C1000 Features At A Glance:

Preamplification circuit

TAD labs has developed a preamplifier version of a single-stage, current-feedback amplifier originally developed for the TAD-M700 power amplifier and incorporated it into the amplifier section of the TAD-C1000. To achieve the highest level of symmetry of signals, the performance characteristics of each FET device pair are matched for positive and negative elements providing exceptional stability of the preamplification circuits.

Volume control

The volume knob is mounted on high-precision ball bearings to ensure an exceptionally smooth rotation. Its center-mounted design is said to signify the symmetrical layout of the internal circuits in the tradition of Evolution Series of hi-fi components.

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 printed circuit boards (PCB’s) and parts are symmetrically laid out on the bottom chassis. This balanced design concept extends to the two power transformers, the chassis construction and rear-panel connector symmetry all helping to achieve perfect channel balance. With these elaborate symmetrical designs, signals that go through the TAD-C1000 are amplified in a homogeneous electrical and mechanical environment, all of which is said to “contributes to a sound with a greater stereophonic impact”.

Vibration-control

The heavy and rigid chassis of the TAD-C1000 is supported by the Evolution Series’ signature spike-shaped feet that are said to minimize the level of external vibrations traveling through the feet, reducing their adverse effect on circuits and parts inside the case. Internal transformer vibrations are damped by mounting the two power transformers on a 6-mm thick brass base.

High-purity power circuit

Dedicated separate toroidal transformers power the analog and control circuits, having their lead out wires connected directly to the power supply circuit in order to minimize resistive contacts. With the audio toroid supporting two independent windings for the left and right hand channels.

Terminals used for other connections such as; coils, mounting terminals for motherboards and clamping screws are all made of oxygen-free copper coated with nonmagnetic materials to help eliminate even the slightest magnetic distortions. With the carefully engineered grounding system being said to; “ensure perfect symmetry between positive and negative signal levels and between right and left channels”.

Custom components

Many of the C-1000’s components are custom made for TAD to include; custom-made electrolytic smoothing capacitors, as well as large-capacity, ultra-low-distortion film coupling capacitors to extend the lower frequency range. The volume control features ladder-resistance switching that achieves precise stereo attenuation performance and an ultra-low distortion of less than 0.0005% at 1 Vrms input.

System Control

Signal selection, control and menu access are avilable using the front panel buttons and volume control and by the supplied CXF 4096 remote, both in conjunction with the front panel display. Additional remote control is avilable using the Master/Slave 12VDC triggers.
