Given all the effort involved to make and sequence a recording of an LP, it's worth the added step to first clean the LP and get rid of as many of those clicks and pops as possible. For me that means ultrasonic cleaning followed by a VPI 16.5.
vinyl versus digital redux
Has anyone compared the sound of vinyl with the sound of digital converted from a vinyl intermediary ?
I am referring to 'rips' of vinyl made with high end, high quality vinyl playback systems, with
conversion to high resolution digital.
I find it nearly impossible to distinguish the two results.
The digital rip of a vinyl record sounds identical...or very nearly so...to direct playback of the vinyl.
If one has 'experienced' the foregoing, one might question why digital made without the intermediary of vinyl sounds so different from vinyl. A detective story ?
We are talking about vinyl made by ADC (analog to digital conversion) of an amplified microphone signal and re-conversion to analog for output to the record cutting lathe, or from analog tape recording of an amplified microphone signal, and then....as above...via ADCl and back to analog for output to the cutting lathe.
Of course vinyl can be and is 'cut' (pressings made from 'stamper' copies the 'master' cut in lacquer) without digital intermediary. Such practice is apparently uncommon, and ?? identified as such by the 'label' (production)
Has anyone compared vinyl and high resolution digital (downloads) albums offered by the same 'label' of the same performance ? Granted, digital versus vinyl difference should diminish with higher digital resolution. Sound waves are sine waves....air waves do not 'travel' in digital bits. A digital signal cannot be more than an approximation of a sine wave, but a closer approximation as potential digital resolution (equating to bit depth times sampling frequency) increases.
If vinyl and digital well made from vinyl intermediary sound almost identical, and If vinyl and digital not made via vinyl intermediary sound quite different, what is the source of this difference ?
Could it reside....I'll skip the sound processing stages (including RIAA equalization)...in the electro-mechanical process imparting the signal to the vinyl groove ?
Is there analogy with speaker cone material and the need for a degree of self-damping ?
Were self-damping not to some extent desirable, would not all speaker cones, from tweeter to sub-woofer, be made of materials where stiffness to weight ratio was of sole importance ?
Thanks for any comments.
