published around 1980 in the AES. This test is unique in that it can measure amp problems THROUGH loudspeakers and microphones. It seems to pick the subjectively good electronics from the bad. How it does it, I have never been able to explain to myself, even with the equations in front of me. Perhaps, someone here can explain it better, once they look through Dr (professor) Hirata's explanation in his papers.
Please Scott, talk to Dick Sequerra about this. Insist on it, get beyond the polite banter that you two exchange. He will tell you better than I can tell you, IF you will try to accept what he has to say about FM distortion.
Klipsch overstated the problem in many of his examples. Ask John Meyer, if you don't believe me.

John, indeed, sometimes I work for free and I like to share my new ideas with other members of this forum. I don't need the money. Also, I can't stand it that almost every comment from you contains a sentence like: 20 years ago this, 25 years ago that, 30 years ago etc. We don't live in the past.
Cheers,
