Two Stereo Amps to Krell Preamp?


Hello,

I have two pairs of speakers I use in a two channel setup. I like to switch between the two depending on music choice. I'd love to pick up a Krell KRC HR but I see that the unit only has one set of Preamp out connections. My amps are RCA, BTW. Not balanced. My question is ... Did Krell make something to enable you to hook up two stereo amplifiers with a speaker selection switch to a single preamp at some point? If not, is there something that can be recommended to accomplish this or is it simply not a possibility? I really don't want to go to a processor unit at this time. I would really prefer just a simple stereo preamp. All help is appreciated. Thanks!

Let me run another scenario by ... Say I wanted to run both pairs of speakers simultaneously with two stereo amplifiers. That would simply require Y adapters off of the single set of krell KRC preamp outs????
