doofus rotary switch selection question

[leebob]

I want to build a BrianGT kit as an integrated stereo amp with asimple potentiometer volume control and input selector..I'm looking for recommendations about the rotary switch...(2) pole-6 position with common ground on the RCAs and switch only the hot leads, (3) pole with common tied between pairs, or a (4) pole switch with "x" number of inputs...I realize this is a painfully ig'nint question but I want to avoid snaps when switching, inducing hum, and so forth. I don't mind paying for a good switch, either. I would like to have (6) inputs if possible.

One more "noob"-ulous question...Stepped attenuator versus simle log taper ALPS...that much difference?

Once I get my house sold, and life settles down for a while, I'm going to build a pre-amp. I'm planning on using a 5-pole switch, switching both hot and ground of each channel, and the fifth pole will switch LEDs to indicate which source is selected.

On Topic: Switch both the signal and the ground for best performance. Do not use a common ground-point.

To avoid the snaps, buy make before break switches

I know what that's like! The only decent switch I could find was break before make... I need to find a way to stop the pops! Arrhhh!!

Suggestions on a post card please.

Thanks to all for the responses...answers beget more questions...

why is switching the ground along with the positive terminal on a selector switch more preferable to using a bussed (i.e. common) ground? It's not doubt as much as pure unadorned ignorance on my part...as the famous Cuban band leader Ricky Ricardo once said..."'Splain it to me, Lucy"...
