Use the ES9038PRO

ES9038pro is ESS's flagship DAC audio decoder chip, is currently able to see the highest performance index DAC chip, the DA9.1 DAC use ES9038pro.

Have enough experience enthusiasts know, DAC chip is only a machine foundation, the most critical is the external circuit design and adjustment, in order to achieve the use of ES9038pro and get treplay effect, Melokin uncompromising around Circuit design, a total of 11 groups of low-noise regulator circuit, the reaction of fast, ultra-low noise power for best sound 


Redesign high quality clock

DA9.1 redesign the low noise power supply with a low noise and low jitter clock, ensure a vivid natural sound detail and precise stereo sound field while also having good musical aesthetics.

and The package of crystal oscillator is directly compatible with CCHD-575 or CCHD-957、CCHD-950, and it can be replaced directly according to your preference. (You can own replace it)

The Headphone Amplifier output impedance can be adjustable

• In order to meet your more headphone needs,and better drive a variety of different headphones，it has an adjustable headphone output impedance.
• You can adjust the headphone amplifier output impedance through the buttons on the panel.
• and You can Adjustable it to ≈0ohm, ≈10ohm, ≈120ohm.
