Or leaving conventional power supply topology behind, and using multiple independent supplies in the proper way😀

You make salient and pertinent points. This is why there’s such a price discrepancy/spectrum for 300b amplifiers. They range from 500.00 to 50,000.00 USD. Implementation and quality of the power supply/driver stage and output transformer has so much do with what you get and hear.
I wish you much success with your new 300b PP amplifier at the Seattle audio show. It sure seems it is a winner.
The sound of these amps continues to blossom by the day, providing the most realistic sound presentation I have ever heard in my room. The images are palpably real with a pure tonal correctness to the music. I forgot what Don sourced for the stock tubes, but he recommended much better, but yet still afforable, 300b Linlai tubes, which is tells me will be even more revealing. I have rolled a boatload of input tubes in gear over the years, but will be happy to rely on Don's recommendations for affordable 300b tubes. By all accounts, Emission Labs also makes excellent 300b tubes, but they are nearly twice the cost of the Linlai tubes I ordered. Honestly, I could easily live with these stock 300b tubes, but Don assures me the Linlai WE300b tubes will provide a significant SQ improvement.
It is so good and refreshing to read how much you are enjoying your Don Sachs 300b amplifier. I’m on my 2nd pair of the EML XLS 300b tubes. They are superb! However, I’d trust the Lanlai 300b recommendation from Don. I am lucky in that I only need one pair of tubes for my SET amplifier. Your PP amplifier obviously requires 2 pair of 300b. Things can become expensive quickly.😊
If he said the sound quality further improves, I believe it based on my experience with various 300b tubes. Keep us posted.
Thanks as always for your positive comments; you set the high mark for thoughtful and erudite comments on this forum, once and always the most generous and civil gentleman on all audio matters. It would be a delight to meet you one day.
I got a quad of the Linlai 300b tubes recommended by Don from his Chinese supplier for $800, which is ~40% of the cost of the Emission Labs quads, yet Don admits that your tubes are even more revealing than the Linlai tubes. You have to pay to play with these tubes, but if Don is using these Linlai tubes in his own 300b monos, that is good enough for me. I sure hope they are long lived. ;-)
