Irrespective of what you think, EVERY review of Stereophile is always backed up by a technical analysis of the product.
Yes, anyone can. But does that anyone have the knowledge and experience of John Atkinson, Michael Fremer, Robert Harley, and others? Even more than the knowledge, do that anyone have the access and experience of having dealt with and reviewed thousands of equipment. John has seen, met and spoken to more audio designers than you have even heard of, let alone met. He has reviewed equipment you have not heard of and will most probably never have the opportunity to even see in your life.
One of the first things I do in life is to accept with humility when I meet someone who is more knowledgeable. I have always found such people to be not only knowledgeable, but also have the humility to share their knowledge with you if asked properly.
Coming from a country where a Guru is revered, I find the arrogance and non-acceptance of better knowledge a bit surprising.
Cheers
Did I speak anything about Equipment - where I definitely have less knowledge and experience than the esteemed Sterophile camraderie?
I was critical about their measurements not because they don't perform measurements - but because they discard it when they wish to promote something. Especially in the case where the measurements are not exceptional, but the product is "supposed" to be. Please have a look at their archives of speakers - the frequency responses and the waterfall plots.
Their measurements are not commensurate with the audio commentary in few cases.
Quite frankly, the fact that Stereophile staff is more experienced in sound engg, production, reprodcution, or anything else has got nothing to do with whether what they write is wrong or right. They can have any number of reasons to project wrong information (mistakes/errors also included)
Anyway as I said, I created a 2048 Hz test tone - sine wave.
Taken the frequency response table* of it.
Converted the test tone to V0 mp3 (VBR with about 256 kbps bitrate) - taken the frequency response table.
Converted the orginal test tone to V5 mp3 (VBR with abour 130 kbps) - again taken the frequency response table.
I have enclosed the three here in the zip file. I have also taken the liberty of showing only 1000-4000 Hz spectrum.
Observations:
1. The test signal is -1 dB
2. The noise floor is about -140 dB
3. With mp3 v0 the noise floor is about -100 dB
4. mp3 v5 noise floor is about -100 dB
Now YES there is a difference of 40 dB. But has anyone even tried to hear the -100 dB levels? Our hearing usually fails at about -72 dB.
In any case this is quiet different from what stereophile presented (-80 dB noise for mp3).
Another case where Stereophile was WRONG was that mp3 at higher bitrate will have lower noise floor. (it doesn't)
Anyway, since the people on this thread are more interested in showing respect and seeking respect, mathematics and science WILL take a back seat (as it has always taken in India - no progress after Aryabhat and Susruta). Sorry for ruining the audio bliss and negative notions ...
*Frequency response was created using Audacity and BlackmanHarris window
(
Window function - Wikipedia, the free encyclopedia) - and therefore you see few dBs around the 2048 Hz. It doesn't mean that there are other frequencies also around 2048 Hz, its just the result of windowing function.
