I found something interesting. I have two cd players connected to my system now, the ML 5101 and an older Arcam cd72.
The Arcam cd72 has a fuller bass, warmer midrange sound to it. The negative is that there is not as much musical separation.
The ML 5101 has more separation but less bass. The negative is that no matter which PCM setting I use the highs are too hot, to much sizzle which sounds good for about one song, then becomes grating.
