I sold them both. As far as power performance goes, I already had a mono amp for my center & a separate two channel amp for my mains. The NAD is powering the surrounds (4ohm) & there's never been a hint of an issue. One of these days just for giggles I'll have to disconnect my separate amps & run everything off the NAD just to confirm how powerful it is.
I never heard the Yammie so I can't offer an opinion.
I've owned Yamaha, Denon, Pioneer, and now finally finished with NAD separates.
I sell Denon, Pioneer, and Nad at my store. I always make sure that a demo is done with a customer on a number of difference brands before I even give my opinion on them (and I am biased towards NAD). But regardless of wattage and 80watt NAD will trounce a 120-150watt Yamaha any day of the week (maybe except the Z11). The current (amperage) difference between the brands is significantly different. And the NADs ablility to dig down to 2 ohms plays a huge part in its ability to play distortion free at high volumes.
Remember, impedance varies with frequency. It may be rare for speaker to dip down to 2 ohms. But they do, and your typical receiver from Denon, Onkyo, Pio, Yammy, will produce compression and distortion at high levels because of it.
I have done a side by side demo with the same material (demo cd I use at work) with a T765 connected to B&W CM7s, and a Denon AVR4310 connected to CM7s. There is this one passage in track 2 (I believe) of Kiss My Axe, and when the bass hits, the CM7s connected to the 4310 distort/compress while the CM7s connected to the "less powerfull" T765, is clean and clear.
