Any interest in measuring a loudspeaker/amplifier A-B switcher?

[wjp007]

Is there a switch that anyone recommends that is set up correctly so as not to damage anything nor impact SQ adversely? I don't care about meters, I want to switch 2 amps, a SS and a tube, with 2-4 sets of speakers. OSD has some stuff but I don't think they have any impedance protection.

Second that. I'm looking for the same. Don't need an VU meter. Right now I have built my own using a pair of DPDT switches, but I would really like a remote. I'm thinking of building something with relays.

It's a shame the Douk VU adds noise into the system.

I am a bit late to the game on this, but here is a review that I did on the VU3, which has some interesting results:
