URL Collection of Commercial Single Ended Integrated and Power Amplifier Devices

After read the article "Single Ended Class A" from Nelson Pass about www.firstwatt.com/downloads/seclassa.pdf and after simulation and test of a wide range of different circuit designs I hate the so called "True Complementary" circuit designs for output power stage, because the true complementary power transistor pair is for me a mythos resp. a tall story. The perfect symmetric character exist in the mind of most well-known famous designers so as on the schematic diagrams, but not in real life; both by BjTs and MOSFETs. Nevertheless - unfortunately most of the audio amplifier designs are make in this kind (or I find designs with output tubes).
Therefore the follow URL collection of all commercial amplifiers with output circuit solid state designs without the so called "True Complementary". I have found all listed URLs below on the web in the last years.

If URL already death, please use http://www.archive.org/web/web.php and copy this death link about right click.You get a chronology overvview. At second step you choise the wanted date of the archived webstite. For example:
www.passlabs.com - copy in http://www.archive.org/web/web.php - click on "Apr.06.1997" and you see the website from "Daddy Pass" in the Aleph aera 12 years ago.

SE versions with very high idle current (> 4A) and low output power (arround 5W) especially for high quality tweeter drive (e. g. SA8535 from Stage Accompany) in bi-amping systems, I found nothing.

I hope, for some members this list offer a good overview. It is very hard to find such overview on other places in the web, because the most designs of amplifiers - as mentioned earlier - based of complementary transistor pairs.
If not, I have to do in most cases with tube (valve) output power stages.

Perhaps some members know about additional interesting URLs from commercial brands.
Please excuse my not perfect english - I work with the language tools by google.

Are there news about currently solid state single ended power amplifier?

[Bone]

It would be nice if these links led directly to the schematics of the amplifiers so that a comparison could be made.

I think so, too, but unfortunately the most commercial brands don't release their circuit diagrams/schematics.

Are there news about currently solid state single ended power amplifier brands?

It's a pretty thin category.

there are several new additional kit suppliers, but where are the commercial brands of such amplifiers?

A new power amplifier from Reimyo:
model KAP-777
perhaps a "Single Ended" classA
about
REIMYO KAP-777 Power Amplifire
I read
It’s a unique Single Mos FET driven power amplifier
Perhaps Class-G with Single Ended Class-A main part (see data for output power)?
Who knows more?
