After the great success the first version Quanghao opens this new group buy to produce a new series of DAC.

ES9018 USB DAC - Hi-Resolution System*

I can support you by email and chat until all will be happy for this project.

I do not take money from the production of these DAC.

Quanghao will produce these modules with little gain to promote this product, in the near future this DAC will be sold as a finished product at about 2500$ - 3000$.

This DAC ES9018 module have these features:

- top performance linear pre-regulator LT1963
- separated fast shunt for any digital section
- separated fast shunt for any analog channel
- remote volume control
- remote mute control
- remote input control
- digital filter control
- microcontroller to remap DAC to share I2S connection with DSD
- Amanero module integrated to have USB input
- Support 44,88,96,192,352,384KHz PCM and DSD to play SACD ISO
- ground isolation from USB module
- On board reference 100MHz Crystek oscillator with a jitter of 0.5psec
- 3 spdif input: coax RCA, Toslink optical and AES/EBU
- optional passive I/V
- 4 row x 20 characters LCD
- 5V LCD
- large dB volume display


This options are available and here the new cost:

1) DAC module assembled and tested with all components
- ES9018 chip,
- Crystek 100MHz top performances oscillator (CCHD-950-25-100),
- 5 shunt regulator
- All digital connectors
- Controller to change volume, input and other parameters
- 20x4 LCD
- Infrared remote command
- Amanero module not included
price 450$

2) Chassie only
price 140$

3) Power supply transformers only, for the discrete output stage you need 3 transformers, for the LL1684 output stage only one.
price 40$ each

4) Amanero module only
price 60$

5) LL1684 output stage only (pcb, Clarity cap, LL1684 Lundahl transformers and connectors)
price 420$ (price for 2 modules L & R)
