Yeah, right... it all very simple... when you know it...

It is relatively simple ;O)

Hm, we are actually not very near just yeat.

Eh, no. I was refering to the "flexible" tubes being in used for
better "cables" in high-frequency designs. Coax but with copper tubes.
Looks really cool but is *WAY* overkill for audio (but is a good idea
at 40 GHz).

Cheers,
