| Sep 20, 2012 at 12:09 | comment | added | Pelle ten Cate | I did do a sort of blind test with classical music, on a pair of Genelec 1030 loudspeakers. We listened to one piece, in which every minute the bitrate changed. We knew beforehand which qualities were available (varying from Stereo MP3 96kbps to full 16 bits 44k1 PCM) and we had to determine the order. We did the test with 6 professional engineers, all of which were able to put a lesser quality on the 192kbps than on the 320kbps. While not as reliable as a double blind test, it really suggests there is an audible difference. | |

I, too, was surprised that there wasn't much jumping out at me on the net. So now I guess the key to settle it for the skeptics folks is to find a good ABX trial that's been done. | |
