I'm using the Sunfire amp to drive the woofers, and 2 channels of a Sunfire Cinema Grand to drive the mid/tweet array in my NHT 3.3's, and a Balanced Audio Design VK-3i preamp. Sweeeeet! Too much power is my creed. But I think given the investment you've made in your components, a speaker upgrade might be in order. Something to throw down a little more LF output. Maybe a powered subwoofer would be in order? Your 2.5i's are quite worthy (those are my surround speakers), but do lack bass impact.
BEST SPEAKER TO MATCH..
This is probably the first time that a female trying hard to be in audio circa, is asking desperately of what speaker I can match with my Sunfire AMP (300 watts per channel and Sunfire tube pre-amp with kimber hero IC and kimber 8tc speaker cable.
Right now I am using NHT 2.5i and my boyfriend (who introduce me to this craze)is telling me all the time that my set up did not match the performance of my amp and pre-amp....pleeease help...
