First time around only got 1 out of 6 but all the others I chose were the 320 wav using cheap over the ear headphones straight out of my desktop. The second time I got 3 out of 6 correct using the same headphones but using a cheap DAC and chose the 320 wav files for the other 3. I would love to do the test with my higher quality DAC and my higher quality over the ear headphones but I do not have access to them at this time. I rip all my CD's to FLAC at home and then convert to 192kH MP3 to load on to my phone. The only time I listen to the FLAC is when I use my higher quality DAC and higher quality headphones. I have bought 3 albums from high definition websites and on only one (Van Morrison Astral Weeks) can I tell the difference between the high definition version and the CD version in blind testing. Given this I have not purchased more high definition CD's.
