I know what you're getting at Geoffcin, but Yamaha, and even Sony ARE being truthful...there's nothing factually incorrect about the way they measure and print specs (within tolerances all manufacturers see). Crooked and deceptive maybe, but technically true. But there's a big difference between a Yamaha 120 watt receiver and a Sony 120 watt receiver, and a 120 watt Sony receiver and a 400 watt Boombox...I put the onus on the consumer. You can't blame Yamaha, Denon,etc for using similar methods to Kenwood, Pioneer, and Sony receivers sold in the same stores to show a somewhat comparable spec, that's what a lot of consumers care about, unfortunately. It's just as much a service to them as a disservice.
Hell, I've got a 60 watt Adcom amp that's way more powerful than my 60 watt H/K stereo receiver...is H/K lying too? Does it really matter? They all do it to some point, every industry does, and until this industry agrees on realistic ISO, FCC, or IIRC rules or whatever system, it's a necessary evil.
Way too much focus is put on watts and "high current" so it's probably to be expected.
