Hi all,

I've owned excellent Yamaha stereo gear in years gone by as well as some of their early soundfield processors (prior to the era of Dolby Digital 5.1, etc). Unfortunately in recent years, as FredK has pointed out, there have been issues with some models of Yamaha AV receivers (Pioneer, Sony, Onkyo as well) driving the 4-ohm M80 tower speakers. Because of that history with M80 owners, and also because other inexpensive AV or stereo receivers (Denon, Sherwood Newcastle, Harman-Kardon, Outlaw Audio) have no problems with overheating or shut-down with 4-ohm loads like the M80s, I tend to not recommend Yamaha, Onkyo, or Pioneer receivers for use with any 4-ohm speakers. With 8-ohm or 6-ohm speakers, they're fine.

Regards,

Alan
