The
new "Glider on steroids"?
MC
cartridges are considered, by most of the analogue-oriented
audiophiles, to be the entrance door to the
true analogue high-end. It's not that great
(and costly) moving magnets or moving iron cartridges
don't exist (Grado, Decca/London and Clearaudio
are the first ones that come to my mind) but
the heights of reproduction are scaled by MC
cartridges more easily. Some reasons of this
can be traced in the facts that the working
principles of MC cartridges allow for a greater
linearity, and that MC cartridges have a stylus/cantilever
assembly which is directly connected to the
generator: it's not by chance that the best
Grados don't have a user replaceable stylus
and that some wild experimenters report of a
much better sound from MM cartridges if home-made
and non-reversible couplings, like Super-Glue,
are used between the cantilever and the cartridge
body - it goes without saying that neither the
author nor Videohifi.com are to be held responsible
if you decide to follow those wild experimenters
and destroy your cartridge, your finger or both.
Furthermore, the way in which MC cartridges
are (forcedly) built allow for lower, better
channel tolerances and separation; again, their
resonance frequency is higher and they are far
less sensitive to the capacitance of the phono
input and to that of the phono interconnects.
Their main disadvantage is their low output
signal; the most "precious" ones have
a lower than 0.5 mV output, while MM cartridges
output is normally higher than 2.0 mV. This
peculiarity forces the usage of high gain phono
sections, or of dedicated step up units, such
as linear signal preamplifiers or transformers.
This obviously causes other problems: noise
and EMI/RFI. Placement of components, cable
routing, proximity to radio stations, all of
these facts become critical for the final result.
Another
thing to keep in mind when an MC cartridge is
used is that its sound can vary, very significantly
in some cases, according to the phono stage
input impedance: the ideal load resistance for
a cartridge can vary from just a few ohms to
47 kohms - MM cartridges, conversely, are standardised
for a 47 kohm load, excluding those peculiar
Decca cartridges which are one of our Editor's
pet loves.
The cartridge here under scrutiny is a relative
novelty; Thomas Scheu, who begun his adventure
in our field building DIY turntable parts, going
on with complete turntables and tonearms, has
evolved his business in a web shop dedicated
to all things analogue. For a while he's been
selling a Benz derived cartridge, named Scheu/Benz
MC, in different configurations, with elliptical
or Fritz Geyger S stylus, and with your choice
of 0.3 or 1.6 mV output (by the way, I didn't
mention high output MC cartridges above; I think
it's enough to know that they are a variant
of moving coil cartridges which, by using an
higher number of wire turns in their coils,
allow for deliver a higher output, an advantage
which is offset by the fact that the higher
weight of the suspended mass, in general, causes
less immediacy and lower dynamics if compared
to a lower output version of the same cartridge).
The cartridge was known as the "Glider
on steroids", as it was based on the known
Benz Glider, which was modified with some parts
of the Benz Reference. Not the least of its
advantages over the Benz model was the fact
that, thanks to Thomas Scheu's direct sales
model, the cartridge's price was, in some markets,
lower than that of the lesser Benz model on
which it was based. Recently, and coinciding
with the presentation of the Series 2 Benz cartridges,
the range was revamped; the high output version
is now sold only with the Geyger S stylus, 1.2
mV output and copper coils for 649 Euro + S&H;
the low output one (the one I am telling you
about) sports the same stylus shape, silver
coils and a 0.3 mV output, and is sold for 779
Euro + S&H. A version of the Ruby is also
available, an Open Air one (so the variant without
the Bruyere wood body), for 1200 Euro + S&H.
Expected stylus lifetime is about 1000 hours
(as for all Benz models and retippings); retipping
cost is 300 Euro for the model reviewed here.
Presentation
and set up
The
cartridges arrives in the usual brown box of
non top-of-the-range Benz cartridges, which
includes a small (and somewhat imprecise) round
shaped bubble level, a small screwdriver and
mounting screws in different lengths - no nuts,
as the cartridge sports tapped holes. There
is an individual calibration sheet also, with
a nicely flat looking frequency response trace.
