I'll be buying a rotary switch to change my sources. My question is, would a 4pole or 2pole (6 position) switch be better? With the 4pole I could keep grounds separate, but that comes at a hefty price premium. Are ground loops an issue or will I be fine with the 2 pole switch?
tying the grounds all together is an option and only switch the signals
cross talk between active sources though will be an issue
switcing also grounds will not help much in crosstalk be tween active sources ...
my approach is to use one pole switch to DC drive 6 relays ( 2 pole each ) and shunt the signal of not working but other than that may be active sources to ground via a resistors ...
from all i ve heard that was the most quiet active sources or not !
(i could live with some crosstalk from an other source WTF!! just shut it down ... but actually i hate crosstalks from the other chanel !!! )
kind regards

In my experience it is usual to only switch the incoming signals and to join all the incoming channel grounds to a common point. That is use a 2 pole switch.
Incoming grounds should be taken to a common ground point by the rotary switch and that point connected to the star ground which is usually located just after the main power supply capacitors. If you are unsure about grounding I suggest you read articles by Nelson Pass on the Passdiy web site.The articles are excellant and easy to read.
