Scheu
...
Probably
doesn't ring a bell. Allow me to explain, then.
Thomas
Scheu is a German engineer and machining shop
owner with a charitable nature (or so I imagine
him). Some years ago he started making turntable
parts, then kits (serious kits), selling them
at prices that seemed too low for the quality
on offer. While visiting fellow Analogue Addict
Hartmut Quaschik in Munchen I got acquainted
with such a DIY turntable. It seriously triggered
my interest.
Now,
a couple of years later, things have grown a
bit. Now including exposure to the rest of the
world. To wit, Scheu's delicious turntable kits
are, in a lighter version, marketed in the USA
as Eurokit (how do you like that name?), while
some design and manufacturing input is given
to the range of seriously high-end Amazon battery-powered
record players. And of course, the original,
affordable Scheu turntables can still be had
in Germany and thereabouts.
But
a turntable alone does not make music. So there
came two unipivot tonearms, a 9" and a
12".
And
a cartridge. Not a Scheu design, but decidedly
Scheu-inspired (that charity thing again). Handmade
by Albert Lukashek of Benz Micro, the MC Scheu
is a cross between the latest Glider and Ruby
models. Available with Gyger S 5x120 um fineline
stylus, and in standard output (1.6mV at 3.5cm/s)
or low-output (0.3mV).
Lows
and highs of moving coils
I used to sneer at high-output moving coils.
After all, many of that breed aren't/weren't
exactly to write home about. Then again, it
is a breed mostly confined to the budget class.
Small wonder then. My interests in something
with output voltages in excess of 500 microvolts
were suddenly sharpened when I found myself
designing a JFET feedbackless phonostage for
MMs, but entirely without a suitable cartridge.
Maybe the benefits of that preamp's simplicity
could be offset against the necessarily heavier
coils and higher impedance of a high-output
MC. A reasonable compromise seemed possible,
and suddenly a formerly-despised breed of cartridges
attained rather attractive qualities!
After
some negotiations I had the 1.6mV Scheu where
I wanted it. Or almost. It was still my job
to move it from its box to the business end
of my tonearm.
Not
an easy job, this, and certainly not one for
the faint-hearted. To avoid housing resonances
intruding on the performance, the MC Scheu is
a totally naked, skeletal design. Such X-rated
cartridges seem to be de rigueur these days
(Lyra, Van den Hul, ...), but interestingly,
the - also wonderful - Jan Allaerts moving coils
tackle the same vibration-transmission problem
with a very large, very light housing only loosely
attached to the cartridge's main structure,
thus avoiding the ingress of dust and dirt.
Seemingly a better solution.
Be
prepared to spend half a day on meditation before
attempting to build in this MC. As for me, I
was all to happy to own an SME IV tonearm, its
hands-off approach to cartridge alignment taking
away part of the risks. And luckily the long,
dark, and totally exposed cantilever sure is
a good aid in getting things as they should
be! VTA was set with the arm's tail slightly
down. The cartridge's mass is a low 6.6g, meaning
that the SME's counterweight ran very close
to the bearing.
Figures
for techies
The MC Scheu comes in a small box, together
with a round spirit level, non-magnetic screwdriver,
and an individual measurement sheet. Frequency
response is almost ruler flat from 30Hz to 20kHz,
with a downward tilt: the bass sits 1.5dB or
2dB above the highest treble. The high-frequency
resonance peak so typical of many MCs is almost
entirely absent here. Also very impressive is
a huge channel separation exceeding 35dB in
the midband, and still reaching 25dB at 15kHz.
Benz claim an excellent channel balance better
than 0.5dB: with many competitors the norm is
1dB or even worse!
Despite
a 40 Ohms source impedance there was no trace
of hum in my setup, and I even could leave the
tonearm's ground wires unattached. The cartridge
directly fed the gate of the first FET in my
phonostage, this a 2SK170 working entirely without
feedback. Passive RIAA and a second stage of
a cascoded 2SK170 completed this preamp, for
a total gain of 44dB or so. Load was 1k, which
is a minimum for this cartridge. The alternative
phonostage used was an opamp-based Trichord
Dino, set at 48dB and 1 or 47 kOhms, and sometimes
fed from a large Trichord HR power supply.
