Universal players often have the problem of playing SACD extremely well and redbook CD very poorly. You may improve it by modding it, but if your collection is mostly CD, then an outboard DAC may make sense, such as a modded MSB or modded Perpetual Technologies P-3A. These are truly superb DAC's and modding the 2900 will probably not equal them. However, if you do this, I would strongly urge you to get digital mods to the transport and maybe even a superclock2. This will make the difference between sound and music.
