Hi SergVK
Very nice design. Is the prototype ready and working?
I'm a bit affraid of the servo mechanism. It can lead to some minor oscillations at very low frequencies if input is DC-coupled because of 180 degrees phase shift. Who knows what's on the output of a preamp. Maybe a cap, maybe no cap.
Regards

Many people already assemble this amp and no any problem found with servo.

I get a "load error 286" when I open your eagle files. Any suggestions?
Thanks
I download and open all eagle files successful.

That means that Eagle thinks the file was created by a pirate version.
If SergVK can open it he may have an earlier release.

Thanks for testing it, SergVK
I downloaded the zips again and got the same error.

Thanks, looks like I'll have to redo it for Eagle 4.15 light, but before I even think about it, is anyone else having problems or is it just me?
Thanks

There is complexity in the two stage diff arrangement for which there is no evident reason, at least to me. Why?
It has a high component count.
It price of low thd<0.03%, bw~100kHz and excellent music reproduction.
