... so that the input to the main stereo amp & speakers toggles between the output from the Plinius M16 preamp and the output Meridian 861 processor. If the switch is set to the Plinius M16 then the Meridian is not switched on so an uninterrupted analog stereo signal goes through from the M16 to the Plinius stereo amps.In your case substitute the output from the Onyko for the 861 above.
But maybe you only have amplifier, not preamp output from the Onyko. This would involve a 4 pole rather than 2 pole switch. The switching would be -
Stereo speakers -> 1. Onkyo amp output
-> 2. Plinius SA100Plinius M16 -> 1. No connection
-> 2. Plinius SA100This would mean that in position 1 only inputs to the Onkyo would play through the system. In position 2. only inputs to the M16 would play and they would only go through the main stereo pair. You could not use any Onkyo DSP modes on the M16 inputs unless you fed the second output from the M16 in as another Onyko input (what we do).
Use a high quality switch. We remote control ours via a 12 volt supply but a physical switch would be fine.
BTW we find the Meridian 861 does not audibly corrupt the analog signal so have found our switching system somewhat redundant!
Hope this helps.

... that when the change over switch is used that the ground is switched first if using single ended connections, this may be system dependent though if you have problems or not. I set up a switch system also and at the time I had a Yamaha DSPA1 which didn't like the switching ie 2 pole used for one channel, another 2 pole for other channel, it caused a spike which in turn caused the amp to spike and speakers to jump, horrible sound and a real heart starter.I found by going to a switch that only swapped the hot center signal and joined ground return signals stopped the spike and luckily the speakers weren't damaged. I use balanced cables now and go through the hassle of physically changing the cable so I get direct, no more connectors in the chain, when I change from audio only to HT.
Good idea, you just need to experiment abit. Good luck.
