AQ"s DBS A reality?

[jneutron]

I am an electronic engineer by training and trade

You have my sympathies..

Me too, btw..don't think I'm dissin ya..

many things I was taught professionally seem to be simplifications of the true process.

Yah, the actuals can be too complex, and hinder use. Skin effect being one of them, with improper use of the "exponential depth" approximation..

and many claim that any properly designed amp is indistuingisihable from any other well designed amp)

Actually I would claim the same thing. However, that said, I also have to say that there are NO properly designed amps out there. Some are better than others, but the designers are just shooting craps without understanding what's going on. Random, random..random..
