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.

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:

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?
