What Do Records Sound Like? |

We were having dinner with our friend Helen
the other week. (Should I tell you about
Wahid’s incomparable lamb skewers, his basmati
rice and homemade bread, the obscure spices
that go into the marinade and rice that no
amount of friendly persuasion will get him to
reveal?) I was fascinating the table with
tales of my recent adventures hunting old
vinyl at Goodwill and Salvation Army stores.
Out of the blue she asked a question which, I
suppose, should not have but did surprise me,
What do records sound like?
My relationship with vinyl was always
love-hate. Records sounded good enough, if
your rig was capable of tracking loud
pianoforte passages without the stylus dancing
around in the groove, leaving behind permanent
damage, but absolutely nothing I ever did kept
my records from acquiring pops and clicks and
even the occasional scratch. In fact it almost
seemed the harder I tried, the worse it got.
Not special proprietary inner sleeves, not
anti-static sprays (I knew how to make the
stuff for a tiny fraction of retail cost), not
preservatives, not carbon fiber brushes or
special cleaning fluids. And the rig I had in
those days, unlike that I now own, didn’t
effortlessly move the inevitable noises to
either side of the soundstage, but tended to
leave them front and center for the highest
possible annoyance factor. There is in life
nothing quite like the feeling of having
pampered a disc with the very best of jackets
and fluids only to discover a new scratch, or
some new pops and clicks, when you go to play
the thing. I used to wonder if other
audiophiles had this problem or if it was only
me, like those people who put on a wristwatch
and it stops running?
These days, the availability of an alternative
to vinyl records, those little silver discs
with the 1’s and 0’s, enables a degree of
tolerance and nonchalance to its foibles
impossible twenty years ago when the big
black, wobbly discs were the only game in
town.
From a technical standpoint, vinyl is inferior
to CDs. Signal to noise ratio, channel
separation, distortion, frequency response,
dynamic range: CDs have vinyl beat in all
these categories. And no tracking error.
(Let’s us not, for God’s sake, hear gainsay
from the peanut gallery about frequency
response. Virtually all vinyl recordings are
rolled off well before the perfectly flat
upper limit of CDs. And as for reactionary
claims of “hearing” the 1’s and 0’s, or the
impossibility of quantified data recreating a
continuous (analog) signal, I can only suggest
they take it up with Mr. Nyquist.)
And the fact is you can go down to the bargain
room of your local high-end store and buy an
NAD CD player for $250 that won’t sound half
bad. But in order to play vinyl decently you
have to lay out a lot more money. And to play
vinyl superlatively you’ve got to lay out a
small fortune. And that’s not taking into
account the cost of a phono stage (since most
preamplifiers these days lack one) and a fancy
step-up transformer for that low-output moving
coil cartridge. In my experience it is patent
that the financial point of diminishing
returns for a CD front end is much lower than
that for a vinyl front end. Why you can put
together a damned good CD-based stereo system
for the cost of a great phono cartridge!
But I have a special love for record players.
It’s always struck me as a near miracle that
they work at all, let alone as well as they
do. The idea of a little piece of meticulously
formed diamond on the end of a hollow
cantilever made of some proprietary alloy of
boron and beryllium or whatever, bouncing back
and forth in a soft plastic concentric groove
containing microscopically fine variations,
producing beautiful music, has always rather
amazed me. And the problems involved! A
constant rotational speed (unlike CDs) means
the microscopic fineness of the physical data
increases as the tonearm moves inward,
exacerbating the inherent problem of
controlling the continuous
acceleration/deceleration of the stylus. The
cantilever holding the stylus must accurately
transmit the stylus motion to the inside of
the cartridge without adding standing waves or
resonance of its own. Inside the cartridge are
a pair of magnets or coils which present
acceleration/deceleration problems of their
own. And any vibration that is coupled to the
cartridge body must be damped, otherwise some
frequencies will travel through the tonearm to
the plinth and to the spindle and platter and
back to the record as out of phase feedback.
While other frequencies may reflect back from
a discontinuity on the tonearm body or
bearing, reentering the cartridge body.
Moreover, the motion of the stylus in the
grooves generates vibrations that travel in
all directions through the vinyl, and these
too must be damped or they will bounce back,
or return by way of the spindle, plinth and
tonearm. The massive platters and costly
bearings on expensive turntables do more than
help quietly maintain constant speed: they are
coupled to the vinyl record with a clamp to
help absorb these very vibrations. And of
course a radial tonearm would have to be
infinitely long to eliminate tracking error.
Have I left out anything?
As one might expect, the turntable/tonearm/cartridge
is one area of audiophilia where money spent
tends to be clearly audible. I am not in the
least convinced my Accuphase DP90 sounds
“better” than a PS Audio Lambda (particularly
when used with a reclocking DAC that’s
theoretically immune to incoming jitter above
2Hz). But the vinyl fanatics who invest
$14,000 in a VPI Industries TNT HR-X and a
Koetsu Rosewood Signature cartridge tend to
get commensurate sonic excellence.
My kit is not in that league: a stock Rega
Planar 3 with a stock RB300 and a Benz Glider.
Total cost: considerably less, I imagine, than
retipping the above mentioned Koetsu!
But, to return to my friend’s question, what
do records sound like?
Magnificent, that’s what. My library of vinyl
is pretty small and, like my much larger CD
library, consists of almost all classical
music. So my claims for the “typical” sound of
records are statistically invalid. But my
sense of that sound, neutrality, presence,
body and, especially, superlative imaging, is
shared by many others. Why should that be? Why
should a medium technically inferior to CDs in
every respect, (often) sound better than CDs
(typically) do?
I know a guy who not only prefers vinyl, he
prefers monaural. He is a classical
clarinetist and feels that that combination
sounds closer to live music. Oh yes,
live music: live music is, we should remind
ourselves, what high fidelity sound was
originally about. And how many of us have
regular exposure to live music? For most of
us, when we sit down between a pair of
monoliths and smile because it sounds just
like a violin, we are in truth relying on a
very distant memory of how a violin actually
sounds. Maybe some of us have never even heard
one. But then again, my audio mentor, who does
listen to live music frequently in his concert
attending and audio engineering activities,
was visiting a couple of years ago. We were
enjoying my CD collection a lot. But when I
put on a vinyl recording of Albenez’s
Iberia, he turned to me and said, “Now
that sounds like a piano.”
Back in the old days we’d grouse over the
lousy engineering and production that went
into so many recordings. I attended the
session in Inglewood of Sheffield Labs
direct-to-disc recording of Jim Keltner on the
drum set. Doug Sax did everything impeccably
and all vinyl lovers know the result. What I
suspect is that the relative proportion of
poorly engineered recordings has gone up with
the advent of digital technology. The new
technology is all so easy to use, and so easy
to misuse. There is clearly nothing inherently
unmusical about the CD format. JVC’s XRCDs
prove it. Mapleshade proves it. BIS proves it.
But in terms of imaging, most of my records
are stunningly better than most of my CDs.
Could engineering and production be the
culprit?
But I haven’t told you anything about some of
my remarkable finds at Goodwill and Salvation
Army. Maybe next time.
