Let's talk shielding. I'll start of with a couple of questions.
- what material is best for "audio frequency range" shielding?
- We use to shield audio cables in tube equipment. Would it an idea to shield heater PSU cables as well?
( ....keeping the interference within the braid around the heater PSU cables....)
At RS they sell this (264-9310) expensive but interesting metal braid
Can't find any info on shielding quality in the audio frequency range though...

A sheath manufactured from silver plated nylon fibres
Offers effective shielding for cable diameters from 8 to 20mm
Technical specification
Electric field shielding effectiveness: 64dB @ 1MHz
---------------------------------- 55dB @ 10MHz
--------------------------------- 44dB @ 100MHz
Magnetic field ---------------------- 8dB @ 1MHz
Plane wave ----------------------- 43dB @ 400MHz
----------------------------------40dB @ 1GHz
