Lyra Titan
Compared to the D.C.t, the Titan is conceptually more sophisticated,
offers a higher level of component design and quality, and delivers
a superior level of sonic performance in every possible way. The
Titan's potential for detail retrieval, dynamics, perceived frequency
extension and tracking have been all been much improved. In addition
to having the potential for a much higher level of performance,
the Titan has also been designed for greater ease of setup. In
other words, the Titan makes it easier for more audiophiles to
extract a greater amount of its performance potential.
As a design, the Titan takes the best aspects of the Parnassus
D.C.t and Helikon, and introduces further advancements of its own.
As with all other current Lyra cartridges, the only components
that create the magnetic field of the Titan are two symmetrical
disc magnets. The magnetic field is therefore also symmetrical,
and the field distortions created by conventional polepeces and
offset magnets have been completely eliminated. The magnets are
made of a new neodymium compound that is the most powerful magnetic
material in the world. The improvements to the magnetic field result
in more accurate conversion of mechanical vibrations into electrical
signals; in other words, lower distortion. At the same time, this
allows the coils and cantilever to move more freely, leading to
improved low level resolution and better tracking abilities, particularly
at low vertical tracking forces.
The Titan's body is machined from a single piece of titanium alloy,
which has been curved and shaped in a manner calculated to minimize
standing waves and internal reflections and resonance. This attention
to detail has also been extended to the interior body structures,
which are too intricate to be formed by mechanical means. A different
process called electrical discharge machining was therefore employed,
not only because of its ability to fashion complex shapes, but
also because unlike conventional machining, it is a non-contact
process, and therefore does not create any mechanical stresses
in the machined structures. The superior rigidity afforded by the
Titan's solid, intricate, low-resonance body construction helps
create a clearly defined reference pivot for the cantilever, which
improves the conversion accuracy of mechanical vibrations into
electrical signals. The rigid titanium body also creates an efficient
path for the vibrations from the stylus to be channeled away from
the critical signal generator area and into the tonearm, where
this energy can be dissipated effectively. The titanium alloy itself
is a different type from that used in the Parnassus DCt, and has
been chosen specifically for its low-level of self-resonance and
advantageous sonic properties.
Although the Parnassus DCt was a semi-open design, the Titan is
fully nude, with a body shape that has been designed to minimize
cavity resonance, and also minimize the presence of conductive
materials in the vicinity of the magnetic gap and signal generator
coils. For similar reasons, the front magnet carrier of the Titan
is both non-magnetic and non-conductive. This non-conductive, nude
construction prevents the formation of dynamically induced variable
eddy currents that would otherwise interfere with the primary magnetic
field and distort the signal generation process.
The Titan's stylus rides at the tip of a low-mass diamond block
measuring 0.08 x 0.12 x 0.5mm. The stylus itself is a Lyra-designed
line-contact, with a major radius of 70 micrometers and a minor
radius of 3 micrometers. We first designed a number of different
stylus shapes based on theory and calculation, and then subjected
the candidates to exhaustive interactive testing. The result is
a stylus that is extremely good at tracking and detail retrieval,
yet offers ultra-low levels of groove wear, has a very good signal-noise
ratio, and reduces the audibility of groove damage.
The Titan uses a compound structure cantilever which has been
designed to increase the propagation velocity and self-dampening
characteristics as much as possible. Consisting of a solid boron
core, an outer diamond layer, and an additional reinforcement metal
jacket, the cantilever's combination of low mass, high stiffness
and low internal resonance reduces overshoot and ringing, thereby
helping to minimize the audibility of groove damage and improving
the perceived signal-noise ratio, even on worn records.
The 5.5-ohm low-impedance signal coils are wound from high-purity
copper over a chemically-refined high-purity iron core, which has
been gold-plated to reduce eddy currents and thereby minimize distortion.
The impedance characteristics remain flat far beyond the audible
range, and the use of high-purity materials reduces both measured
and audible distortions.
The free length of the Titan's suspension wire is ultra-short.
This creates a precisely defined reference pivot for the cantilever,
and plays an important role in improving the conversion accuracy
of mechanical vibrations into electrical signals. The compound
damper system utilizes completely new damper materials that provide
superior tracking, detail retrieval and minimal ringing.
The cantilever assembly of the Titan has been mounted directly
to the titanium body. Intermediate mounting methods such as polepieces
or subcarriers have been completely eliminated. Both the cantilever
and the insides of the body have been shaped so that when the two
components are joined to each other, a double-knife-edge system
will be created, which will concentrate as much pressure as possible
on the joint area and thereby achieving a type of cold weld. This
direct mounting system minimizes the number of mechanical joints
between the cantilever and tonearm, and maximizes mechanical energy
transfer away from the stylus and generator area. The end result
is far less reflected mechanical energy, and therefore significantly
reduced levels of distortion and resonance.
The signal output pins of the Titan are plated with rhodium, a
highly conductive yet tough material that, unlike gold, will stay
intact and retain its superior conductivity, even over repeated
cartridge installations.
The Titan has been designed for ease of use. The body incorporates
threaded M2.6 holes to make it easier to install the mounting screws.
The total height of the Titan is just under 17.9mm, while the distance
from the center of the mounting screws to the stylus tip is 3/8
inch (9.525mm). Henceforth, all Lyra cartridges will be standardized
with these height and mounting-screw-to-stylus dimensions.
Despite that the Titan is a fully nude cartridge, the design of
the stylus guard affords the stylus and cantilever full protection
when the Titan is not being used and also during the installation
process. The slide-on design of the stylus guard makes it easy
to use and minimizes risk to the cantilever when the guard is being
installed.

Cautions: Because of the high body rigidity and direct cantilever mounting
systems, the Titan pumps a significant amount of mechanical energy into
the headshell and tonearm. If the arm doesn't have very high-quality
bearings or a stiff, low-resonance armpipe, it may not be able to deal
with this energy, and the resulting sound may be too forward and bright.
Make sure that the mounting surfaces of the Titan and headshell are completely
clean, bolt the Titan to the tonearm headshell very firmly, and make
sure that everything in the headshell and tonearm structure that can
possibly resonate is screwed-down securely. If that doesn't solve the
problem, most likely the tonearm design is incompatible with high-energy
cartridges.
The Titan should be set up in each tonearm so that the low-frequency
resonance point comes between 8~12Hz. For optimal tracking, the
low-frequency resonance should fall between 10~12Hz.
Due to the high-resolution stylus profile and the extremely revealing
nature of the entire design, the more carefully the Titan is set
up in the tonearm, the better it will sound. If the Titan does
not sound satisfactory in a given audio system, the most likely
problem is improper setup.
