Tonearm Ortofon AS- 309 12" long for SPU-G and SME type Headshells

with the lowest distorsion worldwide and variable mass
The
best and most expensive Cartridge cannot deliver top results if the
tonearm has a poor arm geometry and therefore produces high distortions.
My arm geometry is calculated for the lowest possible distortion with a recognized professional computer program, my tonearm geometry has the lowest distortion worldwide, you will hear it immediately

*******************************************************************

here is one of the last feedbacks from july 30th

Aligned. It is in an aftermarket VTA tower made for the Groovmaster IIti that was on the table before your arm.
I will not going back to the GM!!! Only my $11,000 Glanz MH124 is superior and not by $10,000!
I am thrilled at this arms performance richness of tone is it's major strong point. Bass is tight super extended

and the too end extended and
sweet. No ringing or tonal artifacts with this arm.

Vocals are on par
with the best of the best. Rich defined and harmonically perfect.
Thank you sir. Well done!                                                                   R.W   Miyajima Labs USA importer.

*******************************************************************************

This tonearm does not have a fixed effective mass, but is variable due to its different counter weights and the distance to
the pivot point of the tonearm

It
is one of the very rare tonearms with variable mass worlwide.A tonearm
with variable effective mass, which makes it possible to use all
cartridges with low compliance or with high compliance.

Dear Alfred,
I’m very happy with your tonearm, you can put my YouTube video in your listing.

PHYSICS and GEOMETRY never lies.....

THIS ARMWAND IS OPTIMIZED FOR

LOWEST TRACKING DISTORSION

3 THINGS DETERMINE THE QUALITY AND THE PERFORMANCE OF A PERFECT TONEARM:

1)   EFFEKTIVE LENGHT

 2)  OVERHANG

3)  OFFSET ANGLE

============================

 TONEARM  GEOMETRY:

EFFEKTIVE LENGTH : 321.459 mm

 MOUNTING DISTANCE: 309.4mm

OVERHANG: 12.65 mm

OFFSET ANGLE (DEGREES): 16.89 º

Tonearm geometry with the lowest distortion worldwide, you will hear it immediately

 

the
geometry had to be calculated by hand in the 60s, because you did not
have any computer calculation programs yet, this could never be the
optimum, because the 3 parameters for the geometry are interdependent.
When you change only one parameter  to 0.5mm  the distortions are great. Therefore, tonearms from the 60s can NEVER reach the perfection that is possible with the computer programs today

___________________________________

This tonearm combines the simple aesthetics of Ortofon Tonearms with the current best armtube geometry currently available

 

only
a perfect geometry of the armtube guarantees a low distortion.this is
the first and most important thing with a tonearm.not the material, not
exotic armtube materials or mimics can eliminate a fundamental
distortion that exist due to a wrong and bad geometry.material of the
armtube and Vaccination only has an impact on resonance and vibration
coming from the plinth (engine vibration and music waves) tonal arms are
offered on the market, which cost well over $ 15,000 and are advertised
that give the materials the highest in technology (space travel, NASA
ect)

 the geometry of a perfect tonearm with the lowest  distorsions consists of:

 1) effective length

2) overhang

3) offset angle

 nothing more and nothing less

 these
3 parameters are dependent on each other. This is mathematics and is
based on formulas that have absolutely nothing to do with materials.
With existing PC calculation programs, anyone can see if their tonearm
has the least distortion due to the armtube geometry. This is the only
objective method and not the subjective belief in exotic materials or
great promises.

 

if
the distortions are very high, because the geometry of the armtube  is
bad, then helps  no ball bearings from NASA or whatever. Many
manufacturers want to persuade one. it also no helps no arm tube, made
of 500 years old wood, which is the specially manufactured and polished
by moonlight from a virgin.

****************************************************************

The Armwand  is high damped  with inlet of Balsa Wood

(the
inlet of balsa for damping is precisely balanced- when you overdamped
you will take the life out of the sound and it will get boring)

*********************************************************************

 Armwand with matt surface and inlet of balsa wood

which guarantees no resonances in Armtube and Cartridge

YOU WILL HEAR THIS.
