Attention guys I don't hear any kind of pop click using abraxalito 4th passive filter when I change formats between DSD & PCM or viceversa, only a pop when power on I guess because I don't use a bleeder resistor after the output capacitor. Attached schematic.

Hi Merlin,
I got two i2s isolating boards from Diyinhk laying around for month now. I read in the thread that you are using these also. What isolator chip are you using on those board and do they make a difference with the amanero?

Hi Klaus,

Finally don't used the isolators because introduces noise. Capacitors used Russian teflon FT-3 0,1uF: one for C3 and two in parallel for C2, inductors used Janzen wax coil adjusting the value needed with an LCR meter.

Greetings
Felipe

Thanks Felipe,
Looks like you are using the SE version of the noDac.
What would the schematic look like for the differential version?
Did you wind L1 and L2 yourself or are those stock parts?
Where is C2 located on the above schematic?

Greets,
Klaus

Hi Klaus,

Yes SE, sounds far better than balanced using chips (attached schematic bor balanced isn't mine I guess is published in this thread).

No I didn't wind my own inductors I bought Janzen Wax coils, I bought 0,22mH and take off several turns till measures 0,205mH and the same with 0,56mH taking of several turns to reach 0,5mH

I'm sorry isn't C2 it's C3.

Cheers
Felipe

I'm using Daphile as player so Linux based.

Try this one:

firmware 2005be e Cpld_for_1081

If doesn't works for you, try this other:

firmware_1099c e cpld_for_1080

Is there any advantage to those firmwares?

Are the latest firmware Linux recommended by Dom of Amanero, he is developing the final version of firmware for Linux for DSD512.

Windows guys the recommended firmware by Dom of Amanero is DSD512x44x48.

I received the Dom's advice by email one week ago.

Cheers
Felipe

so is the ''white noise'' some/all people are/were experiencing still a mystery?
I tried using Bisesik's current out DAC trafo as a test with DIYinHK interface, primary resistance of 10ohm is probably too low but there is sound and it was drowned in that ''white noise''.
There is only the trafos own filtering here, but as we know DSD noise is above audible spectrum so did not try adding any other filtering

replacing trafo with 1k resistor and 10n cap brought noise way down to tolerable levels but it is still an issue for proper use with headphones.
Even with the noise the sound is pure magic and instantly appreciable, there is no going back to a normal dac ever again, completely outclasses 9038Pro/Q2m DACs ive used in resolution but the real ''magic'' is how pure and natural it sounds...

also the noise increases with higher DSD rates in my case
