As nothing is affordable on the open market, I'm planning on building
a switching box so that I can connect two 5.1 sources to the 5.1
analogue inputs on my amp. I was planning on using 3 double-pole
relays (BT47's) for switching the 6 channels. These would be
switchable by a front panel switch. Obviously, the unit would run
from a 12v power supply. How well would this work? Would the relays
cause sound quality issues? Any help would be appreciated.

I'm sure you can find yourself a six pole two way switch that will do
the job without all the bother of power supplies.

There are no sound quality issues whichever way you do it.

I was originally hoping to find a six-pole switch, but can't find one
in the CPC catalogue. Also, wiring up all the bloody wires will be a
nightmare :-(

Radiospares have stuff - like this 6 pole 2-3way

And of course wiring it all up is a pain whether it is switches or
relays.
