Asynchronous I2S FIFO project, an ultimate weapon to fight the jitter

Clocks are inside the can in your DAC. You can not see what they are until you disassemble the can.
I suggest just keep it as is. I don't think this DAC can be upgraded, even with the same brand DDC.

Ares 12th will be much easier to replace the clocks. Hopefully I get it compared the SQ with my Halo after I upgrade the clock.

Hi Ian,

Thanks for your response, I will see how it further goes.
I will keep watching this site maybe there will be easier solutions for this problem wat I have with the Denafrips Terminator Plus i2s input connection.

Best regards,
Rudy

I see those clock's are on a module, I will ask Alvin if he can send me an new module without the clock's.
So I can use the SC-Pure clock's on my DAC.

Regards,
Rudy

this is interesting - in the terminator plus user manual in the "I2S" section, the configuration does not provide support for the MCLK bus at all... the Holo Spring 3 manual shows that the I2s input "accepts" MCLK... Gustard, Topping - just like Holo...

 

[sernikus]

...and in the terminator there is a BNC input for 45/49 MHz clocks... so Ian's good old MCDualXo + SC-Pure + u.fl to BNC adapter and we could try it...? only Ian knows that...

wanted to let you know that audiophonics is replacing my LIFEPO4 MKIII power supply..and ian had also contacted me.

I think I'll rewrite the user guide pdf and share it here.

Really nice work. Here a DAC….there a DAC, everywhere a FiFo !
Love the table and panels design on your boxes. I build guitars 🎸 too and want to incorporate wood somehow into some of my audio gear.

 

[Aiello]

yes, it is a pleasure to design new cases and to package ian's hardware in a noble way.. Thx

@Aiello,

I want to order a case from you for my new flagship streamer/DDC. Just hope you are not that busy.

Regards,
Ian

 

[Aiello]

@iancanada of course with pleasure, and I will be happy to take the time for you

 

[iancanada]

Thanks Aiello,

I'm working on the StationPi Pro controller. Hopefully I can finish it in three weeks. I'll discuss with you for details after that time.

Regards,
Ian

 

[Aiello]

I'm looking forward to it

Hello everyone!

First sound test.

No sound and no display.

If I put the jumpers on J9 StationPiPro, I think I will get conflict with the clean 3.3v on FifoPiQ7. Will I?

Thank you for your help!

Yves

 

[iancanada]

You need short J9 with jumpers to share the RPi 5V. Otherwise, you have to feed an independent 5V to J5.

 

[Yveskoala]

Thank you Ian!

I have the monitor but still no sound. It displays NO SIG.

I’ll recheck my Roon config (Amanero board is active) and Holo May (ATE2 on i2s).

Any hints?

Yves

@Yveskoala
Please do it step by step and don't mix things up.
I suggest run the software with RPi only, only install MonotorPi to the RPi GPIO. Do not install anything else.
Make sure MonitorPi OLED shows correct music format when you play, then install them to the system.

 

[Yveskoala]

My config has no RPI. It was optional. All I need is to reclock the music from USB to i2s.

How the signal is going from the Amanero board to FifoPiQ7?

 

[iancanada]

Than you need to config the StationPiPro J14, by a jumper short 7-8, to select the USB as the input source.

 

[Yveskoala]

I don’t have the MonitorPiPro, it was not out when I send my order. I have the MonitorPi.

 

[iancanada]

Sorry for the typing mistake, it's StationPiPro J14.

Please download and read the manual and schematic:
