Switch box & audio integrity


Will a cheap RCA switch box degrade my signal? I'm using for home recording to hook up 3 A/D converters to 1 monitor source. So, I really only need RCA Audio jacks.

Here's some links:

It seems this type of device may be appalling to serious audiophiles, but I can stand to lose anything the typical non-audiophile would not hear. So, how bad?

Other suggestions (<$100 since this is really only a matter of convenience)?

Thanks,

Here are links to a couple of additional possibilities, at higher price points, including the Decware model Roggae referred to:

Decware Zen ($329)

DB Systems DBP-2JAU/5 ($110) (click on the links under "DBP-2J/5" for further info).

I used the DB Systems switchbox many years ago with fine results. A possible downside, IIRC, is that it is fairly light, and it might therefore tilt upwards at the front if heavy cables are attached to it in the rear.

I'll add the Goldpoint products to the list; I think they have a selector-switch-in-a-box (fixed-level-passive-preamp, anybody?)

This fellow uses better quality parts and will even price out custom binding posts/wire for you:
