You didn't hear it here.


Dr.Aix strikes again.

"Additionally, the guru behind MQA — Robert Stuart — wrote in another AES paper, “... there exist audible signals that cannot be encoded transparently by a standard CD; and second, an audio chain used for such experiments must be capable of high-fidelity reproduction.” His position is untenable if the results of my survey are true. If real world audiophiles cannot hear a difference then there is no audible difference."

I read a recent Alon Wolf (Magico) interview where he says they use Redbook standard digital to test his speakers, so there's that. Great recordings in any format can, and do, sound great...I've hear MQA playback and like I said, it's good if it's good, but well recorded CDs will sound great on a well sorted rig...I can hear every detail in great recordings on Redbook CDs using a great DAC, noise eliminating power supplies, and clean ears. 
Didn't have to refute. This study was public enough that you COULD have had some input. That's all I said.
You can pick on this one without citing?
Don't think you refuted my statement if you intended to, "He does not prove conclusively that some people will not be able to detect a difference, at least if I am interpreting his study correctly. "   There are experiments that have shown ability to detect slightly beyond Redbook, experiment that were tighter controlled.

No link.
It was pulled from an email that went out to all participants. You found it easily enough.Dr. Waldrep was open to input last year when he designed the challenge if you wanted to "prove" anything to/for yourself, you COULD have showed that you can hear the difference better than chance guesses.Most didn't even though they thought they could, going in.

Now you are just a Monday quarterback.
Mark produces and sells HiRez recordings so he has reverse incentive for the findings.

Really should cite where this was pulled from:

Keep in mind his person was previously a proponent of high-res formats.

I think the conclusion he made needs to be clarified. "The Average person cannot tell the difference between HD and CD". That "Average" person includes audiophiles, recording engineers, etc.  He does not prove conclusively that some people will not be able to detect a difference, at least if I am interpreting his study correctly.  Research over the years has indicated the likelihood of the ability of some people (not old audiophiles), being able to detect slightly beyond Redbook sample rates/bit-depth (with/without dithering).

If you mention CD, Mr. Pebbles will pollute the thread with posts about problems that don't exist that only he can solve. Maybe if you send him $25 he will leave your thread alone?
I dunno
I see claims not proofs.
Scientific you are not 
Besides that is totally off topic.
I dunno about all that, it doesn’t sound true. But what is true is that signals that ARE encoded in the CD cannot be played back through virtually all CD players. And I can prove it! For example, much more information will be heard when the CD player is isolated from low frequency vibration. But it doesn’t stop there, no siree, Bob,
