The effects of an external amp will depend much more on your speakers and your listening room than on the source. My B&W 704 speakers have the same 90 dB sensitivity as your CM10 speakers, and they play as loudly as I'd like in my well-damped 12x13 room with the volume (after Audyssey calibration) at -25 to -22 dB. If you have a powered sub, the internal amps in your x4000 are hardly breaking a sweat even at very loud volumes.
I use an external Carver 200 wpc amp for these speakers, and I find that they give me a little more dynamic "punch" in the climaxes. But it's not a huge difference, and I wouldn't be using an external amp if I didn't already own one.
