We have had some issues with the DAX0 dac where the cs4398 chip has burned. We have been unable to confirm exactly what has been the cause when this has happened, but we believe it is related to static electricity. We have stopped selling the dac for a while while investigating, and we have come up with a ESD static electricity protection that we believe might help avoid the problem.
The diodes should be soldered close to the connectors (RCA). We have a few of the dxco left in stock. It is recommended to install the diodes, however these are not include these in the kit.
The dac discussed here: http://www.diyaudio.com/forums/digital-line-level/192353-hifimediy-direct-out-cs4398-dac.html
The DAC from Hifimediy is designed around the idea of putting all the effort on the digital and D/A conversion side.
Using it for 1 month now and it is incredible. There is no comparison possible with my previous DAC (iBasso D10 Cobra).
I can now use fully my system, french speakers (Pierre Etienne Leon MIV) and french integrated amplifier (Atoll IN100se).
With Obbligato Film Oil caps, I have a very nice Analog sound, with lots of depth and very accurate. Incredible with some Qobuz – Studio Master files (24 bits master files) !
And last but not least, this DAC is fully upgradeable when you’ll need it ! Infinite possibilities for the output (Tube based, Lundahl transformers, caps) and I2S, NOS, more inputs, balanced outputs.
Well, just buy it, you can’t regret.
