Re: Being one of those 'hard nosed' non belivers ...

I'ld be more comfortable with simple descriptions of the perceived changes. The misguided attempts at technical justification, usually accompanied by excessive punctuation, capitalization and uncritical high-handing are an embarrassment. It gives the whole affair an unpleasant messianic vibe (especially the mid/hi/ultra-fi BS.)

Have to agree on the second, there’s no question in my mind what’s described as ‘faster’ is often ‘reams of higher order distortion components.’ Not saying it’s the case here though I also have to wonder just how much PS modulation is occurring and how it manifests on the output.

All that said, I have benched and measured a low-DCR test mule and tuning the first LC section – in this case 0.07H @ 3 ohms into 6.8uF - easily doubles the supply stiffness. It’s an approach worth investigating.

Thermionically addicted.
