Sherwood Newcastle has a well-deserved reputation for making quality components. Unless somebody has discovered a design flaw in one or the other, I would assume that the two units are equally capable, as far as CD playback is concerned.
Yohanboy, it sounds like you need comments from somebody who has owned one or both players. Thus, your question might be better phrased: "Does anyone who has experience with either or both of these players have any comments to offer regarding their relative sound quality?"
When you ask a question like you asked, you're likely to get more general responses from folks who think you might be asking if CD players sound different from one another, etc. It sounds like you're really asking a different question.
As another suggestion, you might try writing Sherwood and asking them for their thoughts, or whether they could refer you to any reviews, etc. Not that you should necessarily accept anything they say at face value, but I recall one time having difficulty finding reviews of a particular component, and the manufacturer answered some of my questions and directed me to some outside information on the product (which I ended up not purchasing in the end).
P.S. I would not put too much stock in the fact that one player is heavier.
