new 2 channel strero DAC board for OPPO 103 ( updated)

I am preparing first 50 units mass production .

 

It is fully functional such as volume control with OPPO remocon, HF filter selection ( can be selected through dip switch )

 

This DAC board can be used stand alone DAC board if +5V( digital), +,-15V ( analog ) power supply is provided.( with DP switch setting , it can receive normal I2S signal ). This function will be good opportunity for those who want supreme quality DAC board as DIY project.

Features.

  1. premium Sabre ESS9018 DACS chip

  2. op amp: OPA1632 and LME49710 (metal can type can be installed ) or user can select his/her favorite OP amps ( interchanble)

  3. unbalanced output with gold plated RCA connector ( optional balanced output is provided)

  4. using microprocessor for user favorite selection HF filter

  5. Volume control with oppo remocon ( enabling direct connection to any power amplifier without pre amp for better sonic results in many case )

6. total ground isolation between OPPO main board and 2 channel stereo DAC section

 7. all 8 of Sabre ESS9018 chip data inputs are used all for 2 channel stereo . ( oppo 105 shares with headphone amp, balanced and unbalanced output )
