Hi Lumba.
This is my answer:

More theoretically, along with the concept of aspect as such, where a specific convulsive load is executed (twice), while contextualizing an autonomous code infiltration of sporadic turbulence into being, striking the laterally interior portion of the vertically peripheral zone, manifesting themselves as smoke particles, distinguishing core-criteria from academic affectation.

I must apologize to you. At first I thought you were being unreasonable but it was I being species-ist. Also, I am very impressed that you, as a porpoise, have learned to type.Telstar said:

Steve Miller got into pig farming around the time of that album, the dressed-up lyrics of that song might be somewhat dubious as well.
(at least Glen's articulate writing was perfectly comprendohensible)

The reasons why I want SHF not castrated by the amplifier are beyond the purpose of this thread.
But i think that most people with subs capable of 20hz @-0.5db wouldn't like 25hz @-3dB like most transformers do.
I am sure, that an output transformer is better in all cases compare to each relais contact in serial to the output line for dc protect. Also a good solution is an appropriate capacitor in serial to the output line, if it was chioce a top quality version. Regarded a schematic with output transformer I have started this thread:Bob Cordell; 2043491 said:

To translate and understand of some specific english articles from the "Journal of the Audio Engineering Society" so as any US patents my english is already enough.
But after read this statement from Lumba I must say, my english is still very very bad, because I don't understand this clearly, even not with help of some translation tools.
Lumba has to do professionally with "Heisenberg uncertainty principle"?
for more information go to
Uncertainty principle - Wikipedia, the free encyclopedia
Uncertainty Principle (Werner Heisenberg)
If yes, I must go to find better language translation tools to better understanding Lumba's comments.

lumba,this principle is for very low energy scales..
amps are well beyond the level where it applies...
This is another ridiculous statement. Heisenberg uncertainty and Planck values describe the minimum of what can be measured in the universe. Period. There are some good amps and good devices out there, but they are nowhere near good enough, even from a simulation perspective, that signals are getting lost in the quantum noise floor.
On the other hand, you can model and simulate a tunnel diode in *spice. Tunnel diodes work because of Heisenberg uncertainty and the ability of small particles to tunnel through inpenetrable barriers, so *spice is not having a problem here either.
I do believe it's true that a design will never test as well as it simulates (unless the spice models are wrong). Spice minimizes or removes the effects of thermal interaction, EMI, RFI, line noise, bad circuit routing, etc. However, as a relative tool, its results are still perfectly valid. A design that simulates 1/10th of the distortion of another design, when built correctly, should in reality have considerably lower distortion than the implementation of the other design.
Of course, one of my main arguments with a lot of people in audio is that I believe that all this stuff works on well understood (at least by some people) physics; not magic. I don't believe in directional wire, or directional non-polarized capacitors. I don't believe in free-standing wood structures that break up bad vibrations in the room, but leave good ones alone. And I don't believe that a designer who is ignorant of the underlying principles of the devices he's using is going to achieve really good results, other than, once in a great while, by luck.

This is nonsense.
LTspice is extremely valuable for distortion analysis, especially when decent transistor models are used. LTspice provides tremendous insight, even if the absolute numbers it provides don't have perfect correlation with measurements on the actual amp built.
Is it the answer to the maiden's prayer? No, it is far from perfect.
Does it explain why ordinary THD measurements and simulations sometimes may not correlate with sound quality or hearing preferences? No.
This does not mean it is without value. It is of limited value to people who are close-minded, however, and do not understand that theory, measurement, and listening can co-exist to move us to better sound.
Cheers,
Bob
I think it is more "correlation vs causation uncertainty principle" that limits it, or limits the user. I find it very worthwhile for distortion analysis although inaccurate. Unfortunately there isn't a "judge sound quality" feature, so it is no more useful than probing a real circuit in this respect.
