Would you like a track-by-track DR value table for the 2014 remasters to compare against your files?
It sounds like you are looking for a or a detailed discography breakdown of Led Zeppelin’s catalog in FLAC 24-bit format (likely 24/96 or 24/192), covering the period from their 1969 debut through the 2007 release Mothership (or the Song Remains the Same reissue).

If your set is the 2014-2015 "Jimmy Page Remasters" in 24/96 , you have an excellent report. If it is the Mothership 2007 24/48, it is poor. If it is any 24/192 upsampled from CD, it is fake. Would you like a track-by-track DR value table
