One
can rightly ask: "What should a perfect tonearm do?" It sounds like a
simple question, but actually there are many answers, and
then again more questions and contradictions. The biggest problem is
that the arm must hold the cartridge firmly in place, but at the
same time the cartridge needs to be moved over the record. This
creates a lot of compromises, such as weight, mass,
bearing friction, resonances and much more. Here i look closer at
an arm that a single man has spent a great deal of his
life optimizing. In many areas this arm can be compared to a fine
watch. Precision, perfection and a really nice finish .
The
very elegant Glanz MH-124S is a serious bidding on how it should be
done. The Japanese arm seems almost as an anachronism, as it appears
both simple but also complicated. Today we see 3D printed arms, as well
as arms made in magnesium, carbon fiber, wood and mostly in aluminum.
Many have a variety of adjustment options and are equipped with
micrometer screws for VTA and all the comforts. The Glanz MH-124S is
the opposite. Here we are back to the basics. A 12 "stainless
steel arm (also available in 10" and 9 "), with emphasis on precision
bearings, as well as optimal internal damping of the solid steel
structure. A high-mass arm designed to be used with absolute
low-compliance cartridges.
Glanz MH-124S is number two from the
top in a larger progarm. Glanz only makes arms and shells. There
are three series - the MH 9B and 10B are verrsions using stainless
steel arms, but otherwise chromed brass to the base. The MH-94S,
104S and 124S models are all 100% stainless steel. The type
designation indicates their size in inches. It's the124S (12 ") I'm
looking at here. At the top of the program you'll find 124SD, where a
carbon layer with the same hardness as diamond has been added
to all metal parts. Inside you find pure silver cables with silk
insulation surrounded by polyester fibers. There is a further
attenuation in the counterweight suspension. 124SD is in the price
range of more than 15.000 US$.

STEEL The strength of a metal can be measured in Young's Modulus. For aluminum, the value is 10 million lbs per square inch (psi). For steel it is generally about 30 million psi.In other words it means a steel pipe is three times stronger than an aluminum pipe of the same dimensions. Whteter the same applies to stainless steel, I can not say. The problem is that a steel pipe weighs 3 times as much. Thus, the steel pipe must be thinner and then again lighter. Mechanically there are also other aspects, such as temperature stability and transmission of sound and vibration. It's all very complicated and I leave allt this up to Mr. Hamada. |
A
headshell is also enclosed. Like the rest of the arm it is made of
special high quality steel. The shell is narrow and with a rubber
damping on top. I wondered about the little metal crossbar
used to fasten the cartridge. Here you have a steel arm
with a lot of effort to keep vibrations and resonances down, but
then the cartridge must be fixed with a thin metalbar?
But
np, this is done the right way. The relatively
solid metalbar is of course also solid steel and when the
cartridge is fastened it sits firmly in place. At the same time it
is possible to turn it slightly for optimal off-sett adjustment.
Optically and mechanically, this house and arm make up a whole. Pretty
nice and if you do not use a fixed-shell cartridge, it's a good
solution.
The arm base is 30 mm in diameter and Glanz recommends
a 31 mm hole for easier passage. The mounting plate may be up to 20 mm
thick. Everything came into place without any problems. Antiskating and
armrest can be removed if you do not want them. Glanz recommends
removing these for optimal sound quality. They go to
extremes to keep it as simple as possible and avoid everything
redundant, which may create unwanted resonances. This way of
thinking also shines through, in the construction where no glue or
screws have been used. Everything is press-fit - carefully pressed
together and with the greatest possible precision. This also applies to
the high-precision ball bearings used. As a watchmaker would do,
they are very carefully hammered down into place where they
are stuck firmly.
The "S-shaped" arm itself is internally
damped, so that Glanz avoids what he calls "time echo distortion". In
other words, attenuation of resonances.
The armrest is a bit
tricky. One can not just unlock flip it open. It requires 2
hands where the arm is to be held while the lock is tilted to the
left.
If you have a turntable with a lid, you must take
into account whether the arm can be there. A 12 "arm is reach
uot far back and the counterweight sticks out a bit. My
record player is without lid, so I did not encounter that problem.
A little history
Glanz
is not a new brand. In fact, it dates back to the 1950s. The Japanese
company Mitachi Acoustics products were developed and marketed under
the Glanz brand. They have, for example, made many cartridges, both MM
and MC types. Several of their products were developed by Masataka
Hamada, who in 2008 were licensed by Mitachi to market
his tonearms under the Glanz name. In this way, the Glanz became
reborn, at the time of the growing interest for the
analogue medium. The tonearms are now manufactured by Hamada
Electric in Shizuoka, Japan.
Glanz
MH 124 could immediately seem like a copy of the arms we saw back in
the 70's. The FR 66 is obvious, and today for example.
