Big source improvement using CD player

There is a good video on youtube about the ability to pick the higher res source (mp3 and wave file were used). Pretty interesting.....A young lady was used as the listener and I would assume being young,  she had excellent hearing....in a few instances, she was unable to tell the difference and chose the lower res files...I think she scored 4 out of 6...I’m still looking for the link. Disclaimer: I’m fully content with the sound of my CD’s and associated equipment and have no desire to ever stream anything Hi-res. I do own many MA Recordings which in themselves are quite spectacular.

Found the link....

So let me get this right. You think that an optical output using AT&T high speed glass fiber somehow has an impact on the error rate reading off the mechanism. Well then, there is probably not much use of further discussion. Posting pictures of the Wadia does not make your statement any more correct.

You can’t measure error rate at the output of a CD player, or even a transport for that matter, you have to have access to raw data in the transport (or player) in order to determine error rate. I think there have been some players that showed it over the years, but not a popular features.

"Not an audiophile". Is this your poor attempt at "no true Scottsman" or simply an ad-hom? If you let me know, I can better address your attempted but poorly executed insult. Some of us actually care enough about acoustics and audio to have made both an academic and working career out of it.

p.s. I can’t remember anything from Arnie and Paul w.r.t. error rate testing at the output of a transport (since you can’t really do it, it is already corrected at that point), but I do remember a somewhat questionable "report" on jitter. Arnie really was into this concept of black CDs for a while too.

Iaf you were an audiophile which your clearly not, you would probably know Arnie Nudell (rip) and Paul McGowan did such a thing (you find out what) and showed it to you in a numerical error counter on the display.
Frightening seeing the differences between good and bad transports, that the error correction didn’t get right.
The lowest count I saw was the Wadia T2000 transport using it’s AT&T High Speed"Glass Fiber" optical output connections using expensive indexing fluid on both ends.

Yes I should have a little more specific, for the one that likes to turn things around to make himself look good. Transport "Clock Error" "Speed Error!! is what it measures, not Tracking Errors.
AT&T ST high speed glass fiber optical with indexing fluid helps reduce jitter, what’s with you!!!

And yes to those here, all three above are transport related errors and to how they sound, and why that slot loaded junk is not up to scratch, compared to a good transport. Cheers George

Georgehifi,


You are just digging A bigger and bigger hole. Jitter is not remotely the same as uncorrectable read errors. A buffered and reclocked CD player using a $20 mechanism will be near jitter free within the limits of the interconnect method which has nothing to do with the transport.


I don’t appreciate the constant attempts at personal attacks to cover up for your own lack of knowledge. Based on your own test it should be clear I am the real audiophile and you are not. You called me not a real audiophile based on my perceived lack of knowledge of a test that didn’t even exist. I knew what the tests actually was. Your test for an audiophile not mine.

You are applying 1980s and early 1990s CD architecture operation to newer CD players. As another has noted, where this all started, the Bryston reads into a buffer and reclocks. The mechanism is at that point meaningless to jitter. Your argument is akin to saying that jitter on a streamer must be huge because jitter over an internet connection is enormous. Obviously that is not the case.
