well, looks like i just bought a set of Emerald Xl's

now for amplifier suggestions. i can stay with what i have or change. i currently have a set of outlaw m200 monoblocks at 200 wpc at 8ohms, i can get a b&k 442 which is slightly more powerful. but, according to the folks at ACI a 20-40 wpc tube amp would also do well.
so, would a better quality amp "sound" better then the outlaws or the b&k(such as rega, naim ect) or a nice tube amp such as a dynaco 35 or 70 or even 120??
thanks!
