Default A Selector Switch?

How important - or is it even necessary to have a selector switch to rotate between two incoming sources?

What do you mean? You want to hook both(or multiple?) sources all together and not switch them at all?

If you are comparing a rotary against a toggle switch, I think the rotaries are far better in the long run. They tend to wipe the contacts off and remain cleaner than toggles. I just put together a DACT based input switcher and I will tell you that just looking at the build quality and construction of the switch, there is no doubt it will outperform a toggle for years to come.

Correct. With just a CD player and a FM Tuner (2 inputs only) I thought why not bypass the selector switch and run both inputs direct to the board? I don't plan to play both sources simultaneously, it's just more of a purist approach that is what I'm after.

Not a very good idea. The output circuit of you FM tuner is now part of the input circuit when you play CD, and vice-versa. Some output circuits can be very weird when not powered. You'll lose way more quality than you would with a good switch.

Thanks Panomaniac, I appreciate your response and expertise. My CD player is actually a Pioneer DVD 343 modified by Steve Deckert (Decware) and it has a SET output stage that remains powered up even if the unit is switched off. This would probably make things even worse for not having the switch. Since I do not use my tuner that much, I could get by with a single pair of inputs and manually switch them over on the rare occasion I want to listen to FM.

Thanks again.
