Amp for harder music with lots of sounds.

I would suggest the McCormack DNA-500. Read any of the rave reviews on this piece - they are on the money.

I am continually amazed at how good this amp sounds in my system - tight powerful bass, great midrange, sweet highs, very dynamic yet also reveals all the slight nuances in the musical soundstage. Easily one of the best amps around under $10K, and maybe even under $20K. Power to spare, with excellent musicality, layering and lots of air around the instruments. Solid state just doesn't get much better than this without spending LOTS more $$$$$, IMO!

plinius sa 100 or any new plinius if you want slam and power with detail and finesse you cant beat these amps they are the best in the world for the money

I would suggest looking into the new North American Products H-cat mark III. By Roger Paul! It is said to be most amazing at high volume levels. Friends who have them can't stop raving about the realism beyond all other amps.
