Integrating tube amp with HT

I run separate speaker wires for my tube amd and home theater amp and switch cables.

if you have only one set of spakers, and one set of spaker cables, but two amps... you have to choose which amp you wish to use to drive the spakers with. Just switch the cables from the tube amp to the receiver, and when done there or you wish to use the tube amp switch 'em back.

BUT if you have a processor input on your ARC preamp, run a pair of analog cables from the monitor outs on the receiver to the proc inputs of your preamp. turn on the rec, and pre, & amp, and no swithcing of the speaker cables is needed.

to use only one amp or another with the same spakers... you will have to switch your spkr cables back and forth from amp to rec, and so forth.

there is no other way with your current setup.

Might consider adding a preamp to coordinate the two
I use a ConradJohnson Met1 5.1 tube hybrid analogue pre.
Two 5.1 amp inputs, speakers out, and cable, cd, tuner, bluray, sacd in. All you need do is turn on theamp or reciever you want to use and switch between players with the remote. Works great but requires lots of analogue interconnects.