Tracking
at 1.9g (measured on the Shure gauge) didn't
sound totally secure and the first distress
on the Hifi News test record could already be
heard on track 2, whereas my Ortofon plays even
track 3 without buzzes! On actual music, and
re-set to 2.0g, the Scheu tracked well and even
seemed to do better now than the MC-25FL. (I
didn't re-check with the test record.) Its handling
of noise and surface blemishes also was excellent,
a god-send given the second-hand origins of
50% of my LP collection.
Listening
I find that budget moving coils, such as my
own Ortofon MC-25FL, while very good for the
money, increasingly sound like approximations
when climbing the scales. Listen to a triangle,
for instance, or cymbals ... But after only
fifteen hours in the groove the Benz MC Scheu
delivered a resolution in the midrange and treble,
a wealth of refined detail, and a sweetness
that put it into another league altogether.
As
a result of this insight and musicality, the
Scheu helped making sense of complex music like
Joe Jackson's. It did so by clearly unraveling
the separate strands and lines played by individual
instruments, even at crowded passages, while,
luckily, keeping an eye on their interplay.
With
all phonostages used the Scheu succeeded in
painting a remarkably wide soundstage, with
good and stable lateral positioning. Depth too
was rather fine, certainly a cut above my own
Ortofon's performance, but ultimately not in
the same holographic league as e.g. the Dynavector
DV-1 at Geoff's (I know, I know: differing systems
and rooms, etc, but what that Dyna does still
is to die for!) Synthetic sound effects (Trevor
Horn-produced eighties records!) were often
projected forward with a force, stability and
specificity that made me wonder where the 5.1
surround system was hidden.
Tonally,
I had expected a certain lushness, given the
directions from where I got the Scheu recommended
from. Well, in the end this turned out not to
be so: the MC Scheu certainly is not a vintage
Koetsu on-the-cheap (then again, even today's
Koetsus aren't overly lush anymore). No, the
Scheu was neutral, with controlled treble that
never went bright. Slim and clean with the Dino
and Era phonostages, a bit warm with the more
tube-like FET preamp, and always sweet and utterly
without tracing nasties.
Bass,
while not overpowering, was nimble, tuneful,
and very well contoured. In fact, the bass of
the Michell/SME/Scheu combination was now well
ahead of my usual Rega/Hawk CD source, with
good detail, a decent portrayal of atmosphere
in the lower registers, and a lot of slam. Bass
also went deep, but again, it wasn't very weighty.
Resolution
and overall openness were very good. Musical
strands were kept separate and audible throughout,
meaning that temporal and spacial (lateral and
fore-aft) separation are well indeed. This may
seem contradictory with a slightly soft-focus
sound, i.e. the sound sources themselves were
not overly etched. Voices were not forcefully
portrayed, but otherwise were very detailed
and characteristic of the individuals behind
them. Midrange quality was fine, very much 'singing'.
Dynamics were fine too, although the Scheu can
be classified as a mite polite and laidback.
Wrapping
up
Of course it is regrettable that I did not have
a 'real' Benz Glider to compare with, or for
the matter Benz's new economy-Glider, the ACE.
Nevertheless let it be clear that the Scheu
is a very competent cartridge that bridges the
gap between 'budget' moving coils and true esoterica
by offering a large part of the finesse, control
and composure, and the utter lack of nasties,
of the latter, even if the sonic fireworks are
somewhat subdued in the process (but not by
much). Tonality is even-handed and neutral,
and the handling of less-than-pristine vinyl
is excellent. Yes, the big cartridges do still
sound better, and by a considerable amount still,
but do you really want to invest $2000-3000
into a thing with a limited life?
In
most export markets a Glider costs more than
a Scheu. And the latter, at least when directly
bought from Germany, does not cost that much
more than the list price of typical middle ground
MCs such as the MC-25FL, DL-304, Blue Point
Special, or Dynavector DV-20. A bargain seems
to emerge ...
And
so we come to the end of the story. Or wait
... The real end of the story is that I'm keeping
the review sample. Capice?
So,
Herr Scheu, das war's. Kan ich jetzt einen Plattenspieler
probieren, ja?
