Without knowing the equipment you're playing it through, the lack of sonic difference can be attributed to the preamp, amp and/or speakers. It's the synergy thing. From my experiences, the sonic difference of a big ticket component is not as spectacular as the price tag would suggest unless the associated equipment is of equal pedigree. If you slap a set of $2,000 Pirelli's on a Yugo, you can't appreciate what they're capable of as you would if you put them on a Ferrari - just making a point; not a jab at yours or anyone's system ;)
BTW, the Krell unit's age may be showing. The laser sounds like it's out of adjustment.
