Vacuum tube and digital sound always as an opposite sign in sound nature. P2 is using a traditional Class A amplifier circuitry to perform a vacuum tube sound nature and remove the digitized harmonic in the sound to your ears. It makes your digital music player sounds more warm and soft.
Two build in batteries in series connection to deliver a purify power for whole unit and 17pcs electrolytic capacitors provides an enough dynamic energy. ATC engineering team also used an analogue volume as for a sound level control instead of the encoder; it helps to reduce the sound distortion.
