sonus faber extrime. problem......

i have sonus faber extrime and levinson 23.5 amp,26 preamp.
the sound is far away from hiend.(xlo cabels)why?
Add a Rel sub. It will give you a much more full range and really fatten the sound.
Saki1: How far away from the rear wall are your speakers. You also don't have nearly enough power to wake up the Extrema's. A minimum of 250 watts per channel would be recommended. Awesome speaker by the way!
