If you own the incredible Cayin N6 II portable audio player then you are able to completely replace the audio motherboard with a different unit in order to change the overall sound signature of the player. The T01 is designed around the PCM-1792 DAC chipset from Texas Instrument. Each Audio Motherboard deploys two DAC chipset in current output. The fully differential amplification circuit compromise of 4 channels I/V Converter and four OPA162 as headphone amplifier in parallel, offering up to 245mW into 32Ω unbalanced and 530mW balanced. The Volume control of T01 were conducted in analogue domain through two PGA2311A, digitally controlled analogue volume control microprocessor.
T01 is a tribute to N6, the first Cayin DAP that dated all the way back to Dec 2014. This is a significant advancement from our N6 and N6mod audio circuit. 01 will decode PCM upto 24Bit/192kHz and DSD64. It can provide upto 8.5 hours continuous playback on single-ended phone out, and around 7.5 hours on balanced phone out.
