you done a null test between the two? Another way to put the point I made above is, why don't you just convert your CD collection to 24-bit wavs and then listen to those? Do you hear the improvement then? The point is, campaigning for 24-bit recordings won't change the settings applied by mix and mastering engineers, you've just changed the specifications of the medium. It's like asking an artist to paint on a canvas that's a marginally different shade of white, even though none of the white shows through on the finished painting anyway. It seems that everyone here is becoming fixated with the (small) 24 Bit aspect of the petition. I have now written the petition letter to be more clear and clarify things. Can I just remind every one that the primary focus is on stopping the loudness wars and producing music so that its not dynamically compressed and of the highest possible quality. I am more than happy and trust you the industry professionals as to what the best way of achieving this is. We want this material to be available in various formats, physical CD / Vinyl and electronic files - 16Bit & 24 Bit. The petition is not about data compression in terms of file size(mp3)but the availability of music that has not been dynamically compressed and the avalability to purchase this material, particularly as a download, where the data has not been lossy compressed. I acknowledge your argument that 24 Bit doesn't sound
