That certainly looks interesting The symbol they use for an opamp is an unusual one though

I agree. The symbol they use for an opamp is in USSR standard with name Unified System Design the Documentation.

Yeah except at what Voltage output are the THD figures specified and what about inband intermod i mean it's fine to rate IMD at 19Khz and 20Khz but would like to see actual inband specs and are they measured or predicted Also like the drive on the constant current source similar to the OPA SUN V2, but all those base emitter junctions means we limit the output swing to about VCC/VEE - ~2V probably more to keep the distortion down. Maybe run the supply at +/- 20V and regulate down for the opamp.

THD and IMD at 19Khz and 20Khz certain frequencies are suppressed in accordance with loop by reinforcement on this frequency. Loop reinforcements it is enough

It does not look that advanced, is there a kit us noobs could get our hands on ??
And is the design finished ??

The Project completed. The Kit no. I live on Ukraine. This far, mail works bad and long. The Amplifier has at most high parameters, but adjustment requires presence of the oscilloscope.

"Dear Sir, many thanks for your outstanding service. My MEST [that poweramp] has been checked by my technician. He's simply a genious. Now my MEST plays superb. I never had an amplifier at that level! I had before Gryphon, Geld Note, Mastersound, Pathos ... but never an amplifier so perfect. It really is heaven on earth. What a realism, power, details , smoothness. All THE qualities together in one heavenly build amplifier: simply heaven on earth. My ultimate congratulation to all the employees of MEST. All the outmost best qualitys in a "small" country. But it's not a matter of quantity but of quality! There is onle 1 problem: you get addicted to it. So you need a lot of spare time. So be warned ... Many thanks that I may buy such a wonderful jewel! Have a nice evening. Greetings, Ronny Velter.
