Integrated Amplifier for Monitor Audio Silver S2 Speakers


Hello to everyone.
I have very modest system and just recently I purchased Monitor Audio Silver S2 speakers.
So far I am using NAD C356, lots of bass but of course not so much details. My room is 17'x13'x9'.
I am listening everything, from uptempo jazz to old disco music. My budget is $2000-$2500.
Thanks in advance on your opinions

First of all, HAPPY THANKSGIVING DAY.
Thank you on your opinion. Very  helpful information. I did replace jumpers with the Cardas dedicated Pre Amp. / Amp. jumpers. They are
available only from Music Direct. The highs improved but of course they didn't improve everything. It's still NAD house sound just slightly more open.
I decided to stretch my budget so now I am considering Hegel H160 but
unfortunately the dealers that carry Hegel don't carry MA speakers. So I would like to see opinions on this pairing, Hegel + MA Silver.
Thanks in advance on your opinions.

Have you looked at the Belles Aria yet? It's $1,900 and blows a Rogue Magnum Cronos away. 
Happy Thanksgiving to you too! I have not heard the Hegel with MA speakers but it is a good amp. Two other good solid state integrated amps in the general price range of the Hegel are the Naim XS 2 and the Rega Elicit r. If your are able to afford any of these three amps, I would ditch my previous Arcam A39 recommendation and look at these instead. Sorry to add complexity rather than reduce it:-/
