In any case, the 93 ported over much of the analog board design from the 83SE but still uses the less expensive DAC chip. The 83SE also offers a dedicated stereo analog output which utilizes it's own high-end DAC chip. So for those using stereo analog output exclusively, the 83SE might be the better choice. Again this presumes that your stereo system is of high enough quality to resolve these differences. Most don't fall into that category, and the simple truth is that ALL of these players offer excellent analog audio quality.
