NP D1 DAC clone with enhancement - Page 17

For D1V33, it is less susceptible to oscillation and thus no shielding is required if electrolytic Bi Polar capacitor is used. Personally I like Nichicon BP Electrolytic capacitors as they are cheap and good.

Good news ! Thanks !

The original D1 use 18 bit data mode from CS8414 to SM5842. Thus it is not optimise for 24bit data signal.

I have done an upgrade so that the D1V3 and D1V33 can use 24 bit data file with better results. See link below:

Some update in fetaudio regarding using 96k Fs and AD1862 DAC in D1 platform.

Hi,

I've just started to build your DAC

Is there any build thread ?

Thanks for your nice packaging

I believe everything is in below links:

Hi Spencer,

I am wondering if it would be possible to use an external clock on the D1V33. I read a post (number 4 in this thread) but it was the D1V3. Is it still possible on the D1V33 ?

Actually I'd like to have a masterclock for both the DAC and my CD drive.

Thanks for your halp.

PS : BTW my dac is working, your assembly manual was most helpful. I doubted to be able to mount it but it went smoothly following the instructions

See here : FET Audio » D1V33 with external super clock 256Fs

D1V33 use master clock at 256 Fs. Fs maximum 48kHz for SM5842 and 96kHz for SM5847.

Recently I tried RIFA PEG124 100u/100V on the 4 output capacitors and the sonic performance is very good. Silmic II has been used and it is also better than Muse BP and the sound is a bit silky and soft. PEG124 give the highest dynamics in all frequency and is a very good capacitor for signal coupling in this DAC. Choose the capacitor that suit your sonic taste preference.

Hi Spencer,

I have some LM140LAH lying around and am considering to use them in lieu of the LT1117 since they may be quieter. Is this feasible?
