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.
Features
ultra-high c/n* ratio Master clock featuring uPcG**
Reduction of the total amount of master clock jitter has been previously suggested as a means of attaining even higher levels
of sound quality, TAD Labs has taken this a step further, focusing on reduction of jitter in the low-frequency sideband ranges
relative to the center frequencies, and to that end, a new Ultra-high-Precision Crystal Generator (UPCG) has been developed.
Based on technologies developed for high-speed digital base-station relay facilities, the master clock with its dedicated
oscillators and high-purity conductivity deliver the ultimate performance demanded by a CD player, allowing it to reproduce
to perfection the signals engraved on the disc.
*C/N: Carrier-to-Noise ratio
**UPCG: Ultra-high-Precision Crystal Generator
twin Differential D/a converters
Twin Burr-Brown digital-audio converters (192 kHz/24 bit) are connected in parallel for improved audio performance in all
metrics, including S/N ratio, linearity, dynamic range, and distortion. These features allow even delicate audio signals to be
played back faithfully, creating a greater degree of breadth in musical reproduction.
independent Power supply
The TAD-D600 features a power unit housed independently from the CD player itself. By separating the two assemblies in this
way, the harmful affects of extraneous vibration and magnetic flux leakage from the power unit are eliminated.
Further, the audio and digital sections feature independent toroidal transformers with super-powerful 400 VA performance (on
a par with the performance found in a power amp), producing the high response necessary to follow virtually any signal, and
achieving both high power and low noise.
High-rigidity construction with Low center of Gravity
In order to suppress the deleterious influence of external vibrations, a highly rigid cast-aluminum chassis with three-point
suspension has been introduced. Placement of the massive heavy base has been designed to lower the center of gravity,
thus further reducing vibrations. These design elements have made it possible to reproduce music signals with great stability
while avoiding the vibration caused by speaker pressure and other sources.
Dac Mode
With its high-precision D/A converters and high-purity master clock oscillators, the TAD-D600 demonstrates equally high
performance as a D/A converter unit. A sampling rate converter and ultra-high C/N master clock for reclocking make possible
high-precision conversion.
