Help with amp selection

I'm looking to upgrade my Denon 3300 with seperate amps and was wondering if someone could give me a few suggestions.

My current setup consists of Boston Acoustics Lynnfield 300L as front speakers in a 5.1 setup with Boston VR40's in the rear and a subwoofer crossed over with the Denon's bass management at 80Hz. I'm mainly a home theater guy, but always stuck to the philosophy that if it sounds better with music it will home theater as well. Not a big fan of the THX standard other than cinema re-eq. I also use this system for 2-channel music as well.

I recently accquired the 300L's and they are fairly in efficient 85db I believe. I used to own an Aragon 2004MKII many years ago but had to sell when the wife and kids came along. I was thinking of trying to find some 2004's to hook up to the system, but wondered if anyone could recommend alternate brands. The Boston's can be a bit shrill in the highs, so I'm looking for an amp that has a warmer sound to it. I don't have much of an opportunity to demo amplifiers where I live. The nearest big city is Indianapolis and it's about 60-70 miles from smalltown USA. How would someone classify the Aragon's sound?

Any suggestions would be greatly appreciated and I look forward to participating and learning from this forum.
