supply that I did. The name was also one I gave them. Before that it was a single supply to both tubes and the sound was flatter and less dynamic.

A very few tube (non-mono) power amps have dual supplies (one for each channel), although in some cases each PS only is dual in B+.
What is a dual pseudo PS?
PS. One main power supply but divided in such a way with resistors and caps that each channel has a reserve as if it were dual PS. No sag from one side using due to more draw due to music passages. Better dynamics and imaging, among other things. I have built dual supplies just to compare, and achieved the same results as a dual supply using this method. The extra resistors and caps also drop the ripple to a lower level.

Are you referring only to pre/driver supplies? Resistance degrades dynamics and regulation. It's not usually practical for output stages.

or anything else with the right RCRCR network. Just an excellent improvement in sound, which is why Jack adopted it.

It's not about what I hear, it's about the laws of physics. Series resistance degrades PS regulation and dynamic response. It'll take more than a statement that it "sounds good" to invalidate that.

it is hype. It works, Woo Audio uses it because and only because it works and that is what matters, it works.In response to TK.

John PA, You designed that power supply?
what I did with a 6 a number of years ago and then told Jack about and the improvements in sound. They also incorporated it in another amp using the same name.

head-fi? Lots of work done on that unit.
I did a maxed out 6 with the Goldpoint, all Blackgate caps, the best resistors etc. I had a guy come over and asked me to modify his years ago and then compared it to amps cost 2 to 3 times as much and preferred my modified 6 to some highly acclaimed amps. He was happy.

you barely fit all that into it! :)
I can just imagine how it sounds too! Nice work!
and everything was bipolar Black Gates or the high voltage ones for the plate and I used 3 per side for the plate.

Great Job! The power supply is a huge part to any design and to the sound of the unit.Even though I have only little less than 20 hours on my WA6 since the change of the Rectifier tube to the JJ GZ34, I'm hearing things I never head with my Fostex T50RP headphones. I'm hearing very good separation in instruments and in tone of each. What I mean is I hear a nice clean keyboard and when the guitar player solo's that has a slightly dirty sound, you can actually hear that dirty sound stand out from the rest of the other instruments. Snare drums have a nice texture to them. Plus, cymbals have a nice natural decay now. Horns and vocals sound real.
I can only imagine what this WA6 will sound like when it has 50, 80, and 100 hours on it. Also when the Sophia Mesh plate is put in with the 6SN7 tubes.
I'm really happy I bought this WA6 headphone amp.
