if you read the oohashi paper you will see the trouble they have gone to to source ultrasonic music from gamelans special playback equipment special tweeters etc everything checked from source to speaker system meyer moran does not even seek to be a test of ultrasonics it does not pretend to be a test of ultrasonics it does not claim to be a test of ultrasonics if you wish to assert that meyer moran is a test of ultrasonics you will have to formally prove that each and every one of the elements of the chain passes the ultrasonic test so let's check it out source material this is discusssed at it turns out that the vast majority of source discs used by meyer moran were recorded in the s s or s they are cd quality masters and therefore do not have ultrasonic content summary source material fails ultrasonic test the playback equipment used by meyer moran has to be able to reproduce ultrasonics the source equipment used by meyer moran is listed at the principal equipment consisted of an adcom gtp preamp and snell c v speakers you can find the specs for the adcom gtp preamp here the specs are listed as hz to khz fails ultrasonic test the specs for the snell c v speakers are given here they show massive drop off above khz fail summary the playback equipment used by meyer moran cannot reproduce ultrasonics properly grand summary meyer moran is not a test of ultrasonics meyer moran do not claim it is a test of ultrasonics the only person claiming that it is a test of ultrasonics is you it is your own original research which is a violation of the wiki original research provisions worse your claim is completely flawed and erroneous at every level of the chain from source material through to speakers i'll leave this up for a day or so for some discussion if you cannot prove your original claims then out it goes p s your lehrman reference is just a quote of meyer moran it also has absolutely nothing to do with hypersonic or ultrasonics you might want to take this to the cd advocacy page but it has nothing to do with the ultrasonic effect out it goes
