I'm no expert but my experience with a MArantz CD67 (which is a high-jitter player) is that jitter makes everything smooth and blurred. The effect when I added a monarchy DIP and an external DAC was that the DAC alone made almost no difference, but the DIP (the jitter reducer) made everything more focussed and defined ... soundstage, attack of acoustic guitar ... it all came into focus.
So jitter doesn't necessarily sound bad ... I think it gives a warmth to the sound, but it definitely causes great loss of detail.
