which amp? too many choices

I have a denon 4802 and am looking to upgrade to an amp with good sound and power. and will have continued use when I upgrade to a surround processor. have looked(reviewed)the ati 1506 the rotel 1095 the mva5 the tagmclaren the cinenova grand5 the proceed etc.. it seems all have some sort of drawbacks in sound at some critical listening area etc..I want alot of power and excellent sound for HT and stereo(I typically use the 5 channel stereo because it sounds better when I'm not directly in front of the speakers)btw I have four def tech 2004tl powered subs and the 2500 center speaker. right now it seems as though I lack midbass and real low frequencies(although the def techs are rated at 17hz. any comments or general help would be most appreciated.thnx
