The method I propose assume you have a quality stereo preamp you wish to have remain in service for stereo listening. If a receiver with a high quality preamp section, in analogue mode (NO digital conversion for analogue sources!), is available than that is a simpler solution.
I had good luck with an Arcam AVR200. It has a pretty good preamp analogue stereo section. Now, this preamp is not as good as a quality tubed stereo preamp and I have yet to hear a solid state receiver that does. Some come close and the convenience may be an acceptable trade off for many.
The other method to eliminate the RCA switchbox is to acquire a high quality preamp that has a home theatre pass through. Or, if you are only interested in two channel performance (even with Dolby Digital sources) then you can simply run the stereo preamp outs from the TAPE OUT to an Auxiliary line level input of your preamp and simply treat the receiver/dolby digital sources as another component.
I have the extra speakers for multi channel reproduction but prefer to simply use the Lowthers (so far).
