Hi, It has been a while since I posted here and that has to do with me. So, don't worry. The question: "Why SACD?" is for me very simple to answer: * it is multichannel (5.1 format which can be seen as an optimum*) * it gets the attention an audiophile would like, that is no loudness war or something like that That's it. Of coarse the technique is quite different and one could talk for hours and hours about potential benefits and other stuff which occurs in the very low level amplitude domain but in practise this is not relevant. The dynamic range of a human being is something like 80 dB or somewhat more and according to this paper in the September issue of the AES (Audibility of a CD-Standard A/D/A Loop Inserted into High-Resolution Audio Playback), it is very questionnable wether the increased bandwidth is necessary at all. I quote: "Conventional wisdom asserts that the wider bandwidth and dynamic range of SACD and DVD-A make them of audibly higher quality than the CD format. A carefully controlled double-blind test with many experienced listeners showed no ability to hear any differences between formats. High-resolution audio discs were still judged to be of superior quality because sound engineers have more freedom to make them that way. There is no evidence that perceived quality has anything to do with additional resolution or bandwidth." One could debate for hours and days about this but the bottom line is that it is apperantly very hard to tell the difference. Otherwise the outcome would be different. Regards, Jacco *) T.
