The ADC
LMF Carbon Fibre Low Mass Tonearms
The LMF-1
has an integrated head for lowest mass.
The LMF-2
has a removable head.
We chose
carbon fibre because of its low mass to high tensile strength ratio. Then we
were able to further lower the mass by abandoning the traditional tubular shape
and engineering the fully tapered profile. Carbon fibre has yet another asset
which anyone with a serious love of quality music reproduction will love. The
inherent properties of the material are antiresonant.
The
combination of a fine cartridge and the LMF low mass tonearm will not interact
with typical building resonant frequencies or with typical record warp
frequencies. The LMF tonearms are styled in mat-black to blend into the design
of any high quality turntable.
The cueing
is viscous damped in both directions for optimum stylus care. Tracking forces
are calibrated in 1/10 th gram increments with a precision click-stop dial.
Anti-skate adjustments are infinitely variable to 2 grams.
The LMF
tonearms each come with three cylindrical counterweights to enable you to
achieve zero balance with minimum effective tonearms mass, regardless of the
weight of your favorite cartridge even up to 11 grams.
The LMF-2
has a removable head.
This allows
the audiophile whose tastes require alternative phono cartridges to make
premounted changes in seconds, both permit the use of the highest compliance
cartridges with lowest tracking forces.
The pivot
system uses stainless steel instrument bearings, which are hand picked and
perfectly matched to both the outer and inner races for virtually frictionless
movement without the vulnerability to damage found with typical
"knife-edge" bearing sytems.
