just cut them 🙂@iancanada
Need clarification.... while stacking the cards (between HDMii Pro/AES & FifoQ7) I see soldered material of HDMI/AES board J3 bottom side is touching Q7 card J3 connectors. attached pics....
I think they should not be touching and it's not safe? Shall we need to reduce the length of the excess solder to have gap? or is this by design and ok to continue?
Please advise.

Don't forget the FCPGA DAC, almost all the "best" DACs on the market use them, the point is to make great hardware that you don't have to change for years, but just reprogram the way you want it to sound.I second @zabloc request a dual ES9039PRO and Akm would be awesome I know the 2x ES9039PRO would be expensive due to the 2x chips alone are worth over $200 but when we are at this level most of us would love to go for it.
A lot of us have dacs that do not benefit much from a streamer alone like the Denafrips and many others as they always reclock the signal.
And yes, it is not as simple as it seems. But if and when Ian did something like this, I think It would mess up the accounts of the big players quite a bit.
Please just cut the pins if they are too long.@iancanada

ES9039PRO or ES9039Q2M are on my R&D list.@iancanada
Ian, don't waste your time on the forum and make us new hardware 😎
What I would like to see in the future (and I think others too) is 2 versions of the DAC HAT. One based on ES9039PRO or ES9039Q2M DAC chips and one based on AKM's AK4499EX/AK4191 chips.
Or better, forget the chips and make us an FCPGA DAC, configurable, and take my money 🙂
Have a nice weekend

May I add to that: configurable for HQPlayer.
We diy’ers like to try hardware and software that’s available in de market.
I truly believe that such an approach would open new possibilities and improvements.
I nevertheless are happy with the by Ian offered modules and support; great!!
Hello,
Better have less boards and better support.
Greetings, Eduard
P.s new boards popping up when the old ones are still in stock is weird

You will not benefit from the ian streamer + Denafrips Terminator because that DAC works exclusively asynchronously.
You have a problem described a few posts ago.
But HDMI Pro and Dual Mono DAC can work together without problems.
Thanks. Yes, I'm aware that the T+ reclocks the i2s input and will benefit less than a synchronous DAC. I doubt I will notice a difference from the Sonore, except that the Sonore tends to drop out occasionally which I am hoping Ropieee won't do.
I am hoping that the Ian Canada DAC will sound as good or better than the Denafrips DAC and I can sell it. Either way, Ian's stack is much easier to upgrade as new DAC technology becomes available.
Here's what I'm thinking for my build. I'd like to get feedback on whether this is the best configuration. My configuration is based more on available space than cost. I plan to build a two chassis configuration similar to what @Gabster 2000 built for his youtube series. I'm planning to use RopIeee XL on either a RPi4 (which I currently have) or an RPi3B (if the SQ improvement is worth it?).
StationPi SMT - powered by two LinearPi MkII 5V with two UcConditioner MkIIs for each side of the StationPi.
FifoPiQ7 - UcPure Mk III driving clean side.
HdmiPi Pro - sharing power from FifoPi.
ESS9038Q2M - UcPure Mk III - I'm not clear on whether it is best to use this for all three power inputs, or to use the UcPure from the FifoPi for the J2 (DVCC).
OPA861 - two UcPure Mk III.
MonitorPi OLED - I'm assuming this is required (or at least desired) to set up the DAC? I do plan to have a display connected to the RPi.
I'm going to hold off on fancy clocks until I get everything working.
Anything else I should consider?
Thanks,
Jay
I have both Holo and Denafrips. I prefer Holo R2R. It sounds better and have much bigger room to improve.
Don't understand why Denafrips designs DACs in that way. Even their own DDCs become useless.

@iancanada - I can see pros and cons to both approaches. Reclocking certainly reduces jitter and noise from poor sources, but introduces overflow/underflow problems with synchronous sources. At the very least, I think they should allow i2s input without reclocking.
My Spring3 sounds really great by the I2S over HDMI input from a HdmiPi Pro with SC-Pure upgraded.
But I can not decide which is better comparing with my new ES9038Q2M Dual Mono II using the same SC-Pure and OPA861IV (powered by two UcPure for +/-5V).
They have different sound signature. The R2R has higher sound density and plays more dynamic, while the DM II is more musical and with more details.
I'll post a comparison chart later.

@iancanada - Thanks for your comments Ian. I’m looking forward to comparing your ES9038Q2M and OPA861 to my Terminator Plus. I am planning to use your UcPure mkIII supplies.

You can see the post here which is my current configuration

Hi Ian,
To connect the MonitorPi Pro to the ReceiverPi Pro II I m looking for a longer signal cable.
Any idea where I could find one?
Searching the internet but all are not the correct size.
Thanks in advance.

here are 2 possibilities...

i can understand that with the support...that should be the most important thing...unfortunately you have to be lucky to get an answer in the meantimeHello,

If it is you answer to my question, I meant the 4 pole signal cable with very small connectors. 🙂here are 2 possibilities...

You can cut the control cable in the middle and then extend the wires one by one. Please let me know if you have any questions.Hi Ian,
