@iancanada I have a Gustard R2R with the #1 configuration without the Clock replacement. One odd thing is that when I play a DSD file and then go to a Flac file there is a pop noise. Did you have that happen to your setup? Is this a know issue with the Gustard R2R with Option 1?

Thinking ahead I realize I may need an I2S switch. I have one I2S source and am building two DACs. The first one is the DAC in this thread and the second is TDA154A based. I want to be able to switch signals from one to another. There's this one that's available on Amazon and Aliexpress

Hello all
I would like to request some assistance from this very experienced forum regarding the Amanero & Ian Canada's ReceiverPI DDC.
The proposed stack would be Amanero Combo384 / ReceiverPi DDC -> FiFoPiQ7 -> HDMIPiPro and this would then feed a Gustard R26. My intention is to be able to stream DSD256 to the R26 via HQPlayer. I would not be using a Raspberry PI in this set-up.
My question is this. Can the Amanero Combo384 accept DSD256 if I am connecting it to HQPlayer running on Ubuntu? The documentation for the Amanero Combo384 seems to indicate that it can only do DSD256 using the ASIO driver and this, in turn, means I would need to run HQPlayer on Windows rather than Ubuntu.
@iancanada - would you be able to advise please? Now that you are the official distributor of the Amanero in North America, I am hoping that you can clarify, please?

Hello @elamar
What you are trying to do is not possible with the FiFoPI Q7 & the R26.
In order to use an external clock with the R26 you need to connect an external clock via the socket on the back of the R26 that is labelled "10Mhz In" (something like a Gustard C16 clock unit).
The R26 will not accept the I2S output from the FiFoPI Q7 / HDMIPiPro as an external clock signal.
The reason you get the "ext err" on the R26 is because you have no clock attached to the "10Mhz In" socket on the back of the R26.
Hello @iancanada - thank you very much for your input on the R26 vs the Holo Spring using your DDC stack. This is really useful. I have a R26 and was considering replacing it with a Holo Spring - but now I think I will reconsider.
Couple of questions please:
- What DSD did you stream to the R26? Was it DSD64, DSD128 or DSD256?
- Were you using HQPlayer for purposes of producing the DSD Stream?
Thanks
@elamar
I think I know the reason of you issue now.
You could have set the REF CLOCK to EXT, however the EXT means the external 10MHz reference clock for PLL, not the clock from HDMI cable.
Solution: Please set the REF CLOCK to INT, the error message will be gone. And R26 will take clock from I2S/DSD over HDMI input, the internal PLL will be disabled.
Confirmed on my own R26.
Regards,
Ian
@iancanada why haven't you looked at building your own r2r boards with your skills you will far out do these units... Sell like hot cakes too
How does the r2r compare to a FIFO dual mono active i/v stack with everything running with dedicated ucpures? This is what I'm using and it's damn impressive.

R26 PLL only applies to USB or LAN input, when input from HDMI, COXO, OPT, or NOS, the PLL function will be off and the clock from music sources will be used.

It's hard to beat sc pure FIFO ess dual mono active i/v when everything is running on ucpures, basically the best power supply in the world.
Now an Ian Canada designed r2r DSD 1bit dac board to go with our stack, that will be something!!
@iancanada - could you please come back to me on the question about the maximum DSD rate that the Amanero Combo384 can achieve with Linux vs Windows?
Many thanks
@Gabster 2000 it looks like I'll be feeding my dac build with two UCPure and three LifePO4 Mini 3.3V . I'm keeping the AC transformers in one case and the DAC in the other just like yours. I noticed you used a DB15 cable to connect the two chassis together. What gauge wire did you use? The biggest I could find is 20 AWG shielded in a pre-made cable. I was worried that 20 AWG was to small. What gauge is your DB15 cable?
Currently I connect my transformers directly to the mains. I am employing a wooden board and most likely will take some time porting the build to an enclosure. I want to add an IEC with fuse and switch, something like this. Would appreciate some help on how to install something like this on a wooden board? Are there some L shaped brackets that can be used (but this IEC won't work). Would really appreciate any suggestions.
