Seriously, suck it!
is it peculiar to this particular example?
if the DR values for CD and vinyl releases are different, it does not necessarily show that they were cut from different masters.

His results are certainly interesting, but I question his conclusions.He knows for sure that the vinyl was cut from the same digital master as the CD, so he concludes that it cannot possibly have more DR. But the TT meter unambiguously shows that the vinyl has a higher peak-to-avg ratio. So in an objective sense, the DR of the vinyl *is* greater. But of course whatever that increased DR is on the vinyl, it certainly is *not* genuine signal that is missing from the CD.
And finally, he states the vinyl cannot possibly sound better than the CD. But in my book, it's entirely plausible that this artificially expanded DR may sound more pleasing. Or less pleasing, of course. The vinyl's extra DR is some kind of distortion, for sure, but it could be euphonic.
In summary, this youtube posting proves nothing - it merely adds a further complication. The plot thickens.EDIT: sorry - it *does* prove one thing: that if the DR values for CD and vinyl releases are different, it does not necessarily show that they were cut from different masters.
How do you think this would play out if a non-dynamic master was used on both the CD and the LP? (e.g. all of my needle drops that have really bricked masters have very similar looking waveforms and are usually within ~1 dB with that meter.) Ian Shepherd is known to engineer decent recordings in a time when most do not. His example was a pretty dynamic CD mix.
Rather interesting experiment done by Ian Shepherd, identifying a likely cause of the DR discrepancy:http://forums.stevehoffman.tv/threads/is-t...11#post-9481216
Why do all (by all I'm speaking from my personal experience thus far as well) the eighties LPs measure almost exactly the same as their CD counterparts? Both are equally dynamic but for some reason always have pretty much the same DR "value" as one another....these records should, in theory, be "scoring" 3-4 dB higher on that meter as well. The records have the same issues of crosstalk, soundstage, etc. that we're taking Ian's word is changing the the "value" of his own recording.