The "manufacturer declared" specs
are reported inside the top of the box; here,
the model's name is indicated as "Benz
Micro Reference Silver". It's probable
that the cartridge is a naked, wooden body-less
Reference Silver, also in view of its price.
This
nakedness doesn't make the perspective to mount
it on a tonearm an inviting one: there is no
stylus guard, as there is no place where a stylus
guard could be mounted; everything is exposed,
even the wee wires (which seem really to be
silver) connecting the generator to the output.
So easy, calm and firm hands. At least, what's
left of a cartridge body seems to be able to
resist close encounters with a hammer.
However,
the nakedness helps a lot during the alignment
phase: the fact that the cantilever is so exposed
makes it really easy to put the cartridge just
where your favourite protractor dictates. .
Optimisation
and sound
By
optimisation I mean all of those operations
which an analogue lover usually performs after
the basic set up procedure (i.e, after assuring
the cartridge to the tonearm, aligning it and
setting the weight in the middle of the manufacturer
recommended range): fine tuning the tracking
weight, setting up antiskating, VTA, azimuth,
phono preamp gain and resistive load. I found
out that the best sound was obtained, on the
two arms I tried, with a smidge less than two
grams for tracking weight, just enough antiskating
(none of the two arms has a precise antiskating
scale; one of the two, the VPI - about which
I will probably have something more to say in
some other writing of mine - has even a peculiar
and controversial antiskating arrangement),
slightly tail dragging VTA (the arm lower at
the balance weight end), 400-600 ohm load. In
comparison with the older Scheu Benz Geyger
Low, a cartridge I used up to the end of its
stylus life, the VTA seemed to be less critical
and the output seems to be lower, but let's
not anticipate too much.
To define the sound of the current version,
I must start by describing the sound of the
older, copper coil, one. That one was a very
captivating cartridge, with a good dynamic range,
an unbound, well flowing sound, a slight bump
in the frequency response in the higher range
of the low frequencies which gave to the sound
a character very adept adapt to reproducing
jazz and rock music, also in view of the facts
that all of that was accompanied by an inviting
midrange and, loaded in my favourite range,
by a slightly descending high frequency response.
The older version wasn't the last word in detail
resolution and in focus, though: the soundstage
wasn't lacking, as both width and depth were
satisfying, but often, mostly in comparison
with higher class cartridges, the entities were
represented more as clouds than as point sources,
just as if the slight detail obscuration wasn't
enabling the cartridge to discriminate the source
from its very first reflections. Another slight
problem, one which I thought I perceived only
with a small number of records, was a slight
discontinuity between the frequency ranges,
maybe correlated with that above mentioned frequency
response anomaly. I think the new version solves
most of these problems, while, at the same time,
it changes slightly the sound's general character.
The slight frequency response bump is all but
gone, leaving way to an enticing frequency response
linearity; the slight colorations I perceived
with the older model are much lower with this
new version. The slight frequency response discontinuity
is history, confirming my hypothesis that it
was correlated with the frequency response anomaly.
What
has changed in a really significant way, though,
is the general transparency; the level of the
detail reproduction, while still not being record-breaking
as that of reference cartridges like my Lyra
Clavis Evolve, is very satisfying and constant
throughout the frequency range; this allows
a focalisation which, while it might not satisfy
those who are looking for fireworks, might well
be more realistic than that of some top digital
sources or, again, of some cartridges which
cost some times the price of this one. Focalisation
leads us to soundstage; stage depth, which was
very good with the older model, seems to be
intact; width is much improved, as is height
- a parameter which never ceases to perplex
me, so much that I am not inclined to attribute
it a significant importance while evaluating
other products than speakers or the ideal affinity
between a speaker and a room.
