A reserve of enormous power and control while (to sizzle MP3 320kbps they must pre-amplifier to maximum and push the volume up).
A good response in all frequency although we would have liked slightly more present mediums and a descent into the lower most important (audible to about 40Hz).
Only downsides: the really big box (larger in area than my PC) and the absence of a wireless remote that destines this kit to a PC.
