I run a Niles selector in the main part of my house, to allow my integrated amp to run and control the volume for four sets of speakers. Works great. But it’s a consumer unit, and can’t accept high-quality speaker cables or banana plugs, etc…
So, in a different, high-end system (down the road), I’d like the ability to switch between two sets of speakers to do A/B testing.
Don’t want both speakers running at the same time, but would love the ability to quickly switch from one to the other for comparisons. (Not sure how detrimental/tricky that is for speakers of different impedances/sensitivities, etc…)
Many I’ve seen have fairly low power limits. Would like something that could handle > 250W/channel.
The TEC TC-7220 above seems like a possible option. It also has ability to run a second amplifier, which I’m not sure I’d need. (Although couldn’t hurt.) Switches look like you can run two sets of speakers at once, but you can’t. It’s an either-or. Which is good.
It has a 200W limit. For the most part, I’m guessing that would be fine, but I envision someday using this with a Hegel H390, which is 2 x 250 W/8Ω.
In this dream scenario, I could see running a pair of Harbeth 40.2’s along side some Magnepan’s.
So, I’d want it to be a high-quality switch, to minimize any sound degradation.
Sounds very expensive, but dreams are free. 
Anyway, any recommendations?
