DAC PCBs for sale

Diy Audio Folks,

I'm selling PCBs for those who might wish to construct this DAC design.

The design is based around the Burr-Brown (TI) PCM1794 in combination with the SRC4192 and CS8416.

Plenty more details can be found in these links,

If the links don't work (possibly due to too much traffic) contact me via e-mail (email button at the bottom of this post) and I will send the files to you.

My main impression on sound quality is of a smooth and very musical nature. I have worked on various PCM1704 based designs both using op-amps and also using discrete output stages with no feedback loops. For me the PCM1794 design I present here betters them all.

Please note that this should only be attempted by those who are comfortable soldering surface mount devices. It is actually very easy but this is not the project to use as the learning curve.

The price is 80 US Dollars for main PCB, front panel PCB and programmed microcontroller. All other parts can be purchased from Digi-key and Farnell. Please contact me via the e-mail feature of diyaudio.com.

I finally have my own DAC in its case.

Drilling the front panel. The PCB has holes in the centre of the LEDs / buttons. You can do this without damaging the board.
