if testing, you could also try running one amp into each speaker and using the pre-amp to "switch"
this won't test the sound staging and some other things, but costs nothing

High quality Speaker switch box for multiple amps?
Stupid idea, I know. But if I wanted to have 2 or 3 separate amps (NOT running at same time, of course) to choose from with 1 preamp. Is there a switch box (preamp to box, box to multiple amps with a,b, c switch, box to main speakers) that is of high quality and will have very minimal effect on sound? Of course I would keep same brand/model of speaker cable at all points. Just curious

Regarding a line-level switchbox to go between your preamp and the two or three power amps, and assuming that all of the connections involved are single-ended (i.e., RCAs), I’ve had good results with the DB Systems model DBP-2JAU/5 ($110) listed near the top of this page.
I've used it in a couple of different 2-in / 1-out applications, but it
can also be used 1-in / 3-out among other ways. It is similar to the
DBP-2J/5 for which a review and description are linked to, except that
it has gold-plated jacks. For contact information go to their home page. Another possibility, although it costs $359 plus options, is the Decware Zen Switchbox. Good luck. Regards, -- Al |
3 amps is tough. I see this one for two amps into one or two speakers: https://www.amazon.com/TC-7220-Amplifier-Selector-Comparator-Crossover/dp/B00LNOAGZQ I would use this between the preamp and amps (unfortunately, no longer made but can find used): https://www.amazon.com/Niles-Black-FG00002-Auxiliary-Selector/dp/B00006I5J0 |
