D-09
Real advanced DAC, despite its modest price
D-09 (or “Pebble”, as it was internally referred to during development) is a D/A converter that makes traditionally natural and enjoyable sonic qualities of Audial DACs more affordable than ever.
Due to its four inputs (one USB and three S/PDIF: true 75 Ohm BNC, RCA and optical Toslink), a D-09 DAC is also a natural choice for anyone seeking for cost effective but quality center of the audio system, a place that nowadays gets taken rather by the DACs than by classic preamplifiers.
Two PLL modes
Audial is proud to offer D-09 as a first device of this kind that lets user choose between two PLL modes: traditional one, which locks on the S/PDIF data, and another one that locks on the S/PDIF frame preamble, which does not vary with data, and is thus able to significantly suppress data related jitter of suboptimal S/PDIF sources.
Galvanically decoupled USB front end
The D-09 USB front end is transformer coupled to the rest of the unit, so source PC gets never galvanically connected to the audio chain. A PC integration into the audio system becomes this way easy and trouble free. In addition, a D-09 has an S/PDIF output too, so it can be also used as a USB to S/PDIF converter.
Discrete, zero feedback, A class, highly linear output stage
D-09 analog output stage is far beyond anything previously seen not only at this price range, but also way above. D-09 output stage is a discrete circuit comprising two transistors at signal path, and it applies no global feedback - yet its linearity is 0.008% at full level, and 0.003% at -6dBFS! In addition, all the supplies are using discrete, zero feedback, low noise regulators. So, there are no opamps, and no three pin IC regulators inside!
The other D-09 main features are:
● Multibit D/A conversion (Philips TDA1387 DAC chip)
● Non over- and non up-sampling, for no compromise transient response
● High quality parts - toroidal mains transformer with internal electrostatic shield, Schottky rectifiers, Allen Bradley signal resistors, Panasonic FM and PPS, and Rubycon ZA and Black Gate N capacitors
● State of the art PCB layout
● Solid and compact machined and brushed aluminum chassis with maple sidewalls, and with all the markings engraved
