A / B Switching


Does anyone have any experience with using a switch to go between speaker pairs?
which unit is best?
concerns over running multiple pairs?

Ive got a pair of B&W 802’s and a Dahlquest DQ-10 (full system).  Mac 2105 amp C 28 preamp.  I’d love to keep both speaker sets in the system, but concerns over signal degradation by the switch or burning up my amp.  Thanks

I don't think so.. Macs are tough.. You need a second amp. If you want to really A/B it right.. The OLD Mac way.. Was A or B or A and B. I like both ways.. It just takes a second amp.. A/B amps switches, are not a great idea.. like you said.. Different impedance matching problems with just a switch.. If the speakers are the same, impedance, that problem is solved, with an A/B switch, BUT the CRAP switch and cables.. LOL Your still stuck with that..

You're better off with the preamp A/B and a second stereo amp.. SQ wise.

Thanks guys for the advice. My listening room isn’t huge.  I may have to end up running the DQ-10’s off a separate system in another, larger, room just based on the space requirements
