    CD vs High res - there is a difference

     If you study the scientific data about the sensitivity of the human ear to noise and distortion, as well as the relatively  large amounts of noise and distortion in commercial recordings, you will probably reach the conclusion that the excellent performance of modern electronics is generally...

    CD vs High res - there is a difference

      No prophecy here, its already documented fact. First case of this I saw in a published test related to the Pono, but I have seen it happen since on my test bench with another commercial device. Designers are using those configuration options that I have documented!

    I wish HD-audio albums would hurry up!

     I guess your personal choice is to believe everything you read on the internet. Not me! The most likely explanation for most of it is that it is based on sighted evaluations which are well known among scientists who study such things to be grossly invalid.

      Please review http://archimago.blogspot.com/2015/11/measurements-windows-10-audio-stack.html if you have not already done so.

    CD vs High res - there is a difference

      I've done a number ABX tests with younger ears and filters that were -3 dB @ 20 KHz and -1 dB @ 10 KHz with positive (statistically significiant @ 99% confidence)  results, no cherry picking of program material or test system required.

    Why 24 bit audio and anything over 48k is not only worthless, but bad for music.

      Unlike you Kieth my designing of test protocols which is very extensive, includes audio testing. Furthermore in the process of developing audio test protocols I devised ABX which is the surely the most discussed testing procedure in the history of audio.   The idea that if you're trying to...

    Why 24 bit audio and anything over 48k is not only worthless, but bad for music.

      Under what conditions? Under every condition that we had the resources to test at the time of the review (1986) to test.  There was no cherry picking of people, equipment or media except for maximum sensitivity to small differences, and players that might be expected to sound different or...

    Why 24 bit audio and anything over 48k is not only worthless, but bad for music.

      Without some more complete references, I can't tell what the above means, or even be sure that it was directed to me.

    CD vs High res - there is a difference

      If one studies http://www.akm.com/akm/en/file/datasheet/AK4396VF.pdf  page 11 and 12 one finds that the AK4396 has standard features that are easy enough to implement for introducing high frequency losses that can reasonably be expected to be reliably audible.  It has other similarly easily...

    Why 24 bit audio and anything over 48k is not only worthless, but bad for music.

      DACs used in consumer digital player have been tested with DBTs and shown to be sonically transparent ever since the second generation of CD players in the mid-1980s:     "Masters, Ian G. and Clark, D. L., "Do All CD Players Sound the Same?", Stereo Review, pp.50-57 (January 1986)   Thus...

    Why 24 bit audio and anything over 48k is not only worthless, but bad for music.

      Interesting  attempt to invalidate what many find to still be good evidence and still a good read. BTW, it can be found at https://xiph.org/~xiphmont/demo/neil-young.html   The stair step content of the article (under "Sampling fallacies and misconceptions)" is obviously there to show the...

    Why 24 bit audio and anything over 48k is not only worthless, but bad for music.

      It is my contention that the demo above will never happen because producing it requires way too much work and too much altruism. I won't say that in general the people who promote the overpriced gear listed know for sure that they would fail, but I do think that their doubts have probably...

    Amps and Basic Measurements

      The fact is that amps based on fairly ordinary tubes have been routinely used at RF frequencies up to 150 MHz and beyond. For example the 12AT7 which was widely used in audio was also widely used as the RF amplifier in FM tuners.     It is true that tubed audio amps tended to have limited...

    Why 24 bit audio and anything over 48k is not only worthless, but bad for music.

      If one studies the issue at all, such as reading the article and some well known discussion of it,  one finds that the following is a litany of false claims:   "The fact that a number of audiophiles were unable to distinguish between two formats in an ABX test, using (unspecified) content...

    how to sound science, a messy attempt.

      Two words: Sighted evaluation.
