I
must admit that, when about one year ago the rumor spread
of this very peculiar turntable mat, I thought it was one
of the many mountebank exercises of a market that, relying
on an apparently unlimited trust by its public, has been
producing quite a lot of swindles along the last twenty
years. Moreover, the description of the item - confirmed
by the name chosen by the manufacturer, "The Donut "- recalled
to my crowded and maybe now fragile mind of hyper-imaginative
audiophile, not really charming and pleasing sights. For
instance, it recalled inflatable ring cushions used to allow
persons suffering by proctologic diseases to sit down painlessly.
Or, the half-deflated tire inner tubes which fat swimmers
clung to in the (then, now a kind of miracle has been made)
ferrous and hygienically scarcely attractive waters of the
sea shore near Rome. Or, more, those arm supports that an
orthopedist with a criminal attitude imposed to me in my
tender childhood to recover, in his opinion, a broken collar-bone
and which on the contrary would bring me these endless spine
problems I daily deal with. In a word, no attractive image
was recalled. As it's well known, if hi-fi stuff, especially
high-end stuff, doesn't charm, it doesn't exist. But word
spread a lot in Italy too. Photos kept on not convincing
me, who knows why, maybe because one tends to keep the first
images he recalled and to overlap them to the current ones.
So I had shifted from a stage "it's a swindle, and it's
ugly too" to a next stage "It may work, but it has to stay
clear of my turntables".

But the story was going on, somebody that had it delivered
from the U.S. affirmed that it could make even a Technics
1210 sound good (I'm joking, provoking the members of the
very active "Esoteric DJ Fan Club"). At last some passionate-tester
"pen pals" and story-teller of sounding gadgets, decided
to pack a small company to market this and other accessories
and complements, and I found one in my hands. That's ok,
you could have said from the beginning (and they're likely
to have said it) that it's named "Donut" just because it
bears a hole in its center, meaning it's scientifically
deprived of the part correspondent to the label of an LP.
Oh yes, because a "Donut" - you don't need to have been
to the U.S., you just have to have been to a McDonald's
- is exactly that blown up, ring-shaped cake we have ignored
to be a Donut for most of our lives. We have always called
it, what a chance, cake, ordering it at our Café at breakfast
together with a cappuccino (that blend of leaven, lactose
and caffeine that is deadly for your health but whose pleasure
you can't do without). Apart from jokes and prologues, the
item is actually a stylish and well-crafted piece. I will
go further and take a position: it turns out to be elegant
on most turntables, thanks to its cross-fibers pattern.
Moreover, after having laid it with a slight initial sense
of horror upon my Thorens TD 124 with Rogers jewel-case
base and Pritchard wood tone arm, all rigorously original
and belonging to the same historical period, I left it even
there for quite a number of days. i.
For the not initiate: the importance of a mat
The
mat will be considered by most of you a definitely secondary
element in a turntable. An element that sits there just
because that's the way it goes; but it plays on the contrary
an important role both under a sonic point of view and in
the struggle to cut noise down. Let's start from a fundamental
statement: a turntable system (with its tone arm and its
cartridge) is actually a complex system to suspend a microphone.
This microphone has to catch very weak signals laid on a
spinning object and send them to an amplifier; this latter
on his turn will take care of magnifying them and of sending
them to the speakers that will turn them into air movement,
that means, in sound. Signals are weak and the microphone
is mighty, so it tends to pick up and to send to the amplifier
both the signals which require its action, and those (noises,
vibrations, static sparks, electronic pulses) that nobody
has ever asked it to pick up. But, you know microphones
are in the best case precise and thorough, but in no way
are they intelligent and capable of making distinctions.
The amount of noise generated or picked up and fed back
by a turntable system is - with all evidence - inversely
proportional to the quality of its construction and of the
efforts to insulate it from the surrounding ambient and
from the same components it's made with. In this complicated
system of war to the noise, the mat, I was saying, carries
out a fundamental task. In fact, it has to insulate the
vinyl disc from the turntable platter; platter that spins
upon a shaft coupled to the engine then to different transmission
mechanisms depending on the drive layout chosen. You can
easily figure out how much noise can be generated in this
part of the turntable, but that's not all, because the LP
itself is made of a resonant matter (little, but it is).
Therefore, one of the style exercises more practiced in
this field is that of trying to dampen as much as possible
those vibrations generated by the disc itself or brought
to it, though in a minimal part, by the tracking system
itself with its motion and weight. The use of high-quality
thick vinyl, where applied, is always praiseworthy anyway.
The non-perfect planarity of the disc, therefore the existence
of hollow, resonant spaces between it and the platter, might
be - and often is - another important source of noise. Most
of the turntables in the market are equipped with rubber
mats, of different thickness and density, more or less effective.
