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,

Try one and see. Not much to loose.

I use a switch like that I got at Radio SHack years ago for about $20 with my second system. It works fine there. I might be somewhat concerned initially using it in my main rig, but I would not know for sure until I tried.

In general, I would try to use a pre-amp with enough inputs built in first, but not hesitate to at least try a switching device if needed, especially if of decent build quality.

I would recommend Niles as a good quality brand to try.

I do use a Niles speaker switch in my main rig to switch in various speakers in various rooms, including my main speakers, the big OHM F5s, with no noticeable ill effects.

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:
