When digital recordings clip, they clip like hell ..." This is totally bogus. If you think that analog systems are designed to clip gracefully (perhaps having S shaped transfer curves) you're wrong. Who would buy an amplifier that reserved 10% of its dynamic range to nonlinear clip handling? Though there is without doubt a certain smoothness when a transister approaches saturation, that region of transition is miniscule compared to the amplitude of the signal. I would venture the opposite argument; with digital recording, any idiot can tell EXACTLY when he is clipping the signal, instead of relying on red zoned VU meters or drifting threshold detecters. If anything, digital recording makes clipping less of a problem since analysis by computers can be brought into play to decide on an optimum recording level. I have had to endure the flames of so called audiophiles stating how digital recordings do not have "presence," etc ... It is this sort of ignorance which I feel is holding back the technology. I recall hearing the same things said of transistor amplifiers a few years back when audiophiles still clung to tubes since they made the music sound "warmer." Perhaps if you snuggled up to the amplifier .... I am beginning to get the suspicion that digital technology will at long last divorce us from these sorts of flames. If all digital players work as they must, there will be no one to advise us of cartridges or record cleaning products and the like. Music recording will finally become a science instead of a wizard's art. Unfortunately, the answers aren't so obvious when it comes to speakers and microphone placement, not to mention the virtues of concert halls. Alas these problems will probably remain on the opinionated side of audio for quite some time. Why the die hards want to fight an advance in the technology which simple signal theory proves to be best method can only be attributed to the fact that it is much easier to convince people you're an expert when there is no way of objectively substanciating your opinions. Well, we don't need experts any more. The technology has been around for the last couple years and I am very tired of being disappointed by low quality records, wear, and accidental damage. Why are we sticking with Edison's method when we know better? Gill Pratt ...alice!gill (usenet) ...gill@mc (arpanet)
