All disc sourced from the 4K restoration use the same solid audio track. Older DVD releases are from a higher generation source with less detail and more hiss.

Criterion is a very nice uptick in detail and resolution. The color grade is very similar, but leans more neutral, reducing the greenish/blueish hues seen on the MoC disc.

Unrestored: Shochiku JP NTSC DVD
Restored: Masters of Cinema UK Blu-ray

The JP DVD track is unfiltered and sounds much more natural and detailed, but suffers from a strong CRT whine and an intermittent low-end hum. The track used on all later restorations is a bit muffled and has overemphasized bass.

Criterion applied additional EQ and roll-off to the restored track, but the audible difference is minimal.

Criterion has a different translation to MoC, but both are solid and trade blows, see comparison.