Some English turntables - traditionally Linn leads the rank
- mount felt-made mats, regarding these as far better ones
in terms of insulation and noise abatement. Some other turntables
- the Pink Triangle first - bear no mat, trying to cut the
story short through anti-resonant acrylic platters, instead
of metal-made ones. The market offers also mats manufactured
according to different solutions, all intended to replace
the factory ones.
The
Donut, this by now famous stranger
After
this short recall for the not initiate that will have been
directly skipped by the initiate, let's talk about the Donut.
I was saying that the mat is made of a pattern of crossed
rubber, conductive fibers: It looks rather thin and very
flexible. Its soft and elastic construction grants an always
practically perfect adhesion to the disc surface (still,
neither the Donut can cure deformed records). The fact that
the fibers it's made of are slightly conductive is fundamental
in operating turntables with an acrylic platter. In fact
the disc's path to ground is normally granted by the contact
between the disc itself and the metallic platter connected
to the spindle, allowing static charges to be grounded through
the turntable ground connection, indirectly connected to
the same platter and spindle. Being acrylic platters not
conductive, according to the opinion of the Donut designers
this important chain is broken. Anyway, let's not get trapped
in the endless technical explanations, more or less understandable,
more or less demonstrable, offered by the user's manual.
A manual, I have to say, that is well done, and that is
also honest in technical explanations, avoiding the technobabble
so many U.S. "esoteric" manufacturers have got us accustomed
to. Let's focus on the target instead: does the Donut work?
How does it work? Is it worth its price? Well, I have to
admit that my skeptical attitude had no foundation. Maybe
it came from having seen some too enthusiastic description,
one of these that bring more damages than advantages to
a product, like "it changed my life" or: "now my Pioneer
sounds better than my neighbor's Goldmund, and in bed my
wife is better than Swedish hard-core movies". I just say
that the Donut works, generally speaking, extremely well,
getting its job of noise insulation and vibration cutting
completely done. A job other mats get done too, but not
so well. bene.

Life
through Donut
It's
clear that where you have abatement, down to extremely weak
but anyway insidious thresholds, in the noise, as a counterweight
you will get more dynamics. The equation is easy: the power
from your amplifier stays the same, if it is used, in a
larger or narrower measure, to amplify noise instead of
music signals, the dynamic spread tends to close. You will
also get better micro-dynamics (the higher the noise threshold,
the harder it will be to reproduce and/or hear the weaker
music signals), better airiness and spatial likeliness (since
noise does not follow exact rules, but is shaped in space
with hard to forecast patterns). To cut a long story short,
it does the job that a good quality mat is supposed to.
But it does it better than any other mat I've ever come
across. I made a comparison with the Yves Cochet mat, which
I've always considered the best among those I own, and the
Donut came out of the match definitely proudly. It's very
easy to use since it has a good adhesion to the underlying
surface, even when it's smooth and polished like it happens
with acrylic platters. Even if it's just laid upon the platter
it doesn't slip when changing the disc or the side of it
(unless one does not perform especially sudden and quick
movements, I mean, I wouldn't suggest the Donut to DJs),
It is thin enough not to create major VTA (stylus' vertical
tracking angle) problems with those arms whose height can't
be adjusted, and to require little adjustment to those who
include this setting. Gets little dirt and it's easy to
clean. Fundamental issue, it costs little, 45 EUR in Italy
(delivery included, it's sold by mail), against the 45 USD
it costs in the U.S. Like all the accessories aimed at fine-tuning,
but in an even more evident way than usual, the Donut delivers
different levels of performances (appreciable anyway) depending
on the layout and on the intrinsic quality of the turntable.
It almost made me cry at miracle when placed upon an old,
but still strong, price/quality ratio champion like the
Sansui SR 222 MKII. It has showed impressing results with
a Fidelity Research Professional (by the way, those who
are looking for a pro, direct-drive turntable capable of
real audiophile performances at a very reasonable cost,
try to find on the second-hand market this record player,
instead of that "famous DJ turntable" that, I'm sorry to
insist, has very little of audiophile gear). The Donut has
demonstrated its, I'd say, significant contribution to the
top performance of a superb-breed turntable like the Thorens
TD 124, while with another and more modern record player
I regard as excellent, the Yamaha PX 3, the outcome, though
rather significant, has been less outstanding. Placed upon
the acrylic platter of an Empire/Benz 998LE, it just seemed
to be born to be there, and the same with the Clearaudio
Solution. With many record players it works at its best
if directly laid, as logic would require, upon the bare
platter, while with other turns out excellent in plot with
the original mat (with the Thorens 124 for instance, whose
original mat is hard to replace). I couldn't try it (guess
why?) with the Transcriptor. To summon up, anyway, a mat
that is unlikely to make you regret the bucks you spent
for it, regardless of the extent of the improvements you
will achieve. This is one of these rare items that a reviewer
can be recommend even blindfolded and with no major problems
with his conscience. Perhaps you'll say I'm deaf, but I
surely won't have sent you bankrupted
