RE: What's all this "modern" power supply?

> There is no single definition of what "modern" is,

In technical terms It means recently developed, innovative.

So called low DCR supply (in fact, primitive CLCL topology backdates probably to the beginning of 20th century if not earlier) mentioned countless number of times have nothing to do with innovations. Additionally, it is so poorly engineered so is suitable only for low power SET with nearly constant current draw.

May be for 1% - 3% of audiophiles and enthusiasts out there, and suppliers of boutique items serving this market, but for none of professional electronic engineers.
Don't believe me? How many professional recording studios out there using those 2A3 SETs (or any other SET) as reference amplifiers? 50%, 15% or 0.01% worldwide?

The last time I saw SET used by professional musician only as guitar amplifier, where all 2nd order harmonic distortions, highly colored sound, and soft clipping are very welcome.

I admit some people enjoying SETs, and I'm glad they are happy doing so, but this ancient old technology can be called modern or innovative only if compared to the door bell.
