I would check out players/dacs with a significant new technology, Minimum Phase or apodising filters. Meridian, Ayre, PS Audio and a few others have players/dacs out with this technology.
These filters eliminate or reduce the pre-ringing or pre-echo that is an artifact of the cd recording process. Pre-ringing is the reverse of echo, you have echoes of sounds before the sound itself.
Pre-ringing is measured in microseconds, so you don't actually hear echoes, but to my ears sound quality is greatly improved when they are removed. If you are trying to avoid harshness, glare or listener fatigue you would be especially interested in this technology.
