"They have eliminated [CD playback] as a variable," True; but then they try to tell us...

...that hi-rez is no better than CD.

But they have eliminated CD from the equation!

So how can they know?

All they have proven is, that with an apparently crappy system and unqualified subjects, "hi-rez" sounds no better than an unspecified "bottleneck" -- a "bottleneck" that bears Lord-knows-what relation to actual CD, apart from the fact that it has the right "numbers".

But all CD players have the right numbers!

The reported experiments simply leave us hanging.

I can see that I wasn't missing much.

The "CD standard" is good enough, at least under best-case conditions. No efforts were spent establishing margins however so the results are of no engineering value. I suspect that it is just barely "good enough". Clearly you are correct, they inappropriately infer that on all CD based system that mastering will be the limiting factor.

I do appreciate the work they've done especially since it vindicates some of the tentative conclusions that I'd drawn from experience. However the notion that all CD chains are blameless is absurd. Fortunately now that we have capable computers we can reduce or eliminate many of the medium and playback problems so their conclusions are actually far more applicable now than they were when we were stuck with "real time" CD players.

Thanks for letting me see it,

Rick
- "I wasn't missing much." Indeed not. Yet I got challenged for calling it a quick read! nt - clarkjohnsen 10:02:59 09/25/07 (0)

They do appear to be drawing a wider conclusion than their test data supports. Since I don't have access to the damned (at least in this forum) paper I'm forced to rely upon summaries and postings.

If I can summarize the summaries: 16/44 can be good enough. The test was essentially "best case" so indeed it doesn't say that a CD WILL sound good, especially on a given piece of equipment. Although they seem to think it does.

Since this fits my experience I'm not surprised. Even in my modest systems the quality of the mastering, well actually the whole production cycle, is really the biggest variable. The well made ones sound good. And then there are the other 95%. LP's used to have about the same ratio. Reel to reel tapes did better on average.

Again, I'm coming away with the conclusion that 16/44 is barely adequate. So is a 36 Hp Volkswagen, especially if you enjoy observing the fauna and flora while going uphill.
