I find this work very interesting. For a long time I have believed that the present metods for measuring audio performance were very lacking. They are all based on sine wave steady state measurements. This worked well enough for showing harmonic distortion products and was very useful in advancing audio design. But music is not sine waves. It is not repetative. There is no method I know of that adequately measures the true performance of a system's performance to music. The introduction of TIM and other intermodulation distortion measurement techniques was a huge step in the right direction, but still rely on steady state sine wave stimulus. I hope this type of measurement technique continues to improve and become more widely used. If the alorithm is improved to adequately seperate time errors and amplitude errors, I think it might improve our understanding of audio design significantly. I don't want to imply that just because this work shows differences when using cable supports or "better" mains cables, that I would run out and snap up all of the products, but I definitely find the results interesting and look forward to more reports like this. Of course this does nothing to address what is "audible". This is a much more subjective question, and each person wll have to decide this on his/her own. But improving the methods we use to measure the performance of audio equipment is a very good thing in my opinion. How you accept (or not) the information is up to you. But for me, I prefer to have all of the information, and sort it out as I see fit. I would love to see this expanded to a step earlier in the process. They take the CD file as the starting point and apply the techniques to the player and amplifier used for playback. I'd love to see the raw audio (analog) digitized by the measurement ADCs, then compare that to the result after subjecting it to the process that makes it a redbook CD, which is then played back. How close does this get to the original?
