... you posted a similar comment in a previous thread about vinyl having a wider dynamic range. I've checked the DR Database and I cannot substantiate that claim. Can you provide a few examples of viny releases of the same title having wider dynamic range than the CD?
I don't like being assigned homework, but you could check two of my favorites - Boston's first and S&G's Bookends.
But that's not the best way to read the database, because when a CD does show as having better DR, it's often a special Japanese pressing, SBM or some other release that got extra attention over the common CD you'll get from Amazon. Even then, when compared to a similarly special LP pressing (such as from MFSL or Abbey Road) or an original pressing, the CD often doesn't compare favorably.
My research indicates that at best there is not a good correlation between dynamic range and format.
The best research is work you've done yourself. You can measure dynamic range yourself using your favorite recordings. If you do, you'll probably be surprised.
Generally, however, it looks to me like a later remastering typically has a wider dynamic range on the CD than the vinyl.
I couldn't disagree more. Remasterings are almost always lower DR. Loudness wars.
