grainy sounding high end system

Hi, I hope this is the right forum to ask this question. I have a quite decent audio system at home, which consists of Pioneer CLD-98 laserdisc/CD-transport, Bel Canto DAC 1.1, Conrad-Johnson Premier 7b preamplifier, Mark Levinson 333 amplifier and Dunlavy SC-IV speakers. Though this is a "high-end" system on paper, it sounds not very high-end to me: the overall sound has a grainy quality, it has compressed dynamics, the low end is quite lousy and the highs are too prominent. Why is this happening to me? I have invested a lot into this hobby and is this my reward? What could be the reason for the abovementioned grainy sound? Maybe I have to get a better CD-transport, like the TEAC P-30 for example.
