I have been cautioned against the idea, apparently if the speaker sees both amps at once, (in a non- biamping way), bad things can happen, can't remember what. Maybe best to get a switch that does not even allow for both to play at once, to avoid accidents?

Just use banana jacks on the speaker wires and manually plug them into which ever amp you want to use.
Even if you use a switch it only takes a quick contact and you will blow an amp out.
Yeah I guess I should have thought it through a bit more ... lolSometimes I don't mind asking a dumb question when there are folk who can quickly say ... use a speaker switch ;)
Now I think of it, if the SS was on it would see the tube amp as a (large - I suspect) inductive load (that and the speaker) ... doesn't that cause a Naim or Quad (?) amplifier to go radioactive?
The other way around I suspect you'd encounter a capacitor when not "dc" direct ... also not good but don't imagine it world cause anything to pop.

Don't even do it with a speaker selector...just get another set of speakers
. I was in a situation where I have my home theater in the same room as my listening system, I ended up using a nice little pair of Minimus 7 for the home theater amp and running the big boys through my tube set up. Couldn't be happier...for now. LOL

For the amps which is set to the "off" position, it'll be a no load position. That means, the output stage'll have no load to work into. You'll have solder some goodly sized load resistors for each channel. Otherwise, depending on the amp design, the amps will either have unnessesary circuit stress and parts aging, or total failure.
OTOH, I always say that direct, personal experience is the best teacher. There's nothing like learning about electricity than sticking your finger into a live electrical socket to see what happens and test your wonderful ideas.
I did that once...when I was 3 years old.
You might be playing with fire, literally.
