Need some expert advice

Hello all !!
I currently own the foll set up:
Marantz CD 7300
Marantz PM 7200 amp
Dyn 122s

Somehow I am not happy and I am positive it is because of the amp. I think the speakers are far too honest for the bright marantz IMHO.

Anyways I wanted to knock on the doors of you experts to check out the best match for the dyns - what in your opinion is a nice AMP for the 122s. I loved the NAD c372 with the 122s but unfortunately that amp is oop. My budget is around 700-800$. Please let me know your suggestions.
