Description

The DAC 8 DSD

Fundamentally our new DAC 8 DSD is capable of doing everything necessary to convert every form of digital source into analogue signals at the very highest quality, including DSD right up to the highest possible resolution. We have again further improved the unit’s outstanding pre-amplifier, and incorporated a volume control of fully analogue construction based on High-End Melf resistors. The “State of the Art” output stage is of fully symmetrical design and discrete construction. Its impedance is very low, and it is equipped with symmetrical(XLR) and asymmetrical (RCA) outputs. These features make the DAC 8 DSD more than just a High-End converter: it is also a High-End pre-amplifier of supreme quality.

The seriousness of our claim that the DAC 8 DSD is one of the world’s finest high-end converters can be judged by the fact that we employ two separate, sophisticated mains power supplies for the analogue and digital sections. A volume control is another unusual feature in a DAC, but it makes good sense if the user wishes to install active loudspeakers, or employ the DAC 8 DSD as a pre-amplifier in conjunction with external power amplifiers. The volume control is of highly refined design, and exploits analogue control elements down to low volumes, as they avoid any loss of dynamic quality even at low listening levels. Two gold-contact relays are provided to by-pass the volume control, i.e. it can be removed entirely from the signal path when not required.

 

Technology

The core of the DAC 8 DSD is the converter. As in our high-end players this device also employs the superior quadruple arrangement with eight 32-bit converters from Burr-Brown in a double symmetrical circuit. This circuit provides perfect compensation for non-linearities, and the residual background noise – which is excellent in any case with the 32-bit converters we employ – is reduced by approximately a further 6 dB. The result is a dynamic performance which is hardly capable of improvement, with a perfect “black level”, extreme linearity and freedom from distortion, even in critical passages and the most minute musical details. Oversampling is carried out by a modern 56-bit signal processor, for which T+A has developed algorithms specific to our equipment, offering perfect timing characteristics.

Oversampling is carried out by a modern 56-bit signal processor, for which T+A has developed algorithms specific to our equipment, offering perfect timing characteristics. They are based on Bezier polynomials: Bezier interpolation and Bezier / IIR combination. A standard FIR filter and a short FIR filter are also provided. These options make it possible to select the optimum sound quality to suit the individual piece of music. The DAC 8 DSD can even invert the absolute phase of the audio signal at the digital level, and thereby correct material recorded with incorrect absolute phase.

For the purpose of handling DSD data which can be supplied via the PC-USB input we have developed a unique, dedicated converter: the T+A True One Bit DSD Converter. This is of fully analogue construction and constitutes a genuine one-bit converter, since – unlike other manufacturers – we did not want to use the DSD mode of a PCM converter.
