two hi rez vs redbook train wrecks in progress Reply #175 – 2014-11-13 02:41:03 Quote from: Arnold B. Krueger on 2014-07-30 12:32:40I'm concerned that people are gaming the tests, assisted by the fact that a lot of the monitoring systems they use are chock full of nonlinear distortion and/or are marginal for dynamic range as used.Hi Arny. As you recall, I ran your IM test and found my system to not have such an issue. This was a week before your post here so I am surprised to see your comment yet again about that. Perhaps it was forgotten. Here is that post again: http://www.avsforum.com/forum/91-audio-the...ml#post25974394============QuoteOK, here's my first shot at an IM test.https://www.dropbox.com/s/5xk18jgqmu...st%20tones.zipThere are two files in the zip file - both 2496, both containing the usual keys jangling sound, but at the end are 4 seconds of test tones.(2) Now move on to listening to just the last 4 seconds of the files. The contents of the last 4 seconds of the file should sound like a -30 dB 4 KHz tone (not at all ear splitting), followed by a click, 1 second of silence, a click, 1 second of silence, a click, 1 second of silence, a click and end, whether you listen to the 2496 or the 1644 version. Please report what you hear for both files. Do not change your volume control between the keys jangling ABX listening and an the test tone listening. You do not need to ABX the test tone segments, just do sighted listening and report your subjective impressions.OK, I am finally home and here are my results. Remember though, if anything I say is wrong, I will be blaming it on the dogs!96 Khz: it is as you say.44 KHz: All there except the last click is exceptionally quiet. I had to significantly turn up the volume to hear it.Let's investigate the difference. Here is the last part of the 96 Khz file:.As the soup nazi would say, "no IM distortion for you" in regards to my HP laptop. Thanks as always for your hard work Arny.[/color]===============Back to this HA thread:QuoteTo demonstrate this exposure, I gamed my own system and obtained positive results in an ABX test involving hi rez audio. Trust me the results I posted make $3 bills look like legal tender and of course I say as much as part of the so-called results.http://www.avsforum.com/forum/91-audio-the...ml#post26095274So if this is such a prevalent problem, how come in many years you put this test out there no one had passed it? Do we have more "IM distortions" in our systems now than people did 10 to 20 years ago?
