Background on Clarity Vinyl Pressings
In 2008, Classic discovered that demagnetizing black vinyl records leads to better sound in playback. The engineers at Furutech in Japan, makers of a commercial record
demag machine, explained that the carbon black that was added to PVC record pellets contained trace metal that became randomly magnetized and while spinning below an electro-mechanical transducer (phono cartridge) caused electrical distortion inside a cartridge during LP playback. Hence, demagnetizing a black vinyl record dramatically reduces the electrical distortion and leads to more "Clarity" in playback. Michael Hobson, founder of Classic Records reasoned that if the carbon black were removed then the result should be more Clarity in playback. Working closely with the PVC manufacturer Kenan, Classic developed its own proprietary "Clarity Vinyl" devoid of the problems with trace magnetic particles contained in black vinyl formulas. Clarity Vinyl represents the ultimate in vinyl formulations because it is comprised of over 90% percentage of the highest quality co-polymer available - a key component in vinyl pellets used for manufacturing vinyl records. Further, Clarity Vinyl has no carbon black additive, common in vinyl formulas for LP’s. Carbon Black contains trace metals that become magnetized and cause “electrical distortions” in cartridges during playback that smears the sound. By taking out the Carbon Black, Classic Records is able to dramatically reduce the “electrical distortions” and thus bring more “Clarity” to the playback process, providing a more realistic musical experience to the listener and LP enthusiast.A Clarity vinyl pressing on a flat profile die is the absolute ultimate pressing possible and even a step above the JVC UHQR black vinyl pressings. Not to be missed - you can hear the difference!
Background on Classic 200g
Super Vinyl Profile
In 2003, Classic Records launched its now famous
Signature Blue Note Mono reissue series.
As part of that
series Classic developed an "authentic" 200 gram LP profile that
replicated that of an original Blue Note record from the 1950's.
Comparing a test pressing on the new profile versus the same
title on the normal 180 gram pressing it was discovered that the 200
gram version sounded significantly better. The 200 gram pressing
sounded louder, with more definition and solidity of notes across
all frequencies and there was more detail - particularly low level
detail like room or hall sounds, pages being turned, musicians
whispering and automobile sounds outside the studio all became
easier to identify. At first it was speculated inside Classic Records
that the extra weight resulted in the better performance as no one could
come up with a better answer given that the stampers were the
same as well as the vinyl pellets used on both 180g and 200g pressings.
One day, Michael Hobson, the founder of Classic Records was discussing
this unexplainable sonic discovery with the Legendary
Mastering Engineer and Sheffield Records founder, Doug Sax when Doug,
without hesitation stated "Ah Michael you've discovered the difference
in a flat versus conventional profile". Puzzled, Hobson asked
for an explanation which Sax described as going all the way back to
1950's mono pressings and what happened when stereo records came out in
the early 1960's. Sax explained that in the 1950's when mono
records had no vertical modulation (only lateral), pressing
PolyVinylChloride PVC (plastic) records were more easily pressed on
"Flat Profile" dies fitted to the pressing machines since the
grooves on the mono stampers were all the same height (no vertical
modulation). The molten vinyl was able to flow evenly across the
stampers and fill properly during the molding (pressing) of
the record. The problems started when stereo record cutting came into
vogue producing stampers that had variable height grooves sticking up
across the diameter of each stamper. Using the older mono
pressing dies resulted in tremendous problems getting the areas between
grooves of different heights to fill properly - a groove that is in
front of another taller one often got passed over by the flowing molten vinyl
resulting in "non-fill" which was audible and thus a "defective"
record. Pressing plants don't like to press defective records and are
always looking for high pressing yields or a s few rejects as possible.
To
solve the problem, the engineers developed a new pressing die profile
which tapers from the center of the die, flattens in the middle of the
diameter and then tapers again toward the outside of the die. The
new profile was "concave" rather than flat. When you put a flat
stampers onto the concave dies the stampers distort and are no longer
flat - the grooves are no longer perpendicular across the stamper and by
association across a finished vinyl pressing. This new die profile
created "back pressure" on the flowing vinyl and solved the "non-fill"
problem with stereo pressings and resulted in higher yields which was great
for pressing plants and good for record companies who wanted good
prices on pressings. The problem was and still is that the new profile
records don't sound as good as they could because they are not
flat across their profile. Using a micrometer across the diameter of a
1950's mono records reveals that the thickness is virtually the same
across the record's diameter from center label to outer edge but not
so for a newer stereo profile pressing which is convex across its
diameter resulting from the concave profile dies / distorted stampers.
This is the dirty little secret that Classic had rediscovered was known to
old school experts like Doug Sax who founded Sheffield Labs in the
1970's. After the discovery, Classic Records never looked back and all
of its releases and re-pressings after 2003 were on the new 200 gram Flat
Profile dies that were specially made for Classic. Some years later
Classic discovered that the very same profile was used by JVC in Japan
to produce the legendary UHQR pressings for Mobile Fidelity which are
well known to sound better than the conventional Mobile Fidelity
pressings of the same titles - it all makes sense now. The long and the
short of this is that Classic 200g Super Vinyl Profile (Flat Profile)
pressings are as good as it gets for proper playback without groove
distortion from non-flat pressings - Period.
