The 588 player continues Meridian's refinement of cd player technology. I've owned the 508.20, then the 508.24 and now the 588. Through advances in jitter reduction it better reveals low-level details. I can hear words more clearly than before. The soundstage is more transparent. Across the entire spectrum there is more music revealed. The bass is fine; it is detailed, natural-sounding and does not exagerrate 'bass slam'. I haven't noticed the mid-bass hump another writer mentioned. The highs---extremely revealing; but its possible that there is a slight spectral tilt in this region. I wouldn't call it bright-sounding. Obviously what one hears is dependent on the rest of the system's qualities. Overall I enjoy the new player, consider it an advance over the 508.24 (especially at its lower price), and commend Meridian for continuing to advance the 16 bit format.
