The TAD D700 delivers a new era of musical reproduction
TAD’s relentless pursuit of pure sound has not rested with the TAD-D600 CD/SACD player, which was introduced in 2010 and has since won critical acclaim for its uncompromised approach to delivering sound in its purest form. In designing its successor, the TAD-D700, our engineers have taken extra steps to further refine the already great disc player by eliminating elements that might otherwise degrade the purity of sound. The Ultra-High Precision Crystal Generator (UPCG), TAD’s proprietary master-clock technology, has been upgraded to a third-generation that boasts even greater precision. The post digital-to-analog conversion circuitry has been polished to generate even more accurate and dynamic audio signals. The redesigned chassis provides even greater sturdiness with a touch of Japanese artistic elegance. All these refinements and engineering marvels incorporated into the TAD-D700 combine to reproduce every minute detail of original recordings without adding or taking anything away in order to bring alive musicians’ outburst of artistic expression or music producers’ creative intentions.
An important factor in the quest to improve sound quality is the ability to control noise-causing vibration. To this end, the D700 has a die-cast aluminum chassis with high-vibration absorption performance. Inside, a heavy 6mm thick copper-plated galvanized steel plate further dampens vibration and lowers the center of gravity. This two-layer structure ensures high stiffness and low vibration to greatly reduce any impact on sound quality. Additionally, the copper plating contributes to lowering the ground impedance, improving the S/N ratio.
True to TAD’s long-held philosophy of delivering artistic expression in music as it was originally performed, the D700 incorporates a digital-to-analog conversion technology that boasts the highest level of precision. As the clock performance makes a crucial difference to the precision of D/A conversion, TAD engineers have spent years developing a new master clock for the D700. The fruit of their meticulous efforts is the Ultra-High C/N* Master Clock UPCG, which greatly reduces jitter in the frequency bands around the clock center frequency. Our original approach to engineering based on theories and real-world testing makes it possible to bring alive the purity of musical performance.
In designing disc players capable of providing the most accurate sound reproduction, TAD has been focused on achieving greater C/N performance by reducing jitter in the lower frequency sideband ranges relative to the center frequencies. With the D700, we have taken an extra step by incorporating an oscillator with an SC-cut crystal to reduce phase noise even further. This oscillator was jointly developed with a crystal manufacturer and has a minimum level of temperature deviation for oscillation at room temperature. The upgraded third-generation UPCG with a ultra-high C/N master clock is responsible for smooth and dynamic reproduction of music with superb spatial characteristics. The oscillator delivers consistently high C/N performance over an extended period of time and operates reliably and with low power consumption.
Parallel-connected twin differential D/A converters with Burr-Brown PCM1794A DACs
Two Burr-Brown PCM1794As, widely recognized as best-in-class DACs, are connected in parallel—one for each channel—in a balanced configuration. This improves audio performance in S/N ratio, linearity, dynamic range, and distortion. In this design, audio signals are transmitted in their purest forms from the D/A converters to the subsequent analog audio circuit, which results in a faithful reproduction of even the most delicate music nuances and brings dense, finely textured sound.
Using pressure-sensitive rather than capacitive touch keys and static light-mode LED displays virtually eliminates the impact of high frequency noise on sound quality. Digital output (up-converted to 88.2kHz sampling frequency) exceeds the CD format performance capability for high-quality sound reproduction.