I
was talking about VTA, above: the old version
was quite critical, very sensitive to microvariations,
quite difficult to set up. The new one is much
more tolerant, I think, and I don't know why,
as the stylus shape is the same; still, it's
easier to get to the point where you feel the
set up is optimal. Another surprise, the new
one is a better tracker: the older version wasn't
able to track the second-to-last track of the
(old) HiFi News and Record Review test record
without some slight distortion; the new one
passes the test with flying colours. This better
tracking ability is evident during normal (not
steady-tones J) listening sessions; I perceive
a new calm in tracking the grooves, an ease
not matched by any other MC cartridge I have
experienced, extended also to the worst records
and to the innermost grooves. This tracking
calm reflects into a new listening calm, as
if that almost subconscious worry about my beloved
records wearing out was even lower, almost absent.
I think one of the undeclared improvements is
the cantilever suspension…
So,
in summary, the cartridge is more neutral, more
detailed, less coloured and easier to set up
than its previous incarnation. Disadvantages?
Well, here I must confess one thing, evidence
of which you can find in the Italian version
of this review, if you know my first language.
I was ready to write, here also, that the old
version was somewhat more enthusiastic than
the new one, that this was because I perceived
it as a top-of-the-cheap-range (cheap is a relative
word, it's clear that, if you can afford to
spend 600 Euro or more for a phono cartridge,
you have solved most of your economical problems),
while the new one is a kind of "your first
super cartridge". This argument stands,
I still perceive this cartridge as the cheapest
super cartridge, but that sense of it being
less enthusiastic than the older one is gone,
since I tried to trust my feeling that the newer
one was lower in output. So I set the phono
preamp gain a smidge higher, and the enthusiasm
was back. I think a follow up will be due for
our Italian readers…What remains, against
the older version, is a neutrality which can
sometimes be misinterpreted as whiteness, but
which is absolutely not. Is this neutrality
and low coloration level correlated with the
use of silver wire? I won't tell you that, I
am not the kind of guy who generalises…
The Silver Low is, to summarise, a more versatile
cartridge than the older one, a cartridge of
which you won't think it's more adept to reproducing
a particular musical fare or diet, while keeping
in line with the Benz tradition of delicacy
in detail reproduction and of gentleness.
An interesting comparison can be that with the
Ortofon SPU Royal N, which costs a little bit
more according to the official list, but which
can be obtained sometimes at a comparable price.
The SPU, that old dinosaur, is heavier, tracks
less easily and does it at a 3 grams weight,
is much more difficult to optimise and much
more critical in partnering components choice.
Soundwise, the comparison is perfectly possible,
and I think I can understand a preference for
either one. The Scheu is more neutral, more
extended, more detailed and warmer sounding;
the SPU, from the lower midrange to the lower
high frequencies, seems to respect instrumental
colour more than the Scheu - I don't think I
have heard the wood of which string instruments
are made better than with the SPU , and has
that touch of indefinable, inexplicable "magic"
which has won so many fans to it. Surface noise
is low with both cartridges, and somewhat lower
with the SPU. The SPU, though, has a tendency
to become unbearably bright if coupled with
the wrong partners, and I don't think it is
a first (or even a second, thinking about that)
choice for a listener who prefers modern, lighter
music: the low frequency attenuation robs some
of the physical impact which is integral part
of the experience. As a final consideration,
I think it's the Scheu which is to be preferred
by someone who loves all music, and doesn't
want to waste most of her/his time looking for
the ideal partners.
No
more Glider?
I
think it's clear, from what I wrote, that I
don't think this is a Glider anymore; this cartridge
is the real top transducers' entry level; and
this is also an intelligent choice, as the -
unavoidable, I think - price increase is fully
justified in this way. An intelligent product,
rationally conceived, somewhat easier to admire
than to love, at first, but which is able to
prove itself dependable in perspective: a long
term partner, respectful with records, neutral,
with that kind of sweetness Benz cartridges
are characterised by. The price is, again -
as usual, for Herr Scheu - almost bargain-level,
as it is comparable to that of the Glider in
most markets…
