In the March issue of Stereophile magazine, Robert Baird's article, on p. 130, describes the
current reissue of a boxed set of 9 CDs by Mosaic Records: "The Complete Dial Modern 
Jazz Sessions". These famous bop recordings on the Dial label have been reissued before,
and Baird quotes Mosaic's Michael Cuscuna who praises the audio improvements wrought by
mastering engineer Steve Marlowe who performs "bit density processing". Backer says the
result is "pretty dramatic": "he (Steve) goes bit by bit by bit and ferrets everything out.  It's very 
tedious and very time consuming". Backer says re-equalization was performed, and (presumably)
pitch stabilization. Compared to the Savoy Records reissue from 2002, he says the sound has
"a much more three-dimensional presence -- a bigger, rounder sound -- and the high-frequency 
response is greatly improved overall".

I reached out to Steve Marlowe (via Jonathan Horwich) but have not heard back from him.

I've had no experience with DSD, so I'm curious to know what might be meant by "bit density 
processing".  Perhaps others can suggest the answer?
