Understanding Sample Rate

The key is translating the word "efficient" to it's meaning in the actual DAC: cheap. 

 

Why do you say that?  You don't mean "cheap" as in "cheapness" do you?  Most modern manufacturing and industrial design is very radically "efficent", most certainly the digital revolution to have been what it is because of this single minded approach to efficiency has brought with it the ability for everyone in the first world, and a very large percentage of those in the 2nd and even 3rd worlds to possess computing power unheard of a couple of decades ago...

I just noticed this quote in @sandyk sig:

 

"If you can't hear the difference between an original CD and a copy of your CD,

you might as well give up your career as a tester. ..... Cookie Marenco"

 

Does that mean what I think it means?

 Why would it ?

 My understanding is that she is referring to a physical copy of a CD with identical binary data.

IIRC, Blue Coast still sells high quality " Mastering" CD-Rs which Cookie reports as sounding better, and supplies for CD orders.

MAM Gold CD-Rs also sound better to me than cheaper generic CD-Rs

 

Oh dear.  Is she playing the roll of Ted Denney or does she innocently believe such is the case?

KEF (Muon, Blade and Reference made in UK)

 

 

Are the LS50's part of the Reference line, and thus made in the UK?

 

Lately, I have been thinking of joining the herd and getting a pair of LS50's for the office...

I think she actually believes it. Remember she still uses analogue mixers and tape, digitising only the final master. As far as I know, she has no education in science or engineering, so she's probably simply extrapolating her experience with analogue formats to digital. The quality of analogue tape really does matter, and in her mind, presumably, CDs are just another format subject to the same rules. The truth is that her expertise at recording music (and she seems to be quite good at that) simply doesn't mean much when it comes to the technical side of things.

 

Ted Denney, on the other hand, I can't see being anything but a charlatan. There is no way he doesn't know the technobabble he spouts is gibberish.

 

Yep, I believe there are many fine people in the recording industry who do not understand digital and have a kind of innocent, subjectivised belief.  Some of us objectivists would try to make an example of sorts out of these people but that would be wrong I think.  Her recordings are very good and "natural" to my ears.  I just wish there was more content that I liked.

  Why do you think Telarc, Mobile Fidelity etc. use " Gold" discs. ? It's not just because they can charge more for them, they have better readability, just as Blu Spec CD and SHM formats from Japan do, AND sound a little better with most affordable players. In the case of players such as the expensive Marantz SA11, the differences are still there, but not as pronounced....

 

 

I know you believe this.  It got me thinking, I am down to a cheap commodity LG usb powered/connected disc reader connected to my computer via usb with not a decrapifier in sight.  This thing had to be made in China with parts that cost less than $2. My belief is that, if I ripped the same CD (regular - neither "blue" nor "gold") over and over again for the lifetime of the unit (for argument sake, let's say 1 year of man hours) the checksums would agree >99.5% of the time.  Even in the cases where they would not, the stray bit here or there would be inaudible in all but a handful of rips.

 

Anyone ever actually published the results of such a test?
