Very happy, hi-fi quality
Hello, the digital volume control has succeeded in its processing very high quality. The circuit itself and your components are also very high quality. BUT ... after about 1 hour of operation (CD input), the right channel suddenly fails? First only quieter and quieter sounds become louder after a while. The whole thing happens without any changes that are carried out on the device? If such a disturbance occurs and you change in the connection shortly the volume, then the disturbance is gone again. Since I am sure that in my copy no defective components are the cause. Is it rather the circuit or the chip - HIFI NJW1194 ansich. Here is a revision of the schematics necessary. I myself have been doing audio tuning for the last 8 years so I can only give 2 stars. Best regards Erik
