Is my Amp OK?


I recently bought brand new speakers - Revel f208. Using them with Cary Audio DMS-500 DAC and Rotel RB-1590.

While I love the sound I am getting, and I am 100% sure the speakers and DAC are great, I feel that I can do better with the Amp. True? If so, what do I get to replace the Rotel RB-1590?

@audioconnection  yes I have. The Parasound Halo P5. I felt it worked better without P5. It sounded like a veil was lifted when removing the Parasound. I just sold the P5 here 
There is no gain mismatch between the DAC and the power amp (both red book standard).
I auditioned the Bryston 4B3, and I was not very impressed. I did not feel that it did much better than my Rotel RB-1590 to justify its double the price. Very similar sound signature. I was able to audition it with my speakers (Revel f208s).

Any opinions on PS Audio BHK 250?

I am also seriously considering the Cary SA-200.2, and was able to borrow one from a friend to try home for a week.
