His designs were for his enjoyment . He championed large single ended triodes , direct and transformer coupling over capacitor coupling , and driving the power tube with the same power tube . Because of all the iron these were overly heavy amplifiers , and expensive to make using only the highest quality , sometimes custom-made , transformers . An innovator , not by the book .
Sorry, this is not high fidelity but mid fidelity at best. Very colored and boxed sound, no highs over 8 Kz , no bottom end but only a captivating (maybe) midrange. No power cords, no good connectors, no top notch internal wiring, no state of the art capacitors...
I'm sorry mister, but I must advise you that mr Sakuma's amplifiers did, absolutely, NOT matched ANY "top quality" nor "state of the art" standards. His design was purely based upon human perception and not in scientific resources. Aside of this, you must consider also that you're listening a mere camera mic recording wich much probably won't represent 10% of the produced audio. Unless you already heard one of his amplifiers in person, I shoud pose your comment as very unfortunate.
@@paolo60333 how come you can tell if it's hi fidelity or mid fidelity from a system. True music only comes from the instruments itself. As much as a good system can give to you, only the level of naturalness of sound can be obtain from certain system plus with you aging ear your evaluation is not accurate and subjective. By the way wiring doesn't change the quality of sound.....LOL caps do but only the tone we sometimes refer as quality...
