I can do it if I really want. But it won't be a hobby after that. So far my goal is get to 95% of it at 1/10th of cost. That is what hobby is about. If I help someone on the way, it would be an additional benefit and source of satisfactions too.

I want. But when I am in recording studio I hear studio monitors. Every time, in different studios. Including such nice monitors as Barefoot.

From other hand, at home I don't have such studio monitors that were used during mastring sessions. But sometims I close my eyes and hear sounds as real, forgetting about speakers and amplifiers...

According to this Barefoot Sound | Vintageking.com you can get a nice 5.1 setup for around $20K. This not out of reach for many people - compare it with price of Honda Accord or other "affordable" car.

Hi Bigun
I appreciate very much your feedback, tomorrow I will read the article you mention, I'm very tired now.
I just wanted to do a thought experiment and look what resulted.
I think my explanation did not like anyone, but I think to be right, as a phenomenological explanation seems to me well.
Best regards
Johann

Sorry for my curiosity, but if your picture is not that time, you have more than kept secrets of aspirin.
I would like to grow old that way.
Best regards

Try on studio monitors, do they sound real?

Popilin,
Keep after your experiment.
I searched through the DIY pages for The Valve Wizard and found this The Valve Wizard
Check out the Wizard for SRPP there is a calculation for the output impedance. I believe your previous estimate did not return the best number, I think that is likely somewhat lower.
That thing may work better as a driver than you give it credit.
