    If there was a studio in the next room, and wires directly from the mic preamps came directly into your room and into your stereo, would you be able to tell if it was live or recorded? Maybe? Maybe not? ďIs it live, or is it Memorex?Ē, was the old commercials, doing that exact test. Ella would sing a high C and break a wine glass, and the tape would do the same! Not necessarily proving it sounds good? Iíve got a Screaming for Vengeance remaster that if you told me the wires came live from the studio next door, Iíd believe you! Itís just like setting in the studio, as many here have done. But itís all amplified music, except the vocals of course, and there are vocals on that album! Vinyl, of course.

    But it is easy to see on a scope that the signal coming out does not match the signal going in. Harmonic distortions, crossover distortions, etc., etc., and then there is Digital. You take the waveform and chop it into tens of thousands of pieces, and assign a number to it. Then taking those numbers, try to put it back together. And like dragging a rock around in a groove, it really is amazing that it works at all! And doesnít sound like a squealing siren. So, you stitch the square waves back together and it looks like stair cases going up and down, so a filter smooths the edges off until it resembles an analog waveform. Youíve got a nice smooth waveform that sounds great! But, it is not an exact match of the signal that went in. Due to averaging, itís a very close approximation, but not exact.

    The thing about our flawed ears, is that we use the same pair for most of our lives. So however weird the sound is once it reaches the brain, itís what we are used to hearing. So a violin sounds like a violin, and a trumpet sounds like a trumpet.

    Yes it is. Iíve heard very bright, overly detailed stereos before, and itís quite interesting at first, hearing many fine details. But I find that I grow tired of it quickly, I much before a warmer presentation, which most call colored. Distortion is just a part of life, there will never be audio playback without it.

    Audiophile myth. It may not be perfectly exact but it is exact enough that any difference is way beyond the threshold of hearing. In terms of producing the analogue waveform exactly, digital is way beyond vinyl. Orders of magnitude better.

    A properly detailed sound is a product of transparency and system balance should not be a factor.

    Fight fight fight

    Just jesting but James is correct.' Way beyond the threshold of hearing' is just so optimistic.

    I've yet to hear a digital system that gives the same spacial information you can get from vinyl and I've heard some of the best.

    But you making assumptions about the reasons for that which are incorrect. We are not arguing about the outcome (i.e 'the listening') it is the reasons for the outcome where there is disagreement.

    Well, it all depends what you think you are hearing.
    Genuine recorded sounds which for some baffling reason aren't captured by digital, or analog distortion artifacts that you happen to like maybe?
