Help with two preamps and amp connection

This posting is seeking information in order to achieve two things:

1) to retain the integrity of the signal coming from the preamp
2) to make switching between two preamps (one for stereo, on for home theater) more convenient, as my current setup requires that I fumble behind an amplifier that is hard to get behind.

Here's the situation:

I am using one 5-channel amplifier for both music and home theater listening. Because I am bi-amping my speakers (each speaker gets two channels from the 5-channel amp, with the 5th channel powering the center channel), and both of my preamps have only one set of L/R preouts, I have attached one Y adapter (two males on one end, female on the other end) on the left two channels and right two channels of my amplifier. Thus, when using my stereo preamp, I run the L/R RCA outs into the two female ends of the Y adapters, giving me four input signals (2 L, 2 R) for use in the biamp configuration. When using the A/V preamp, I disconnect the stereo L/R RCA preouts from the Y adapters and plug in the A/V L/R RCA preouts. Fine.

The problem is that the Y adapters that I've been plugging into and unplugging aren't very long, my 5-channel amp is in a rack that is difficult to access, and I must struggle and fumble behind the amp to change connections between the two preamps.

I was thinking that to avoid this problem, I might incorporate a pair of female-female connectors as follows: put the female-female connectors on the end of my A/V preout cable (which is long, and easily accessible). When I want to use the A/V preamp, I simply unplug the RCA cables that run from my stereo preamp to the Y adapters on the amp (unplugging the RCA's at the back of the preamp, which is easily accessible), and connect these to the female-female adapter that I put on my A/V preouts (which are easily accessible).

I know this sounds confusing, but I think it will make things more convenient. My concern, however, is that all the extra connections (each signal will be subjected to a female-female coupling and then to a Y splitter) may degrade the original signal.

I've heard that long runs of line-level information are okay, and my runs are quite short, but they will be "interrupted" in the sense that there will be two RCA's joined together with the coupling and then to a splitter. I don't know if these interruptions incorporate distortion, or just lower the voltage of the signal. If it were just the latter, then wouldn't I just be able to compensate with some extra gain?

Does anyone have any suggestions on how I might more easily accomplish the use of two preamps with one amp? I guess the Y splitters are a necessity due to the biamp configuration, but it is the other connections that I am most concerned with.

I'm sure they may be splitter boxes with switching mechanisms I could use instead, but I don't know if this is worse than using cables/adapters. I want to degrade the original signal as little as possible.

Look up the thread "Theatre Bypass Mod for CJ Preamp?" - there is some good advise there. I am still swapping cables to go from theatre to music ... But I did find a guy to do the mod described in the post. Good luck.
do yer preamps have a tape loop? if so, have yer audio preamp hooked-up full-time *only* to the two main audio speakers/amps. listen to music as always. then, for movies, have yer h-t preamps' main outs feed *only* the center & surround channel amps. for the two *front* h-t channels, feed the tape outs of yer h-t preamp into the tape ins of the audio preamp. when watching movies, set the audio preamp to the *tape* source. you will need to adjust volume for the main channels (audio preamp) & the center/surrounds (h-t preamp) separately, but ewe shouldn't have to do any more plugging-unplugging.

of course, ewe could get an audio preamp that has a true processor default-loop. hooked up as described, (except your h-t preamp feeds the audio preamps' processor loop instead of its tape loop), the h-t preamp will control the wolume of the speakers hooked up to the audio preamp, as well as the center/surround speakers...

confused yet? ;~) good luck, doug s.

Thanks, Sedond. Slingshot's earlier post led me to a thread that made a similar suggestion as yours. I think that is the way to go. I appreciate the help.
