Maybe on paper, but realworld, most any test I've seen on Yamaha
from the 2300 to the 2700, they are not competive in pure output power.
In my experience. My 2500 sounds great when in lower volume, but I had to go with an outboard 7 ch amp from Outlaw to get the volume I wanted. My older 740 also lacked the cajuns when it came to brute output. And it's not just my imagination either. I had (gave it to my daughter) Pioneer 1014 that was an absolute brute, at least volume wise, and my son's Onkyo 603 seems to put out more power in every mode vs both the 2500 and the 740 before running out of steam. I actually hooked up and unhooked up all of these one weekend to make sure I wasn't going crazy. The Yamaha, in my "ears" had a better sound, BUT just didn't have the power to drive my Beta's to LOUD, especially in just stereo mode. When I cranked it up, it just plain started to get rough. the Pioneer was stronger, and next was the little Onkyo, but at normal volume, neither of those, IMO sounded as good as the Yamaha, so I decided to get an outboard amp. Once I go 1080P on my display, I'll get rid of both the Yammy and the Outlaw (maybe, might keep the amp just in case) and get me either an Onkyo 905 or a Pioneer 94.
