The sighted tests are not worthless. It's the way you listen to things every day ! They are simply worthless when you claim drawing universal conclusions from them: you need controlled environments to draw conclusions.
Nevertheless, they can be a starting point. On the other hand, most AB/X tests (the way they are conducted) leave too many parameters in an "undefined" state. Too many unknown parameters make such tests as worthless as sighted tests, imho. What I'm trying to say, is that it is *very* easy to fool an audience. For both tests : sighted and AB/X. I was reading in Greg Miller's "Perfecting Sound Forever" book (a book about recording history, very interesting, btw) the exact DBT and triple-stimulus test used by CRC when elaborating MP3 compression: nothing to do with usual DBT tests, believe me. And why such a difference ? Because accurate, indisputable results were mandatory when you elaborate an industry standard. ;) -- Themis SB3 - North Star dac 192 - Croft 25Pre and Series 7 power - Sonus Faber Grand Piano Domus ------------------------------------------------------------------------ Themis's Profile: http://forums.slimdevices.com/member.php?userid=14700 View this thread: http://forums.slimdevices.com/showthread.php?t=75040 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
