I've had a pair of M3s for awhile and after setting up multiple systems around the house ended up hooking our old (late 70s) Kenwood KR2600 receiver to them. This setup is the sweetest these speakers have ever sounded -- better than all the digitals that preceded.

Problem-- the 2600 has very few inputs. In that room, I've wanted to play my Sirius radio hookup. However my Sirius hookup is to a Sony home theater receiver. On previous forum input I found I could do a "tape out" from the Sony cabled to the "tape in" port of the Kenwood to hear Sirius.

But when I do this, all other audio from the Kenwood sounds quite muffled, for lack of a better word. I tried a cheapo audio selector box that I got from Radio Shack a long time ago, but the other inputs still sounded muffled -- and the Sirius sounded very faint.

Is there a good audio switch that I could plug into the Kenwood Tape In that would really isolate the Sony when it's off and stop muffling the other inputs? I also have a cassette player that would utilize another port of a switch. And I'd tried a Y adapter to input both the cassette and Sony cables into the Kenwood's Tape In, but that produced the muffling of other devices too.

I'd like to have something that could keep everything attached instead of constantly attaching and removing the cables from the Sony everytime I want to listen to satellite radio ...
