TonyM,
I hope you are indeed well! Thanks for the other suggestion to Mdrew, about using the pre-outs for the 2nd zone. (My face is red.) I have an H/K as well but I don't use the Zone 2, nor have I looked at the back panel lately. Good alternative, although I don't like the idea of running long coax lines with low-level signals to other rooms.
And yes, I agree with you on it being simpler to just get a separate amp/receiver on ebay for the second room. I often suggest that to customers who get all fired up about doing whole-house multi-room installations . . ..
By the way, Mdrew, according to a syndicated A/V columnist who loved our Axiom M22ti's, M2i's and M80s, he reported to me that the cheapo Panasonic digital receiver ($200?) will drive our 4-ohm M80ti's with no hassles. I'm dubious, I've never heard the Panasonic, and I'm not endorsing it, but he says it works just fine with the M80s.
Regards,
