My system -- NAD 325BEE integrated amp, NAD 525BEE CD player, Epos ELS-3 speakers -- sounds great most of the time with most music, but I've noticed that the sound sometimes becomes muddy and confused when playing complex rock or pop music at high volumes. I don't want to make too much of this. I most often listen to jazz played at moderate levels, and for that music the system produces clear sound that is extremely involving. Still, I'm curious to know what's going on.
I live in a loft apartment, so the listening space lacks ideal geometry, and I suppose that could be the cause. It's also true that the NAD isn't the most powerful integrated amp out there, and the speakers aren't the most sensitive, so another possibility is that the 325BEE lacks the horses to drive the Epos speakers at these levels.
For all that, my guess is that I'm just asking for too much from those tiny little Epos speakers. Thoughts?
