NADs are known to have muscle power as an amp.....given that you have these speakers and sub, you need to see the amp which supports the connectivity....
Besides NAD, you could possibly also look at Denons / Marantz / HK etc....
i used to own the nad 275 power amp + a nad pre. their sound signature hasnt changed much with the new models. big bass though a little laid back (read not tight). sweet highs and the silky mids. vocals are one of the best you hear. its a little on the warmer side which makes it lacking a bit when you listen to rock etc. but brilliant for folk music, classical, jazz etc.
whats the rest of your setup. and what sort of music do you listen to
i upgraded to the acoustic portrait amp and its better than the nad. and you pay less for it as well. its a lot more accurate in its presentation
