Speaker switcher boxes... which one is best?

I didn't realize that Niles had a speaker selector with some sort of protection relay? What triggers it?

Or are you talking about impedance protection (impedance management)? I don't think it "kicks in". Its either active (on) or inactive (off).

Thtats correct, its an impedance protection circuit,
 
The 5 ch 250 watt RELAY SWITCHED ProSolutions system, made in USA way back pre China era...it offers 4 sets of 5 way 12 ga approved binders and each jack load is rated to 250 watts...Not cheap to buy or cheaply made like most todays offerings..its pretty serious studio grade gear..20200531_083830.jpg
 
I hate to be the pessimist, but there is no such thing as a good speaker switch matching box. All of them waste precious watts with poor insertion losses and impedance matching is a big misnomer. You are much better off with two great speakers than trying to use 4 or more speakers of any quality connected together in a single space. If you must have 4 speakers then you should have an amp channel for each speaker. With HT multi channel amps are cheap.
 
Is there any Sound quality difference between in GFS 3 4, or 6?

And is the GFS300 the GFS3? Or a different model?

So how would one go about doing this and having some sort of power/volume control for each amplifier to allow for multi room listening with adjustable volume for each zone, especially if the power amplifiers don't have any kind of gain control? Currently I'm running a c35 McIntosh into a 4b nrb which powers a pair of DCM TF 700s and also powers a perreaux 1150b which is running a pair of DCM TF 500s. Problem is that the Bryston has a significantly lower gain than the perreux making it so that without some external volume control for one or the other aside from the pre amp the two sets of speakers when playing together from their respective amps are producing insanely different volumes. Is there a way to bring some more control to the system?

You may want to insert a preamp in front of the Perreaux. A passive preamp would minimize any signal degradation. You would end up with better SQ than a speaker switch with volume control.

I use an integrated amp to power each pair of speakers in my various rooms. This allows me to adjust volume to match amp gain and speaker sensitivity.
