Because "listening to the results" tests weren't going their way.has produced an entirely new method for measuring the audible effects of components on sound.
I cannot call BS loudly enough.Simply changing from a stock power cord to a well-made audiophile cord resulted in a 36% reduction in timing errors between the original WAV file and the same file burned on to a CD and played back by a typical high-quality player
Interesting how they name drop him in thereCheck it out:
"Stop looking at the oscilloscope and just listen!"Because "listening to the results" tests weren't going their way.
Actually a computer CD ROM does have a sampling rate, if something gets lost in transmission it will reread and resend. Now if the CD is damaged then you aren't getting by that.Because "listening to the results" tests weren't going their way.

And what's sad is that it's so darn simple to disprove.
A CD player is (normally) 100% accurate. It makes exactly ZERO mistakes.
There may have been a time in audio CD players that wasn't true, but it's always been true for computer CD players, and the audio gear caught up more than a decade ago.
Don't believe me? Try installing a program from a CD-ROM. A single wrong bit will cause a failure.
Can't we get them arrested for such false claims or something?
I will give them a look once their methodology is submitted to a recognized board of EE's and then peer reviewed and their results independently reproduced and verified.What a load of crap. As if engineers don't know how to measure a piece of copper. Now all of the sudden, snake oil, I mean exotic cable vendors have a groundbreaking new way to truly measure audible differences. Note that the people developing this so called "new test method" are NOT even electricians let alone degreed Electrical Engineers. This is the only industry where this nonsense around wire is allowed to flourish.

Good try but they always have an excuse not to accept.Gene,
You should issue a formal challenge to these buffoons and get some national attention. Setup blind and electrical test with yourself and some other engineers. Get these charlatans on national a level. I am sure you could get some honest folks like BlueJeans and others to help out as well.
But have you ever looked at the error rate? If you really want to have fun, drop it to 1x (audio-CD speed) and see how accurate it becomes on first read.Actually a computer CD ROM does have a sampling rate, if something gets lost in transmission it will reread and resend. Now if the CD is damaged then you aren't getting by that.
ALL CD gear has always had error correction. When the Sony players first came out, we would put a wedge of electrical tape over the bottom with the point at the middle and on some, it tracked fine but others had a big problem with it. We cut it to no special angle WRT linear velocity. High speed/high volume manufacturing makes it impossible to catch all defective units before they leave, so error correction was a good way to minimize returns and not cause the format to die an early death. The CD format is called 16 bit but two are parity bits, used for error correction.But have you ever looked at the error rate? If you really want to have fun, drop it to 1x (audio-CD speed) and see how accurate it becomes on first read.
But your correction is well noted. There is an error-correction mechanism in modern CD gear, and your average DVD reader can read CDs accurately at >40x speed.
So a valid detail to point out, but the result on disproving their claim remains the same.
Agreed. And, I will not simply accept "peer review" by selection of peer by the source.. That is not the process.I will give them a look once their methodology is submitted to a recognized board of EE's and then peer reviewed and their results independently reproduced and verified.
I am not holding my breath.
So, is it safe to conclude that their cables are so good that they intentionally create bit errors and correct them?Using my Audio Precision APx585 HDMI Audio Analyzer, I can do what is called a Bit Error Rate (BER) test. If you're transmitting PCM via HDMI, toslink or Coax and run this test, it will give you a BER in terms of %
Every modern Blu-ray, DVD, CD player I've ever tested has always achieved a 0% BER.
There is nothing magical about this. If you're running analog, you simply test SNR, Bandwidth, and distortion. Again this can be done in about 2 minutes using an Audio Analyzer. I've yet to come across an interconnect being a roadblock for measuring good performance in component gear.
The test the snake oil vendors have conjured up with Stereopile is nothing more than a marketing ploy to gain audiophiles attentions and have it discussed on more widely read websites like Audioholics and AVS Forum. My hats off to them I suppose, they found a clever way to garner some extra traffic.
Ah, but according to "them" we are just the non-believers that don't trust our ears.There is nothing magical about this. If you're running analog, you simply test SNR, Bandwidth, and distortion.

That would explain the percentage numbers that had been quoted within the stereophile summary article. Another had questioned the use of percentage drop vs dB drop, you clear that up.Using my Audio Precision APx585 HDMI Audio Analyzer, I can do what is called a Bit Error Rate (BER) test.

Through HDMI,, yes? Two points...first, were they discussing HDMI? Second, have you ever tested the equipment within the list that was provided showing the test protocol, setup, and methodology?? (pffft, what list?)Every modern Blu-ray, DVD, CD player I've ever tested has always achieved a 0% BER.
Agreed.There is nothing magical about this.
It would seem that they were not discussing analog, given the statements of "bit errors". I conclude from that, that they must have been using an external DAC. I also conclude from the discussion, that they have ground loop issues with their special player and special DAC which contributed to their system's inability to correctly transfer digital data without error.If you're running analog, you simply test SNR, Bandwidth, and distortion. Again this can be done in about 2 minutes using an Audio Analyzer.
I have. Hum intrusion, noise intrusion, common occurrence. But clearly explainable using Faraday's law of induction...as you stated, it ain't magic.I've yet to come across an interconnect being a roadblock for measuring good performance in component gear.
Umm, I had the opinion that the vendors did their stuff, presented such, and some guy from stereophile wrote about it. Was Stereophile somehow involved? If so, I missed that point.The test the snake oil vendors have conjured up with Stereopile....snip
Who was it that said "there is no such thing as bad publicity?is nothing more than a marketing ploy to gain audiophiles attentions and have it discussed on more widely read websites like Audioholics and AVS Forum. My hats off to them I suppose, they found a clever way to garner some extra traffic.
No. But it is safe to conclude that the equipment they chose is incapable of transferring digital information without error in "whatever" test setup they used.So, is it safe to conclude that their cables are so good that they intentionally create bit errors and correct them?
