The Aristaeus is indeed a version of the HEV90 circuit but with a proper PSU and much better parts and build quality. The T2 is really a supercharged version of the original SRX circuit (which the ES-1/2 used) with some really clever stuff in there and CCS loading for just about everything.
The BH is Kevin's take on a similar concept without ever seeing a T2 amp in the flesh or the schematic. He didn't see either until he received my old amp last year and by that time the BH circuit was nearly 10 years old.
The BHSE is a further development of that same circuit using components which weren't available when the original circuit was designed. The biggest change is in the output stage CCS which now uses just a couple of transistors as opposed to 14 in the original design plus the resistors needed for each of them. It's also a better layout and is more stable for long term use. The BH puts off an ungodly amount of heat (200W or so) and controlling where it goes is the only way to make sure these amps will still be functioning as new in 10 years time.
Now there are new amps on the drawing board but whether or not anybody will make them commercially is hard to say. As we continue to push the boundaries things get expensive, very expensive in fact. If the DIYT2 were to be sold commercially then it would be at least 15K$ if not more in its most basic form.

He was even told how he could fix the amps once and for all but he just didn't listen. A full year before I posted the internal pics of my amp I posted a thread here which warned about everything which turned out to be wrong with my amp. Jude had to pull it as Mikhail accused me of making it all up (and I didn't have an amp in my possession to back up my claims, it was all based on internal pictures which I couldn't forward) but Mikhail shipped out quite a few broken units after that was posted.
