Fake bi-wire with two amps

@wbs seems like nobody interested in answering this question. Ask before I do it cause I don't want what @tony1954 said happened.

@tony1954 i didnot see any connection between my question and the Russian Roulette. But anyway, let's see if my next post gonna be how to repair or not. At least it's gonna be some funny experience in my hifi journey. There's always some new ''idea'' pop out isn't it

First, I agree totally that this is a bad idea.  A year or so ago my nephew called and asked me the same question.  He wanted to connect two amps to the same speaker terminals and only power up the amp he wanted to use at the time.  I told him it was a bad idea and strongly advised against doing so.  And I feel like this is an inherently bad idea.  But aside from opening the door to possibly accidentally powering up both amps at the same time, I really don't know specifically if there are other likely problems.

Can someone with the tech chops chime in?

Why do I get the feeling that your next post will be you asking how to repair fried speakers.

Are you familiar with a game called "Russian Roulette"?

I got a good one off of Amazon. Very well made and solid. Note; You don't want to turn the tube amp on until you have the speakers switched.

@steve59  bingo, totally correct, without a switch box. I don't trust the switch box, the build quality and material will effect the sound quality and characteristic for sure. I can underdtand the speaker cable conncected become a capacitor with very low capacitance. But other then that, it will drained power even with a open circuit (the tuerned off amp) ?

@russ69 thanks, but as I said above, I don't trust switch box, just don't like it. And I have two complete setups, from the dac to amp.

You need a switch box.

So you're asking if you can connect both amps at the same time without a switch box so you can pic which amp you want to listen to each time... Every shop or review I read either uses a switch box or puts simple banana plugs on the amp end to change amps. I'd say no, The open from the wires feeding back to the amp turned off will drain power from the powered amp and do something undesirable.
