Hi @iancanada
Is there any difference between your UcBalancer kit and the eBay balancing board pictured in the UcPure mkIII manual? Yours of course have the better connectors and so, but will both board safely balance the ultra capacitors?
Thanks in advance 🙂

You have no problem to use both. But UcBalancer will be much easier and safer to work with a UcPure and will be more durable.
It also comes with all good accessories, no need to source them somewhere else.

UcPureQuadA total mystery to me, but good news!
Yesterday I received my MonitorPi Pro back from Audiophonics. I never had any screen activity on this but it worked without problem at their end. Today I plugged it in, mainly to troubleshoot my distortion problem, and there immediately was screen info! (Nothing had changed for the rest of the streamer in the meantime, except that I added an external on/off button for the Pure Pi II.)
And more mystery followed: I can now play higher resolutions up to PCM384 and DSD512 without distortion.
One thing you learn in this hobby: and that is accepting that one cannot understand everything. But I am happy
Afterthoughts:
Thinking about it, I am extra surprised that I can play DSD512 as I am not using the Amanero board but the internal RPi DAC:
Card 0, ID `DAC', name `I-Sabre Q2M DAC'
Device 0, ID `I-Sabre Q2M DAC i-sabre-codec-dai-0', name `I-Sabre Q2M DAC i-sabre-codec-dai-0', 1 subdevices (1 available)
2 channels, sampling rate 8000..1536000 Hz
Sample formats: S16_LE, S32_LE
Buffer size range from 4 to 131072
Period size range from 2 to 65536
Elswehere in this thread it was mentioned that RPi does not do DSD over the GPIO connection. But apparently it does.
And I forgot to mention two other changes that I made since having the distortion problem: I added a second SC-Pure, the 49 one (not relevant I guess as DSD uses the 45 one), and I am holding down the clocks with Tungsten cubes. I found them a bit wobbly without the help of this extra weight. See pic.
Did the Tungsten blocks cure the distortion?
I am not going to test this as they are now firmly fitted. The case lid has some foam attached that barely touches them, so that they will stay in place even when I put the streamer upside down.

That's really wonderful.
How did you play DSD512 without a USB?
What software are you using? Still through the DoP protocol?
Thanks,
Ian

HQPlayer embedded on GentooPlayer with Diretta host, to GentooPlayer on the RPi as Diretta target. DoP indeed, as Passthru does not work. However see my previous post :-|
Ian, is it possible to power the OPA861 board from the 5v output even though it’s only one rail? Or perhaps power two 5v ucconditioners? Is there increased noise on that rail with the rpi also used?
Thank you!
Hi @iancanada
Thanks for you reply regarding UcBalancer.
Do you have any updates on your StationPi Pro Controller 🙂
Maybe some design criteria you look to implement or prototype pictures perhaps 🙂?
Thanks again

Lucky you, whatever I am trying with ideas from Ian, still having the distortion problem..And more mystery followed: I can now play higher resolutions up to PCM384 and DSD512 without distortion.

As I read later posts, it isn't over yet. :-(
Hello,
Digital audio is a can of worms.
There are to many things that can go wrong. And once it is wrong most people have no clue how to solve it.
And everyone seems to have a problem that is different than the other peoples problem.
Of course having a collection of to many boards with everyone of them with its own manual not in your mothers language written by technical people does not make things easier. Greetings Eduard

Hi everyone,
I am new to DIY audio and new to Ian's audio boards.
Recently I have assembled small Transport Pi Digi streamer with Pure PI.
I have a problem with powering Transport Pi Digi board using battery power from Pure Pi.
Unfortunately I didn't notice that one of the clocks was put backwards before powering up the streamer.
I already got a message from Ian to look at the fuse on Transport Pi Digi. But I don't know where it is. and how it looks like
Could someone show me somehow what am I looking for?
I would appreciate your help.

This is true, I had a problem where i could not get any sound, although every thing appeared to be working, it took me about a day to find out that it was a badly soldered joint. However if i had been an electrical Engineer , I think I would have found the issue in about two Minutes. I did not even think that the issue was in the analogue domain not the digital. With digital circuits you need to be far more methodical in your fault finding, and underneath all of that you cannot ignore the fact that the issue may not be in the digital domain.
Alas not as wonderful as I hoped. The distortion is virtually gone, and that was the reason for my initial euphoria. However, with my ear close to the speaker, I can hear a soft continuous white noise starting when I hit Play with PCM 176 and above, and with DSD. When the music starts I can hardly hear this noise, but it compromises the pristine sound that I am after.
This behavior is regardless whether I use the internal I2S DAC or the Amanero board.
So the behavior w.r.t. distortion has changed. Why? I did make some changes recently, but hardly think they are relevant:
- rewired everything with thinner silver wire (Xangsane)
- added a second SC-Pure (49, I already had the 45)
- added Tungsten blocks on top of the clocks
- added MonitorPi Pro and mounted this to the front of the case using the GPIO extender
- attached an external on/off button to the PurePi II
- attached a ground box to the streamer
Now that I have the MonitorPi Pro working, are there any settings I could try to get rid of the noise? I would already be happy if I could have noise-free PCM192.
