Product Description
Introduction:
R2R architecture AD1865 NOS tube version DAC (can support 24-bit input), using all positive power supply, CS8414 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.
