a wealth of information in the grooves - and the cartridge. The
arm and the turntable dictate the foundation and the resolution
upon which the rest of the playback system is built upon.
continuously amazed at the ability to open up (read, observe,
feel and "see"), the recorded ambience, stage dimensions,
timbre, decay, and the ability to decipher the recorded clues
that the microphones picked up and how they picked it up - all,
by designing and manufacturing those mechanical wonders,
turntables, arm and cartridge, that can do the tricks. Actually,
those aren't 'tricks' at all; they are sound-concepts,
executions, and way of manufacturing...
SpJ La Luce Turntable
turntable is the smallest of the Spotheim SpJ La Luce series.
turntable is a low energy storage, direct-coupled, non-suspended
design. The transparent acrylic platter's mass and inertia is
increased by the embedded stainless steel weights around the
A central, asymmetric acrylic block holds the bearing house.
The pick-up arm is directly connected to this acrylic
central block. An acrylic cylinder is bolted to the
underside of the central block and this forms a T-shaped
La-Luce turntable rests on three contact points and is
levelled by adjustment knobs on each side of the T-shape
support. All major components are individually machined from
billets of transparent acrylic.

SpJ Alba Turntable
newest edition to the SpJ turntable family is the humongous Alba
design has two platters:
(the record platter equipped with the record spindle and the
clamp system) is made of two layers: the top layer is a 42-mm
thick acrylic disk bolted to a soft aluminum disk platter of the
same 330-mm outer diameter. That aluminum disk platter has three
stainless steel spikes that sits on top a seperate carrier,

the belt. The carrier platter's mass is encreased by thirty
stainless steel vertically placed cylinders.

SpJ La Luce CS Centoventi turntable
top of the line, the C.S. Centoventi, is low energy storage,
non-suspended design, driven by a soft belt and a stand-alone
motor set inside a 9kg stainless steel cylinder-house.
La Luce C.S. Centoventi features a 120-mm thick platter with an
outer diameter of 330-mm. The transparent acrylic platter is
machined from one solid block.
mass and inertia is increased by embedded stainless steel
weights around the platter periphery. The ideal mechanical

stylus-induced resonance to pass smoothly into the mass of the

addition to the on-off switch, a separate optional switch allows
the motor to run on a reduced AC voltage.
SpJ Lyla Pick-up Arm
Lyla pick-up arm has been designed in the manner of a precision
instrument, and has been manufactured to extremely fine
tolerances out of materials chosen to insure neutral and
accurate playback of analogue records.
Lyla pick-up arm is made of Titanium; it is a uni-pivot " I "-
shape design that places the stylus tip in a straight line with
both the arm wand longitude and the arm's pivot. The SpJ Lyla
carries a minimal lateral mass.
Lyla Offset-Angle is appropriate for an effective length of
312-mm - according to the classical Bærwald tone arm geometry
calculation, which places the Null Radii at 66 and at120.9-mm
from the turntable's spindle center.
VTA height setting is made possible even as the stylus tracks
the grooves.• Spindle to pivot gauge to set the arm's pivot
distance from the turntable spindle is supplied.
set the stylus effective length is also supplied.
engraved with Bærwald two Null Radii, to check setting of the
cartridge offset angle is supplied with the SpJ Lyla. The
template can also be used to check setting of the cartridge
Lyla pick-up arm may be used with cartridges weighing from 3 to
more than16 grams, due to add on or interchangeable stainless
