take a look on my dac

[ghetto]

All I have to say is:

Are you an engineering student Takashi? That is amazing work!

 

[machinow]

Very Good

Amaizing!
So many Capacitors?? Why, in fact? /First time I think the PSU is on the DAC board....🙂 This is not a commersial design, definitely

Congratulations 🙂

yes, the psu is on board, but i want to have a better psu, so i add external psu.

yes i am gurated in electronic and i am very interested in diy audio, specially DAC!

and i am planning the next dac using ad1955!

AD1955

Good, I plan to use it too, but u may be faster than me in the design - I have to study some more things now...🙂
The great problem - in BG I can not find low jitter Clocks yet.....
Good Luck anyway...
