5 channel amp switcher?

I am looking for a switcher that I can use to switch between two 5 channel amps to a 5 channel speaker system. There are plenty of line level 5.1 switchers, but after much research I could only find a 10 year old niles product the (AB-8)that is no longer in production. I thought about using 3 dps-1 switches, but that would be a total pitb. So I am open to suggestions of other products. I want to use a 5 channel tube amp for music, and a 5 channel SS amp for movies and run them to the same set of speakers. Your help would be greatly appreciated.
