Quality RCA In/Outs on the back too. Machined, not stamped would be nice. That way when I select Music on my 650. It will turn off the avr and whatever else was connected to it at the time. And switch the speakers to another Input. I def won't do Pass-Through with my avr. My budget is $300.
PS: I'd like it to not have Volume control. Unnecessary signal path, etc.
Any/All Mac owners, please chime in.

You have a decent speakers and amp, you need to be a little careful in buying a speaker switch. I don't know exactly what's in the market as I build my own. You need very heavy duty relays to switch the signal, not just any cheap switch box. My advice is NOT be fancy and want remote, just be thankful if you can find a really really heavy duty 2:1 switch, DON'T get fancy looking for 5:1, remote and all.
I can tell you my experience in building my first relay switch unit that FAILED. I already used big 40A automotive relays with 12 gauge connecting wires AS SHORT AS POSSIBLE. It degraded the sound to the point it's not useable. It's now in the shed.
Now I just designed another one to give it a second try. I use TWO 40A relays together to further beef up the signal path. Total relays count is 8 to make a 2:1 switcher. I actually made a PCB with heavy thick copper to minimize loss. I don't even use connector, instead solder the speaker cable directly onto the pcb to minimize the signal loss. I still have to see whether that's good enough. Just the parts alone is over $80. I do have wired remote. Even with all these, My confidence level is only 50:50, I am not putting a lot of hope, but I do a lot of comparison test, a 2:1 switch with even wired remote will make it convenient to do DBT, so I just give it another try.
I hope this will give you some idea. If you find anything you like, post it here and I can comment a little whether it even look heavy duty enough.
Attached is the picture of my FAILED 2:1 switch
. Look at the size of those relay reference to the banana speaker connector, look at the size of the wires. This is the failed
one. If you see one with same size or smaller relays, it definitely will NOT perform any better.
