There are two classes of players that are popular, those that are extremely expensive and those that roll-off the highs or at least limit the HF dynamics.
Frankly, if you want to get rid of the sibilance and harshness, you need a better DAC, which you will never get in any player except the ridiculously expensive ones (>$10K). You are better off to get your transport modified to reduce jitter and get a modified DAC, such as the Perpetual Technologies P-3A.
