Hi anm and iaudio
I am posting the picture of setup for connecting two amps to one set of speakers.

There are two sets of four banana plugs fixed on the wooden piece.
Each set connects to one amp ie the first set to tube amp and second to Onkyo amp. The banana plugs connected to speakers are shifted from one amp to another by just removing them from one set of banana plugs to another.
Thanks
Anil.
