Using the system you described, the problem with the sound probably has very
little to do with the MD format. The 530 has crappy converters. What you have
done is take the CD and put it through a digital to analog converter. The
signal then has to be converted from analog back to PCM digital by putting it
through a digital to analog converter. The PCM is processed with ATRAC.
The ATRAC signal is decoded to PCM again and then the digital signal is once
again converted to analog by putting it through a digital to analog converter.
High quality converters alone can cost thousands of dollars. Probably more than
the entire system that you described.
It is impossible to evaluate the sound quality of MD without using much better
equipment and keeping everything digital. If the MD had been copied digitally
(even if the equipment was just so, so), there would be no converter in between
the CD and MD. The only converter would be the final digital to analog (here
the better the converter the better the quality of the sound you would hear).
The better the quality of the MD playback equipment and hence the DAC, the
closer to the original CD the MD would sound.
