Is brass pipe a suitable conduit for housing audio/visual cables between my TV and amp or is it just going to create some sort of Van der Graaf Generator?
My instinct says it'll be fine. The signals will be fairly low power and digital pre-amplifier so there shouldn't be anything induced in the pipe and I can't imagine there being any trouble with your signals unless you decide to put a current through the pipe (don't).
I'm no expert though.
