Thanks for the answers guys.  I will listen more.

First/quick impressions:  Bad user interface.  Lacking in features.  Sound Quality is great.  Seems as good or better than anything else I've tried.

Thanks again.

According to earlier information the only difference between paid and eval version is the length of play time.
Are there other differences?  My eval version says many things are disable in this version.  I have also heard from a paid customer that the paid version sounds better than eval version.  Is this true?
Can you provide a list of differences between eval and paid?
