The 1997 LaserDisc has more high end detail in the audio than the new restoration

A new 4K restoration from a 35mm nitrate print from and a 35mm composite duplicate negative.

Spain Universal Blu-ray is from a very soft DVD-era transfer; caps

Criterion 4K Blu-ray is a new transfer by UCLA, with a bit more high end detail

The earlier transfer used on the Spain Universal Blu-ray and MoC DVD is a bit boomy with boosted bass. The 1999 Criterion DVD uses an even earlier transfer with noticable artifacting and less detail.

Spain Universal Blu-ray has older MoC extra "Kent Jones and Dan Sallitt on Trouble in Paradise" with MoC watermark, and no other extras

4K restoration from Original Camera Negative

The audio on the Kino Lorber Blu-ray comes from a better source than the various DVDs and the previous HD version on streaming. This audio is relatively untampered with, and is likely the best available source as no laserdisc was ever issued.
