Cleaner in what way? The PD170 was already much cleaner than the PD150,
even if both are PCM. In any case audio was quite poor in Sony DV
recorders, and was considered to be much better in Canon XL1s and
Panasonic DVX100.
But you couldn't compare either with an audio recording done on
sole-audio recorders, at least those that record linear PCM at 16bit /
48KHz or more.
Do a simultaneous audio recording in a DV or HDV camera, also recording
that same audio on professional audio recorder. Then play them on a
studio and compare them.
The main problem with MPEG in general are non-linearities distortion.

Not Hi-MD, which is the one I specified as an option, which can record
in linear PCM. It's not compressed.

The system I am proposing has no compression.

If you consider a better audio no real benefit...
Just think of this: why is it that professional audio in video
productions is still recorded double-system?
