Bryan, we use a lot of niles equipment, both speaker switching and remote control, and all work well. we also sometimes combine with elanhome systems and channel plus product as well.
it just depends on what you want to control.

have you run signal wire to any locations or do you just have speaker wire? since the rvl6 is remote, this is a consideration?

let me know some more details on what you have wired and I'll be happy to make more specific recommendations.
