    I will always respect Michael Fremer’s views. In the end he just prefers how vinyl sounds and that is quite fair enough.

    I won’t deny that there’s something deeply special about a well preserved original pressing on a high end rig. I also happen to think that vinyl is a format with high levels of sound coloration which, undeniably, a lot of people simply favor over digital, regardless of its accuracy. Again, perfectly fair opinions in a free society,

    As you rightly observe Mark, digital technically trounces vinyl in all departments, but rather like a modern car will significantly outperform its older versions of the same model, personal taste dictates that some will still prefer what the vintage set of wheels brings to the party.

    My own view is that recent developments in DAC technology are rapidly moving digital to an unquestionably superior level and, what’s even better for the consumer is that said technology can provide incredible sound quality at a fraction of the price of a top of the range turntable, arm and cartridge combination – and all without the constant and time consuming set up rituals that record playing inevitably entails to consistently give of its best.

    Digital files do not suffer from stylus wear, turntable speed variations, accidental damage or environmental contamination. The CD’s I bought in 1983/4 sound identical to what I heard then, albeit that better mastering of re-releases has consigned them to the shelves.
