Abbasaudio offer the custom made DAC 1.0SE with the tube single ended output stage and the tube master clock.The device is assembled in a metal hausing with the black wooden front .It is "plug and play" device. This device was built in a single copy as an experimental product. DAC has DHT (direct tube heated) tube clock based on 5672 DHT sub miniature output pentode. This original technical solution is not encountered in industrial audio equipment.

The device is based on the burr brown PCM56P-K chip.
"K" means selection :less distortion at low signal levels.

We used the best components selected in a special way to get a perfect harmony.
This choice is not random but the result of a careful and long term hearing examination.

We dont use modern high-end ultra pure copper or silver wires inside DAC.We used only an old vintage copper wires taken from klangfilm ,telefunken,siemens sound equipment. Stranded wires are composed of different varieties of copper strings on a certain principle that leads to the device's ability to transmit the subtlest musical nuances.
We believe that it is the only way to recover the lost life in the recorded music.

DAC 1.0SE features:

1.Tube clock (5672 DHT pentode, VALVO factory,1958 ) with he separate voltage stabilizer
2. CS8414 SPDIF 24/96 receiver and DIR9001 24/96 receiver as option
3.Shunt voltage regulators based on the germanuim transistors.The scheme has been improved and has a superior thermal stability.
4.Vintage and modern audio components are used:allen bradley,philips,telefunken,ROE,
Black Gate (2pc F series,2pc PK series),panasonic pureism, Audio note standart (4pc),Audio note Kaisei (1pc)
5.Board covered with gold and a special varnish for best sound
6.Stranded wires composed of vintage copper wires taken from klangfilm,telefunken,siemens sound equipment
7. I/U convertor based on the special gold plated low noise vintage transistor. As a consequence of this fact, an excellent reproduction of quiet sounds,at -60..-80db level
8. PIO output capacitors SIEMENS from 60th
9.Shortest signal path, the tube output stage with the low output imphedance (5687,EZ80).
10.NOS mode(non oversampling)
11.Genuine PCM56P-K burr brown chips. This ancient multibit chip was used in many professional devices and it provides a sound reminding the tape recorder.
Chip demonstrates outstanding musical abilites and very low distortion.

12.Separate power transformers for digital and analog sections.

15.Telefunken choke from 30th in the 5687 power supply.

The device has an incredible tonal purity and clarity.The result of our efforts are the deep, accurate bass and the extremely smooth, soft, like analog sound!

Output: 2.5v RMS (1khz,0db Full Scale)
