 I think MD is nice equipment for easy use. This is good system "Walkman" 
listners. 

 And I know new ATRAC IC has "20bit".
 But this "20bit" means "interface bit-bus has 20bit"
 The ATRAC algorithm has time-domain areas coding and floating point 
quantization system. So it is not same liner 20bit PCM resorution. 
 Please record 2 or 3 multi-tones at same time, bitween near frequency.

 By the way, some professional recording engineer said "24bit recording".
 They are using "the 24bit interface A/D converter", so this recording 
means 24bit recording. If it is correct, please using 64bit-bus DSP. 
Please use 64bit output decimation filtering circuit.
 Some people says "Oh!! 64bit recording it is great!" (^o^)/

 But if you round-off 64bit data to CD's 16bit with no dither, you can hear 
great sound.(@_@)?  Please don't use High bit A/Dconverter with no dither.
I do not like q-noise.
