Product Description
R2R Architecture AD1865 NOS Tube DAC Board With 6N11 + 6Z4 Tubes
This list is for one assembled and tested DAC board, include the 6N11 and 6Z4 tube
Works Voltage: AC170V 50mA X 1 AC9V 500mA X3 AC6.3V 1.6A X 1
(We have the power transformer available. if you need. Please contact us.)
Use Tube: 6N11 and 6Z4
Input : COAX
Output: Stereo L and R
PCB Size:138mm*120mm thickness 1.6mm
With tubes the max height about 80mm (incldue the Copper pillar height)
R2R architecture AD1865 NOS tube version DAC (can support 24-bit input), using all positive power supply, CS8412 receiving, AD1865, passive iV single-ended 6N11(6922) output, 6z4 rectifier buffer. Compared with other non-R2R decoders, the 18-bit AD1865 of the R2R decoding chip has deeper bass dive, more bass overtones, and the sound does not float. NOS has stronger jitter immunity than oversampling and is less affected by time base jitter error distortion. NOS non-oversampling decoding is more realistic and more flexible than most decoders with digital filters, while general oversampling decoding uses digital filters It is easy to appear the sound beam spread and cause the playback sound to spread unreal. The tube audio output makes the frequency response more balanced, the sound density is high, and the analog taste is further enhanced.
