... 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.
