Default looking for DAC

hello. can anyone suggest a good DAC kit/or PCB that has I2S input, descret outputs and not too expensive? (not buffalo)
this is going to be used as a internal DAC in my CD player. (DIY)

Hi AudioSan
Don't know if it's accurate concerning discrete outputs, but have a look at the Opus from TPA. It could handle directly I2S input.
Be careful considering your CDPlayer fs rate, check your chip
From what I've read, fs must be 64... (FS = BCKI : Bit Clock / LRCI : Left-Right Clock)
Cheers

Forget to mention that Opus works in "slave" mode, waiting for I2S clocking from I2S source.

Hi AudioSan
I haven't seen any OPAmp on Opus board... (I've got 2 units, maybe one for sale soon)
Could you point me where they stand ?
Out of stock...

Have a look there :

Push a PM to Subbu for PCB, maybe he could provide you a set.
