I would suggest you take your time, enjoy your music on your new rig, and allow yourself to find out what, if anything, you think is lacking in what you're hearing. Amplifiers have characteristic "sounds". When you can tell your audio consultant what you're seeking he'll be better able to make suggestions for auditioning. Then, audition in your home, and trust your ears. There's a wide range of good stuff in the price range you've established, but don't be in a hurry to shop until you know what you're shopping for.

I'm a fan of the AVI Laboratory Series integrated. I haven't listened to it extensively, but I like what I've heard. It has plenty of clean power for your Studios and doesn't break the bank (I believe it goes for about $3600). If you enjoy the Levinson aesthetic, then you'll probably appreciate this piece because it's built like a tank and the fit and finish are excellent. It's also available with a phono module, which would be a cool upgrade if you decide to get into vinyl (Do it). If I had the money, I'd definitely go audition the AVI. I've heard good things about Simaudio, as well.

Happy listening with your new dynamic duo! I'm a Paradigm owner (7se Mk3), so you're alright with me, Rich!

Glad to have you here,

Erik

I went straight to the product recommendation, but you should listen to Clay, too! It'll be easy to find something different from the Arcam, but you might not prefer it. I agree that you should kick back and spend some quality time with your gear (as I'm sure you have), and see if you really find it lacking. If you love it, then keep on loving it! As fun as it is to buy new stuff, it's even better to forge a relationship with what you have. But I'm a sentimental guy, after all.
