In Reply to: The real poop on Lp composition Vs surface noise or Black is Beautiful, baby! posted by KT88 on August 3, 2005 at 13:20:25:
There was an excellent article in Audio Magazine sometime in the late 70's or early 80's that discussed the sonic characteristics of colors of virgin vinyl. I wish I still had the magazine, but unfortunately, as soon as I left home and went to college, my audio library was discarded before my room was converted to a tv room, *sigh*. Thank goodness I had my TAS issues tucked away with my vinyl!I still remember some main points.
The use of black is actually a compromise. It provides a balance of low surface noise and longevity.Pure clear vinyl has the longest life but has high surface noise, white is allegedy close to the same, while RED was the opposite end of the spectrum, dead silent but brittle by comparison...
I wish I still had the magazine, perhaps someone else in the forum has it?????
Cheers,
Ray

if a record is truly pressed with virgin vinyl regardless of color additive/conditioner, it's transparent. Hold it up to the light and light will shine through! If it doesn't, it's not "virgin".An interesting factoid that also came from that article.
I can remember seemingly useless information from 30 years ago, but I can't even remember what I had for lunch yesterday!
The aging process really sux! :-D-Ray
MoFi, back in the day, used to tout in their ads that you could hold their records up to the light and see through them (you could). I thought it was funny that, when they started making LPs again, their rallying cry was "heavyweight 200g anadisq". No way you could see the light through one of those puppies...
Interesting. I don't think I have any of those.
Do they claim that they are virgin vinyl?You would be surprised at how many records you thought were normal black LP's from the 50's and 60's, then when you shine them up to the light you find out that they are a transluscent deep blood red!
The marketing material described it as "Super Vinyl," produced by JVC in Japan. Claimed that it was durable enough to play repeatedly, without rest. When held up to light, it's a nice amber color.
