As you know, Ukraine is in a difficult situation. However, we continue to work. Delivery of goods takes place through Poland, from Poland air delivery around the world. We ship once a week. Expensive items will be shipped only by courier with insurance! A percentage of the sale goes to help the Ukrainian army. Buying from us, you help our country to survive and win. Thanks! Please note we do not accept orders from Russia and the Republic of Belarus. These countries are forever closed for our products.Also, we no longer provide any technical support to the owners of our devices from these countries! Here is the custom made abbasaudio DAC 4.1 with the tube single ended output stage, in a metal hausing with the wooden front panel. AC: 230v ( can be switched to 115v) As far as I know, before that, there was no DAC model on the market that would use a rectifier tube in the digital section. We do it. Attention! We do not use the mute output relay! The device requires warming up for three minutes, at this time various unpleasent sounds are possible, keep the volume at a minimum! Further, the device can be kept on around the clock. The output stage based on 5687 and 6X5 tubes. Power cord is not included! We dont use modern high-end ultra pure copper or silver wires inside DAC.We used only an old vintage copper wires taken from old sound equipment. Stranded wires are composed of different varieties of copper strings on a certain principle that leads to the devices 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 4.1 features: 1. EZ90 ( 6X4) tube rectifier in digital section 2. CS8414 SPDIF receiver 24/96. 3. Shunt voltage regulators based on germanuim transistors. 4. The boards covered with gold and a special varnish for best sound.5. 4.5v rms 0db output level 6. Hand made multistrand wire was used in internal wiring. 7. I/U convertor based on the low noise germanium transistor. As a consequence of this fact, an excellent reproduction of quiet sounds,at -60..-80db level. 8. PIO output capacitors . 9. Shortest signal path. 10. NOS mode(non oversampling). 11. Genuine PCM58 made in japan. 12. A separate power transformers for digital and analog sections. 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! Dimensions: 440X200X100 Tubes included: 1. 5687 2. EZ90 3. 6X5This device worked in our workshop for some time. There is a small scratch on the back panel. This copy is the last in the series. Discontinued.
