Mastering work is not done at 16/44. Final mastering of the physical discs was done for CD printing at the appropriate rates. A look at how much information above a certain level is present on a file by file basis for the 24/192 SD card version would be a deciding factor. Both versions actually. A mix of tape and vinyl from various sources was used for this set. If you have not seen the following video it might impact your decision making.
Are you aware of the Divina Records offerings?
Thanks. Yes found some interesting comments on other sites about this particular remastering.
