I’m running into issues with A/B Testing and maybe my receiver just wont support it (TSR-7850), but I think there could be some good discussion on this topic. I currently have my AVR with line out to a power amp (Mitsubishi DA-A10DC) that does have an A/B selector.

​

What I would like is to EQ each set with the same woofer and switch between the two. I’m working with some Allison CD-9 (Sensitivity 90dB) vs KEF LS50 Meta (85dB). I suppose I could have someone do the switching for me and adjust volume for each. I’m guessing I need a receiver that I can easily switch zones on and set each one up like for like.

​

Anyways, do you have a good process? For the record, I think I still like my Allison speakers better, might need to adjust some positions though.
