Component pictures

Two years and after more than 10 times modifications, Xuelin took care just for a little bit better.

Dual ES9038Q2M DAC

One is not enough, then two! ESS9038Q2M provides 129dB S/N and 120dBTHD +N. The two-chip in parallel is a basic respect for the audiophile spirit.

SA9227 Asynchronous Clock

The conventional decoding scheme uses a 12MHz crystal frequency division, which is not divisible by 44.1 and 48K, and only an approximate value can be obtained at the top. This is where the sound fragmentation comes from. We use 45.1584M/49.152M asynchronous dual clock, corresponding to 44.1K and 48K precise decoding.

CD format: 45.1584/44.1 = 1024 k

DVD format: 49.152m /48K=1024

It is no longer difficult to make bricks without straw

Full-architecture portable decoding, comes with 2900MAH power supply, you don't have to take power from the mobile phone and worry about battery life, but can only use micro-power DAC and CLASS D amplifier.

Powerful soft control system

XUELIN put in nearly 500 hours of code development, and almost no decoder has ever been so detailed and multifunction.
