It seems he doesn't care, about some things, though I'm not sure what, he cares about his ego for sure, mixed mode fb, calling it something else, and didn't he come up with the idea, even a resistor in the speaker wire becomes motional feedback. His aim is mostly to confuse, very strange.

Yes, the hoofing great transformer in the way. But no point going round in a circle again. My initial comment was aimed at Joe but Tournesol stepped in the firing line. As after 3 attempts my point is being missed time to drop it as there is no benefit to be had.

OK we have entered the twilight zone. That or Mark has been replaced with a Turing test that we have all failed....

I meant that, I don't do discrete PA design. At my age there is too much to learn about all the discrete power device physics to do something SOTA so I spend my time elsewhere helping where I can.

Come on, he's talking about sounds better, surely we are under no illusions about what that means? (Bob excluded )

I missed this, so upsampling CD's adds information or is it still unmeasurable behaviors of DAC's?

It was the vinyl comment that raised my eyebrow. I'm happy to accept that digital filters can sound different even if I personally don't care.

I kindly thought the same thing but after researching a little apparently the dsd will bypass certain parts of the dac chip that introduces noise. So there is a plausible reason.

Supposedly Works ‘better’ on some dacs than others.

Seems this one fell hard on my toes and others including SW.
