INTRODUCTION
Inspiring the joy of listening
Technical Audio Devices Laboratories, Inc. (TADL) grew from the spirit to discover technologies to perfectly recreate the pure
sound of live performances with uncompromising craftsmanship. We have inherited our philosophy from Bart Locanthi—
recognized across the globe as the ultimate sound technologist—who believed that genuine technology is true to the basics
and that genuine technology places greater importance on sound quality than on technology for its own sake.
At TADL, we are honing our technology to create equipment that reproduces musical sounds that evoke both the energy and
impact of live music.
Main Features
Immaculate preamplification circuit
TADL has developed a preamplifier version of a single-stage, current-feedback amplifier originally developed for the TAD-M700
power amplifier and other TAD hi-fi components, and incorporated it into the flat amplifier section of the TAD-C1000. To
achieve the highest level of complementarity of signals, we have tested the performance characteristics of each FET device
and chosen matching pairs for positive and negative elements for the TAD-C1000. This meticulous attention to detail has
taken the stability of the preamplification circuit to a higher level.
Center-mounted, ball-bearing-supported volume knob
The volume knob has an exquisite look and feel. It is mounted on high-precision ball bearings to ensure an
exceptionally smooth rotation. Its center-mounted design signifies the symmetrical layout of the internal circuits
in the tradition of Evolution Series of hi-fi components.
Perfectly symmetrical circuit layout
To suppress even the smallest amplification errors of positive and negative signals, as well as between right and left channels,
the audio circuit patterns and parts are symmetrically laid out on the bottom chassis. The pursuit of perfectly symmetrical
design does not stop there. We have even gone as far as to lay out two power transformers, the chassis construction, and
rear-panel jacks symmetrically to achieve optimum weight and vibration balances. With these elaborate symmetrical designs,
signals that go through the TAD-C1000 are amplified in a unified electrical and mechanical environment, which contributes to
a sound with a greater stereophonic impact.
Intricate vibration-control design
The heavy, sturdy body of the TAD-C1000 is supported by Evolution Series' signature spike-shaped feet. The minimum contact
with the surface on which the TAD-C1000 sits keeps external vibrations from travelling through the feet and eliminates their
adverse effect on circuits and parts inside the case. Furthermore, two power transformers are each mounted on a 6-mm thick
brass base that dampens transformer-induced vibrations.
High-purity power circuit
To increase the purity of power supply, the internal coil of the transformer is directly connected to the power supply circuit,
minimizing the contact points with lead wires. Moreover, terminals for directly connected coils, mounting terminals for
motherboards, and clamping screws are all made of oxygen-free copper coated with nonmagnetic materials to eliminate even
the slightest magnetic distortions.
The audio and control circuits are each powered by a dedicated large toroidal transformer. The one for the audio circuit has
independent internal coils for right and left channels. This ingenious grounding system ensures perfect symmetry between
positive and negative signal levels and between right and left channels.
TAD's custom-made parts and components
TAD's custom-made electronic volume control circuit boasts ladder-resistance switching that achieves exceptionally precise
attenuation performance and an ultra-low distortion of less than 0.0005% at 1 Vrms input. In addition, the power circuit
employs TAD's custom-made electrolytic smoothing capacitors, as well as large-capacity, ultra-low-distortion film coupling
capacitors to achieve a wider low cut-off frequency range.
