My MDS-JA20ES allows you to switch the bit length between 24, 20 or 16 bits. This function has always puzzled me. Will this in any way effect the recording and playback of MDs or does this only come into play if using this machine as an external DAC for say, a CD player or DAT deck? Or am I missing the point of this function all together?