Ikeda, Jelco, Ortofon, SME, Schick and a few more. All of these
manufactureres makes 12" tonearms. They seem somewhat notalgic in
their appearance with the standard SME fitting .
But there
is more than just a 12 "arm behind the history. Hamadas design
philosophy is based on vibrations and how to treat them. The
cartridge sends vibrations up through the arm, which generates a
lot of unwanted effects. The vibrations must be led away through the
arm, the bearings and down through the base. Everywhere where different
materials meet, there are barriers. Wire suspension, magnetic
disconnection or combination of materials such as wood, metal and
plastic create this transition. Here the energy is sent back
to the cartridge and creates what Hamada calls "echo distortion".
With a construction of steel and the tight coupling all the way there
are no transitions and the energy can flow freely through the arm and
ensure the cartridge the optimal conditions. This is the
explanation why you find no knife or unipivot
bearings here. which will make the arm dangle around only
held in place by gravity. Hamada especially highlights the bottom
oversized pressure bearing which carry the arm. This ensures
a smooth and friciton less motion of the heavy arm.
One might
wonder why the tonearm is made with SME fitting for headshells.
The explanaion is, that Hamada is a big fan of Ortofon SPU. He has
worked for many years with the known Ortofon cartridges and
repaired them for customers in Japan. Therefore, the arm is designed to
provide the Ortofon SPU with optimal conditions. Some other
cartridge manufacturers offer similar cartridges with a fixed
house and the SME fitting. I can briefly mention IKEDA, EMT, Sony
and Dynavector.
Another aspect is attenuation or damping. We often see it in arms with siliconeoil or decoupling down through the arm. Damping is good, but too much attenuation and the sound gets dull and lifeless. The detailsand the air in the music are suppressed. As a solution to this compromise, Glanz uses something they call "parallel damping". The desired effect is achieved without renouncing the dynamics and the fine details. The damping takes place in the tonearm as well as in the decoupling of the counterweight using a triple layer of carbon fibers and ABS plastic as well as special rubber.

I
waited a little with the Glanz Steel House and instead mounted my Ikeda
9Gss pickup in a graphite shell from Italian Audio Silente. This
is heavy! Shell and cartridge weighs 34 grams (In the Glanz steel
house, the combined weight was 25 grams). Both tonearm, sehll and
cartridge thus pulls in the wrong direction of what you
would consider optimally. A quick calculation showed an arm
resonance of 6.3 Hz in this set up (6.8 Hz in the Glanz shell).
However, there were no problems with balancing the arm and tracking.
Bumps and unevenness in the record were played without
problems. Of course, you need to aim for an optimal arm resonance, but
you certainly should not be blind to how well it's been damped. Here it
seems like Glanz has full control of everything.
Adjustment
of needle pressure is done by displacement of the counterweight.
There is a smalll scale on the back of the counterweight, but I used an
electronic needle pressure weight. Glanz refuses to use a spring to
adjust the needle pressure, as they consider this as adding a resonance
source. The same applies to anti-skating, which works as simpel as
possible through a small lever arm.
The lift worked fine, but could need a bit more silicone damping. I do not tthink the arm I borrowed was brand new.
Correctly
the arm should be mounted in a steel base or at least one of aluminum.
However, the loose bases I use for testing the arms are 10 mm thick
acrylic. Absolutely stable, but not quite the optimal solution.
The sound
I
can imagine how some may think that this should sound "cold like
steel" or similar analogues. No, I'd rather say "exactly" like steel.
It "cuts" and reveals everything in both the width and the depth of the
sound image. There is a nice calm controll and everything is placed pin
point in the image. Voices are as nailed stuck in the middle,
if it is where they should be. I know it's a special hifi
phenomenon, but it's so nice to experience.
Initially, one could
think that this it is a bit too clean and analytic, but it is
quickly discovered that it is due to the absence of the soft and
undefined reproduction of the lowest octaves. A clean cut, a clean
sound comfortable free of dyeing and stresses. There is therefore no
artificial loudness or boost at the bottom. On the contrary, everything
seems smooth, precise and very dynamic. The sound is firm and
controlled, and stop when it has to stop. More controlled and
smooth, even compared to my Dynavector DV 507.
The above
with the graphite shell from Audio Silente. I tried the Glanz
headshell. Initially with my Benz LPs. It must be said to be a
successful combination. There was more "bite" and ease over the
reproduction. They were almost in a kind of symbiosis and definitely a
fit. When my Ikeda G9ss came in the steel shell, the
impression was more mixed. Well, there was something more smooth and
easy in the sound, but at the same time the bottom were clearly muted
and less firm. Compared to the heavier Audio Silente graphite shell,
there was less substance and power, as if the music lacked a
stable platform to set off from The dynamics were slightly
suppressed. So here it was clear that the heavy graphite
shell best suited the Ikeda pickup. The following is the graphite
shell on the Glanz MH-124 and Ikeda 9Gss pickup.
