Re: [ARSCLIST] Can 78s sound better than LPs?

[Tom Fine <tflists@xxxxxxxxxxxxxxxxxxx>]

As I understand it, due to imperfections in the material and the physical fact that we work in an 
environment with air and gravity present, there cannot be a perfect mirror of a grooved disk. For 
78's let's start with the wax, which can't be perfectly uniform and pure -- just cannot be the case 
in air and gravity. Then you spray it with metal, again with impurities. Thus the grooves get at 
least slightly distorted from the very first transfer. Several more transfers later, you're at a 
stamper and then stamping shellac and later, with microgroove, vinyl. Volumes have been written on 
the impurities inherent to these materials, plus the corners cut to keep costs down and production 
fast. Simple fact is, there's a lot of sonic degradation along the way, theories aside. It's just 
the real world. In theory, digital should be much less lossy due to robust error correction. We all 
know the theory falls apart in too many cases, more due to user error or equipment malfunction than 
actual flaws in theory. The same air and gravity that prevent perfect transfers of grooves also make 
hard drives imperfect, etc, although, again, there is very robust error-correction built into all 
half-decent digital transmission and storage protocols.

Yet, as we well know, grooved disks, with all their imperfections, still play -- sometimes very 
close to how they'd play the day they left the factory -- decades later. Such does not seem to be 
the case with most digital media. And of course there's the whole thing that post-nuclear-holocaust 
ape-man may be able to fashion a Flinstones-like way to play back the boxes of 78's found in the 
wreckage of "Collectorville" whereas those mysterious shiny disks and strange square things that 
contain smaller shiny disks when broken open with a rock don't seem to do anything or make any 
sounds.
