THE EVOLUTION SERIES C2000 PREAMPLIFIER
REVEALING THE CONCEALED BEAUTY OF SOUND.
TAD steps out from the audio mainstream with the TAD-C2000 preamplifier, an exciting new frontier in evoking the essence of sound.
The #1 goal of the TAD-C2000 is to reproduce music faithfully, and superior components make this possible. Using technology developed from the D600 disc player, a custom developed UPCG** quartz oscillator provides a precise, stable and ultra-high C/N* clock signal, thoroughly reducing phase noise and enabling sound reproduction with unprecedented purity.
* Carrier to Noise Ratio
** Ultra High Precision Crystal Generator
In order to achieve the best sound quality from music, files transferred from a PC, TAD developed the Asynchronous USB Transfer Engine. In contrast to the normal synchronous transfer method, the asynchronous method adopted by the TAD-C2000, controls the data transfer on the receiving end using a high quality clock, and resulting in a high-precision PCM signal free from clock jitter created in the PC or transfer stages. The ultra-high C/N master clock UPCG equipped D/A converter converts it to precise, high-quality music signals.
*The USB playback format depends on the PC software. See your PC manual for PC settings.
In order to achieve accurate signal transmission, the TAD-C2000 maintains a fully symmetrical design, right down to the circuit topology, the PC board and the wiring. The analog circuitry is fully balanced from input to output. These circuits utilize separate boards for left and right channels with identical wiring lengths for each, achieving identical L/R circuit symmetry with Dual Mono Construction.
In order to prevent vibration from affecting sound quality, the chassis is machined from a solid piece of aluminum to eliminate joints and provide a stable, heavy and mechanically grounded platform. The components are directly attached to further limit any chance of noise-generating vibration. Even the feet, made of cast iron, are supported at three points to the chassis for improved stability.
TAD put a great deal of effort into the design of the networks to seamlessly intergrate the drive units into a cohesive whole. To eliminate any effects from magnetism and vibration due to the CST and bass drivers, the network filters are located outside of the cabinet. Installed within the high rigidity aluminum base, these networks are isolated both mechanically and acoustically from the influence of the main enclosure, ensuring maximum resolution.
● The D/A converter uses Burr-Brown PCM1794A chips in a twin differential configuration.
● The circuitry and power supplies are completely isolated between digital and analog sections, ensuring low noise.
● A 70µ copper foil PCB lowers losses from board wiring, permitting accurate signal amplification.
● The power supply utilizes a high capacity toroidal transformer for a powerful, yet responsive sound.
