Running a set of NHT 2.5I

Give it a try....I haven't heard the two together. I ran NHT 2.5i's with an ATI 1505 (125W/channel) and never heard a harsh moment. I suspect the ATI is a far better amp than the amp section of the Yamaha, but your ears will tell you if the Yamaha is doing the job.

Yea I'm afraid that I am going to have to upgrade my amp to get the performance I need out of these.I can still use the yamaha for my home theater stuff if I add a amp right?
