Help with integrated amp purchase


I am in market for integrated amp and need help. I am using and Onkyo cd as a transport thru a Monarchy Audio Dac driving a pair of B&W 804n's. There a lot to choose from in my price range. My music taste are mostly rock and am looking for a lively amp not to laid back. I would prefer to have balanced input but not a must. Does any have a thoughts on these amps driving my speakers for my taste:
Cambridge Audio 840a V2
Nad m22
Sim Audio I3 or I5
Primare I-30
Krell 400xi
Plinius 9100

Thanks for your help

If you like open top end with nice uncolored sound I would second Ayer Integrated recommendation although it is very efficient it outputs 60W only (not sure if that is enough for you).

Krell KAV has very good bass but not much else, treble will be artificial and will be overwhelming the rest of the music. Very unbalanced sound suitable mostly for movies.

CAudio 840 is unimpressive in every respect, rolled off on treble and poor soundstage and realism.
Ok Bel Canto does looks like he would be ok. Whats the difference between evo2i and the evo 2 genII that is up for sale here? Thanks for all your help!!!
