A brief word
from the designer
The AXIOM is the result of my more than 35 years of intimate research and !
preoccupation with analog playback - with the specific focus on the interaction of !
the record groove with the cartridge and tonearm.
A truly universal tonearm, which offers all and every option of alignment –
while ensuring the best possible mechanical guidance for any cartridge.
Taking into account the paramount importance of energy transfer in relation to
effective moving mass.
Resulting in a level of performance only obtainable, when each and every aspect of the analog audio tracking
process is attended to with utmost attention to even the most minute detail.
A level of performance, which transcends prior frontiers and opens new levels of musical realism in the
playback of recorded music.
We do share the real passion for music and I am confident that the AXIOM will allow you to hear and enjoy
your favorite records like never before.
Please get yourself accustomed with this manual.
Make sure you familiarize yourself with each and every aspect of the AXIOM’s options.
Your time will be rewarded with outstanding performance - to the benefit of your whole analog set-up and
ultimately your enjoyment of recorded music.
The AXIOM is entirely designed, manufactured and assembled with care and dedication in Bavaria,
Germany.

Techn ic al fe at ures
& general design
The AXIOM is a pivot tonearm featuring a double
nano-gimbal bearing architecture.
The AXIOM is a static, full lateral balanced design.
The AXIOM features an unique compound arm wand -
a combination of surface hardened Titanium and
Carbon Fiber pipes blocked together and internally
damped by an all new design concept, a concept never
before applied in tonearm design and first featured !
in the AXIOM resulting in unmatched fast !
energy transfer and total absence of any parasitic
resonances in the tonearm.
The AXIOM was designed to explore the possibilities
of analog playback to the utmost degree. To
accomplish the best possible analog playback
performance, the AXIOM offers an unique complete
set of alignment features.
Two (2) variants
The AXIOM is available in 2 standard 12“ variants:
*with fixed standard EIA 1/2“ mounting slots
*with SME-compliant detachable headshell mount!
Alignment options!
Leveling the bearing axis!
!
The AXIOM can be precisely leveled by the user,
independent from the turntable or mounting surface.
This is essential to avoid parasitic side-forces prior to
alignment and anti-skating setting.!
SRA/VTA adjusted at the !
cartridge!
!
In the AXIOM the important alignment(s) !
of VTA / SRA can be made at the cartridge – without
altering the static parameters of the tonearm, while
preserving the other set alignments and leaving the arm
wand always horizontal. !
This again is of paramount importance in a static
balanced design to avoid unwanted changes in static
settings (namely tracking force) when changing
tonearm height to accommodate VTA or SRA.!
Offset and Overhang !
adjustment!
!
Offset is adjusted in the prolonged and slightly
widened slots for the cartridge mounting screws.
Overhang can be adjusted at 2 spots, both located at the
head. First of course in the prolonged 1/2” slots for the
cartridge mounting screws. Here the slots allow for up !
to 5 mm adjustment in overhang and thus !
effective length. The 2nd spot is at the collar of the
headshell where it is clamped to the arm wand. This is
an additional spot for further overhang adjustment only
IF NEEDED. !
The whole headshell can be moved back and forth by
up to another 5 mm in this way.!
This should hardly ever be necessary.
!
Azimuth
The headshell’s collar is also the point for !
azimuth adjustment. By loosening the clamp screw the
user may rotate the whole headshell in either direction.
Small indication marks at the rear of the !
headshell’s collar and on top of the arm wand allow for
reference and easy return to former settings.!
Dynamic anti-skating!
!
Skating compensation – or anti-skating – !
adjustment in the AXIOM is dynamic and !
follows the tangential geometry of the !
AXIOM. If carefully operated, it can be !
adjusted during play. However we recommend that !
you do ALL adjustment or alignment at the AXIOM
ONLY with the cartridge / stylus lifted off the record.

Tonearm height – VTA!
!
Tonearm height can be adjusted on the main VTA-
tower of the AXIOM.
One full turn of the large top knob adjusts height by
precisely 1 mm.!
Tangential alignment!
!
It is possible to align the AXIOM to the !
standard tangential curves of Baerwald, !
Stevenson or Loefgren in any version and !
standard.
The absolute best possible performance !
however is obtained only by aligning the !
AXIOM to the new UNI-DIN tangential curve.
It’s geometric design is uniquely based on !
the UNI-DIN, a tangential curve formulated !
in 2011.!
Step-by-step !
procedures!
!
In the next pages I would like to take you through the
mounting and alignment options of the AXIOM.
All procedures are illustrated step-by-step.
The pictures will give you most all of the !
information you need to perfectly mount and !
set-up the AXIOM.
However, I will guide you through this with !
my comments too and try to give further !
information whenever the mere picture may !
not tell the whole story.
We all like to get a new tool working as fast as
possible.
May I please encourage you to follow me through this
mounting and set-up procedure as precisely as possible
and to the very end - it will be to your advantage.
This will ensure that you get the best !
possible performance from your AXIOM !
and take advantage of all its features and !
capabilities.
!
Single-point mounting vs. !
SME slide base!
In this manual we will cover the AXIOM mounting
with the standard 1-point mounting.
In addition there is the option to mount the !
AXIOM easily onto any existing 9” or 10” SME
armboard.!
!
We do offer - as a special order item - a !
dedicated SME-slide base for the AXIOM.!
If interested, please ask your dealer for the SME-slide
base for the AXIOM.
There is no difference in performance between the 2
mounting options.
We further offer other adaptor mounting plates for
existing armboards upon your request.
If you are in need of a mounting plate for other
existing armboards - to take advantage of !
existing pre-drilled armboards - please kindly check
back with your dealer who will contact us.
GENERAL NOTE
Please make sure prior to setting up !
the AXIOM that your turntable’s !
platter and armboard are dead level.

Please remove(1) of the lateral weight assemblies and
the main counterweight with the small secondary
counterweight from the accessory box.
Also please take the (3) different height 29 mm
diameter stainless steel mounting washers.
Please do open the tool box to have easy access to the

Place the washer with the „rim“ side down over the
thread hole.
You can also use the special thumb knurl head screw -
if you don’t need to cover the mounting hole later with
the (purely cosmetic) cover plate.
Please take one (1) of the 3 different height D29 mm
stainless steel mounting washers and a M5 screw which
is according to the washer.
For the smallest height washer take the shortest screw,
for the middle height the middle … etc.
Mounting the AXIOM
Place the screw through the mounting hole in the
AXIOM’s mounting board.
Gently place the AXIOM - holding it at the VTA tower
like in the picture - over the plain top of the washer
holding the screw in the other hand.

Now please note the 3 grub screws in a circle - !
each at 120° - around the mounting screw in the center.
We will return to the mounting screw later.
Gently screw the M5 screw down - not tighten it, but
just holding the AXIOM in place and still allowing for
some little „play“.
Please turn back the M3 grub screw in the end of the
counter bar by 1-2 revolutions.
From the AXIOM’s accessory box please take the long
tool box and open it.
Select the „1.5“ Allen bit and put it in the tip of the bit
holder
