I would highly recommend a Sony XB930E - If you can find one. I bought it at a runout very cheaply. But this is the best CD player I ever had and belive me I have owned a few. CD players have always given me a headache on longterm listening - sounds harsh. THe only exception to this rule was an Akai (when they were still in the hifi buisness)I bought about 15 years ago and foolishly gave away.

The XB 930 has a digital filter that can be changed. it has 4 settings. The filter number 1 is the best by far and gives a rather analoguge like smooth sound NoT harsh at all !!. The standard filter is not that different from most other CD players but of better quality tahn most.
It is built like a tank and has a rather cute metal disk that has to be used to clamp the CD - some what like a Naim CD player. The sound of this player is distinctly different (when on filter settings other than standard) and it is the best by far and I am talking about CD players costing thousands of dollars. Going by the superb build quality that you can never find at this price point, it should last you a life time
