I hope it's not Kevlar

Why ? They conduct electricity.
(the isolation is made of several different foils, last one a thin plastic transparent, kind a Mylar).

No they don't conduct. The only thing about Kevlar is if you have to cut it. Otherwise what's the problem?

The cables, conduct electricity, not the isolator, as expected :-)
In fact, may-be they is some Kevlar, they are yellow and boring to denude.
Did i have to add Kevlar in my evil's list ;-)

Right, he mentions JC Morrison a perfectly fine guy, but his approach is more like a painter, there are still painters BTW that grind their own pigments some of which are fabulously expensive. He has a large gallery of schematics many realized in the flesh. I think the engineering as art angle is overstated in engineering it would be like the process is the point.

If yet another triode connected pentode and some MOSFET's makes good sound that's fine. I have a hard time seeing a learning process in this approach.

Does that give you the audiophile desired plenty of 'air' in the sound ...?

But seriously, semi-rigid is good, very good; we don't want anything vibrating, apart from the speaker cones ...

Air is a problem, yes, when we listen to music: we cannot keep the window opened because the neighbors.

"All quiet on the western front." I guess we can move forward again. Unfortunately, what I am now working on, (improvements to power amps) is confidential, but I will say that I am sticking with the complementary differential jfet input that I have used for so many decades, now.
If anything, I think that RFI buffering is more important than ever. Heavy Class A operation is VERY IMPORTANT, as well.
I still have not found any IC that I would use in replacement for good discrete design.
They are just too compromised in idle current (too low) for me to be comfortable with them.
People are always asking me for cheaper and easier to build designs. Unfortunately, I don't have any. It is not what I do. I try to make the best, most elegant designs I can think of, in respect to the price point that I must work to. I'll leave IC's mostly to mid-fi, where people suppose that everything sounds the same, anyway, as they have been told by others. '-)
