Integrated amp upgrade


I'm using a Classé Audio CAP-151 to drive my Thiel CS 3.7s at the moment.
I'm not sure if i should upgrade, anyway if i do so i'm looking for a used integrated amp in the $2K to $3K price range with balanced inputs.
I've seen a Sugden IA4 for $3K and a Musical Fidelity KW 550 for $2,4K but it's not balanced.
If i upgrade it would have to be really worth it otherwise i'd rather keep my CAP-151.
I have someone who would like to buy my CAP-151 for $1,6K.

paraneer there is nothing wrong with my Classe except that i might add a pair of Thiel CS 7.2s to my Thiel collection.
Well now.  That's changes everything.  Your getting lots of good suggestions.
I've had both classe integrated and separates. Still own a cap-101 that I used in my living room that I'm selling. Classe integrateds are nice. I sold my classe separates for my dedicated audio room and went to a Hegel H300 and love it. Much better than the classe cap-101/151 and it includes an internal dac that is comparable or better than the Hegel you have now. If you want to keep your dac, you can use the dac-loop feature of the Hegel h300/360 with your external dac. If you can get $1.6k then I would sell it and that's 1/2 the price of a used Hegel h300
Thanks guys, the thing is that i have to determine if i do a little amp upgrade now or wait until i get the budget to build my ambitious high end system with my Thiels.
End of february i should get a home autidion of a full Ypsilon  system.

There's a listing hear on AG for a pair of Pass 0 mono amps. lis7gccg

I used to have a pair myself. They have tons of power and sound incredible. They had no problem driving my B&W 800's and ProAc Response 3's. It would be hard to find a better amp for the money.

Hegel H200 would be a good upgrade for you, and there is one for sale on US Audio Mart for $2,200.  I've compared H200 to a number of integrated amps, and I find it to be one of the best under $5k.
