Switching between two receivers — one set of speakers

Don't know about the sub

Thank you lordmelton.
The sub is really what I struggle with. 
I considered the Douk VU3 Pro (I like those meters), but the Schiit is most likely better quality. 
Either way, I’ll need a solution for the sub. 
Can I do something with a Y-splitter? How would I wire that though?

I should probably mention that both receivers have pre out and the sub is active.

This is what AI said to me when I copied your inquiry.

Friends don’t let friends buy receivers…..

I use Maple Tree audio.  He will make whatever switching combination you need.  I bought one that allows me to switch 3 sources between 2 amps, one set of speakers.  One is SS and one tube.  The switch has a built in load for the tube amp.  Well made. Solid. As far as the sub, I use a REL with the speakon connection so its always wired in to the speakers. I think other sub manufacturers have a similar connection. 

Thank you, gkelly — or thank you AI?

A custom switch by Maple Tree would be ideal. It could accommodate some additional switching as well. And the REL would be a nice upgrade to the Klipsch. 
I just don’t have that kind of budget right now. 
I may consider these kinds of upgrades once I’m happy with my overall setup, and aware of all desired switcheroo.

I’m no expert, but I’m about to do the same thing. My source will be Qobuz streaming through my Eversolo DMP A-8.  I have one amp (Primaluna EVO300 INT) connected to the Eversolo via the “rca out” and the other (Yamaha A-S3000) connected to the “balanced out”. Both amps will have speaker wires connected to my Cornwall IVs (2 sets of posts bridged). To compare the two amps, all I need to do is toggle between the audio out options on the Eversolo.  If my more experienced brethren here see anything here that risks blowing something up, please warn me.  Thanks!

I’d like to know too. 
in my case though, there are more sources involved. In addition to streaming it’s  CD and TT.

That’s an interesting device. I like the auto-sensing. Would that still work with the subwoofer in my setup?
I don’t like the price tag so much, though. I understand, it’d be super convenient, probably high quality and super safe, but for now I hope to keep it below $125 for the switching of receivers, if possible. Part of what this switching is meant to do for me is to help me compare and decide if it’s worth keeping both receivers. 
Happy to upgrade that part later in case I decide to keep both. 

I guess if I’d go separates, with a good amp and a versatile preamp, I may be able to have the preamp do a lot of the switching and picking. Things is, I really like my receivers and rather invest in upgrading the main speakers.

I ended up with the Solupeak P2, and I'm pretty happy with it so far.
No noise, no coloring, well-built, sturdy, and good-quality binding posts/plugs.

It's fun to switch between the two receivers feeding the same mains.
