@LongLong00 you need to enable 16 to 32 bit conversion in order R26 to accept the input. Please see FIFO Pi Q7 manual page 10. I've been through that with exactly the same equipment.
Thank you so much, now it's going.
Is there a way that the stremer does not take a break when switching track to track and then clicks?
When I hear a mix cd, this is going through in one.
Now there's a break between everyone track and it's cracking in the streamer. ?
or Pink Floyd:the dark side is one track. Now make a brak vom track to track

@LongLong00 not sure it will cure your issues for sure but the solution may be on FifoPi Q7 manual page 11.
Since I didn't get any feedback on which approach to use for the power supplies, I've decided on my option 2.
iFi SMPS for RPi 4
LinearPi + UcConditioner for IsolatorPi II, HdmiPi Mk II
UcPure (1.5A) for ReceiverPi DDC, FifoPi Q7 Dirty side
UCPure (3A) for FifoPi Q7 clean side.
UCPure (1.5A) charging for HdmiPi Pro II
UCPure (3A) charging for ES9038Q2M DVCC/VCCA
UCPure (3A) for ES9038Q2M AVCC
2x UCPure (1.5A) for OPA861
I have a custom Toroidy Supreme Audio 400VA transformer which has eight secondaries (one for a Linear Pi, and seven for UcPure supplies). I'm going to mount this on a platform spaced above the chassis bottom plate so that I have room for the IEC connector, backpanel rocker switch and fuse under the transformer.
I've designed a power controller PCB which will also sit under the transformer.
This PCB has a soft-start circuit which will engage when the back-panel rocker switch is flipped. The transformer will then be connected to the LinearPi and UcPure supplies, but the only supply that will be "on" is the UcPure connected to the FifoPi Q7 clean side so that the oscillators are powered up all the time.
The PCB also includes a toggle controller for a front-panel push-button, and has output to illuminate the button LED when activated. When the streamer/DAC is turned on using this button, the LinearPi will turn on immediately, followed about a half second later by the rest of the UcPure supplies (which use the daily chain control signal to activate them), and then the iFi SMPS driving the RPi will activate another half second later. I can adjust resistor values to change the delays if necessary.
The PCB also includes a circuit to connect the signal star ground to the chassis ground using a resistor/cap/diode bridge in parallel.

@NeoTheOne you don’t need a 3.3 vdc on the XO J4 on the DAC, if you remove crystal and connect the MLCK from the FIFO.
@NeoTheOne and i’m running the OPA861 on 2 lifepo mini 3.3vdc and the DAC on 2 shunt reg from Tentlabs with 2 7vdc PS from diyinhk, the FIFO is supplied from Purepi.
It looks like you may be sharing the transformer secondaries between multiple UcPures. Each of these needs a separate secondary coil, as does the Linear Pi.
@Jaytor IIUC, according to the images in the project page these transformers seem to have independent dual secondaries?
Also the transformer used by @Gabster 2000 in his videos [1][2] seem to suggest that those transformers can also be used in dual secondary configuration?
@NeoTheOne - That may work, but the specs on this transformer indicate that all windings should be engaged. With the UcPure, there is no current draw from the secondary most of the time, so you will likely have situations where the current draw from the secondaries is significantly unbalanced.
But since Gabby (sp?) got away with it, you should be ok. This might result in more than typical mechanical hum/vibration though. Are you planning to mount the transformers in a separate enclosure?
EDIT: I see that Gabby used a different transformer, although the Triad transformer specs also indicate that the secondaries are not designed to be used independently. It seems that other builders have gotten away with using them to drive UcPure supplies though. I think the most likely risk is increased heat and vibration, but I'm not much of an expert on transformers.

Eventually yes. But for now I'll separate them on different wooden board and use something like these brackets to cover the transformers.

Looks absolute correct 🙂 No sync to add to linearPi though. It is always “on”. I would assume you would also use the LinearPi to feed the dirty side of Q7?
Personally I wouldn’t add 3 x UcPure to the DAC.
I did feed my es9038 mk2 with three separate 3,3v rails from a LifeP04. I didn’t have noticeable that much of improvements, but that just me. The UcPure is also a better supply so maybe more to gain…

How to mount toroidal transformer on a wooden cutting board? I'm planning to start with wooden cutting board for my dac build to make things a little easy for me. But I'm not quite sure how to mount the toroidal transformers on the wooden cutting board. It seems there are a few mounting brackets available on aliexpress but wanted to check here first if there are some good solutions that already exist.
I want to make sure the transformers are secured on the cutting board.

Hello everyone!
I've owned a few IAN Canada devices for a few days now, I see that, lots of people knows His devices very well, so I'm counting on your help and knowledge.
My kit :
1. PurePi II
2. FifoPima 1.5
3. transport Pi AES
+ Raspberry pi 4, with with last version MOODE software installed
I had a lot of problems to configure IANs transport (yes Im familiar with all instruction documents
)
Maybe you will be able to help me.
1. What drivers from Moode software are best to use with Transport Pi AES. Generic drivers doesn't work ( I2s, Hifibery), lots of misinformation in various threads even here on forum
After my own testing I noticed that Hifibery DAC+, HIFi DAC+ drivers work, even for Proto DAC 1387x8,
Are there any preferred ones? The best?
Something else then listed above?
2 question more important.
I have several different DACs at home, the IAN Canada kit was supposed to be used as a digital transport( Tidal streaming mostly), but my two DACs based on TDA1541a , such as Orchid, don't work with the IANs set. There were no problems with AlloDigione. With other DACs everything is OK.
Is there any special configuration? Is there something I need to pay attention to?
Jumpers are moved, tried 3 different sets of clocks ( 22/24, 45/49) and situation is still the same, setup is ok for My Holo Spring, DAC based on AKM 4497, but not for my 1541A, ....no sound at all....
Sorry for my English, hope what I wrote is understandable
Thanks in advance
Thanks, regards
