I am using available components, running on the worlds ultimate power supply, Ultracapacitors .
I am not affiliated, sponsored or receive any incentive from anyone.
This Build would not be possible without Ian Canada's great inventions and dedication to the DIY audio community.

That's a lot of effort for an RPi based system. I went down the Allo rabbit hole with pretty good success at one point. I expect this will be a nice DAC when it is all done.
I have a few thoughts.
Get rid of the screw terminals - you are undoing all your hard work using them. At the very least, crimp ferrule ends on the wire (they are round tubes that use a special crimp on all sides). Copper wire will always oxidize when exposed to air, and the screw terminals do not put enough pressure to make an airtight seal. Screw terminals will also come loose due to thermal cycling. Hopefully you did not tin the wires before you put them in the terminals - this is the worst thing you can do. I like to use solid wire for power directly soldered to the PCB, and gold plated headers for signal wires - soldering stranded cable is almost always a terrible idea.
On the power supply, consider routing the mains and low voltage as far apart as possible. I also suggest twisting each input and out put pair together. You have done a nice job keeping the power supply as whole from radiating into the environment, but nothing to isolate the output cables from the rest of the power supply.
Thank you for the great video, I have started my own project after watching your build. Ian is getting more business😂 and please keep up the great work.
Very insightful video! You made
My day
Great work I would definitely like to build one in my future. Thanks for all your sharing.
Thank you Roger, good luck and have fun building
Thanks Gabster , I Appricate all your hard work and dedication . I wonder how hard it would be to build a cd transport I know most people stream these days but i am they very few who love spinning the silver disk 😆
Thank you Tee-Jay I have been enjoying your video a lot
Building a great transport requires some accurate micro mechanics I doubt you can make one from scratch best is to buy just a transport and focus on building a great Dac for it
Capacitors hold a fraction of what a battery can provide even super capacitors and with 60c rated lithium cells available that can do 300 to 400 amps of power per cell it's a mo brainer that they should be #1 choice or at least battery+capacitors but just capacitors makes little to no since
Hi Gabby, your work is awesome! I see you often using a noise detector to show how much noise is there in components, can you share which one detector you’re using?
Thank you
I did a video just on that probe here is the link hope that helps

Gabby, thanks for all the effort. How is the power supply video coming?
it's cooking :)
Congratulations, Gabby. It looks amazing so far. I’m keen to understand how you are connecting the output transformers to the DAC board. Are you running connectors from the DAC board GPIO pins to the GPIO on the transformer? Was not so obvious on the video. Looking forward to the next one!
Thank you Philip
The dual mono Dac board has a 8 pin connector like a mini GPIO and Ivan Transformers has connector that goes in it but in my case I had to do a small custom extension as I have a metal case cover in between them.
I will try to show it in the future Dac video after the power supply one.
That is one fully jammed PSU case :) But nevertheless a very nice built and I appreciate the video! I have one kinda off-topic question, where did you get that noise sniffer?
Amazon Check the description of my Video about it

It would be hard to build anything similar since you can't find half the boards.
Hi Gabi, I recently discovered your channel and glad I did. I enjoy your content. Can you make a video on stand alone supercapacitors as a power source for my Denadrips DAC and preamp. Have used batteries and u r correct not the end solution
In Part 1 I talk a bit about it at 5:00
But can do a video sometime about just that
Which Denafrips Dac do you have connected to batteries and what voltages do they need I never tried on mine yet but very interested
@@Gabster1 sorry I meant my pre-amp. Its a Korg Triode B1. My Denadrips is the Area II. With open baffle speakers. Again really enjoy your content.
Hi, I just clicked to view part 1 and it is not available.Any ideas? Thank you for the video.
Great video and project. How does one know how this all fits together? I reviewed the Ian Canada github site but there aren't any instructions. I would very much like to build one.
Thanks Andrew I felt the same way a couple years ago when I wanted to build something there is a lot of info in the pdf of each components but hardly anything on how to put things together that is why I started this Chanel
I would start with a simple design on a wood plank first.
Ian Canada has a couple Videos on his Chanel Look for them but I wish he would put out 20 more Videos also The DIY Audio community can help but no start to finish info.
There is so much effort, time and money to make this build. But how it sounds being compared with the terminator for example? Does it worth it? Anyway thanks for sharing.
BTW there are plastic battery holders for 66160 batteries which allows to make these UC packs more stable and convinient to fix.
Thank you, check my latest video airing tomorrow towards the end I talk on how it compares to the Terminator. :)
Thank you, very nice project! Where could I get such a "noise sniffer"? Maybe you could share the maker / model? Seems quite a helpful tool. Thank you very much
I am making a video about it soon 😊
@@Gabster1 thank you! 😊
Hi Gabby, could you share the name of the noise sniffer and where you got it? Thanks keep up the good work!
Hi Peter it is actually a cable tracer a ver crude tester but what I like about it is the simplicity and it is sensitive to the audible frequency
Mine was given to me but it is similar to this one and they are cheap

Hello, I am trying to build a similar DAC. Got the parts from Ian and build my first UCPure with Ultracaps 2.7V / 3000F. The Voltage is fluctuation between 3.02 and 3.34V with the blue pure LED on.
I think this should be rock solid 3.3V?
Thank you
Lithium is superior to capacitors
After looking into a lot of these components they seem like snake oil, powering the PI with Lithium ion batteries is easier and far cheaper than ultra capacitors and provides a better more reliable supply. To be fare in the digital domain you really don't need to worry too much about high frequency switching noise as long as it isn't so bad it causes errors on the I2S signals coming from the PIs GPIO header so just using a cheap power brick would also be just fine. The only thing you really need to worry about is shielding the DAC and having a noise free supply to it together with a high quality reference voltage. The best results would be to convert I2S from the PI directly to optical SPDIF and have that going onto a dac that is well shielded with a good lithium ion battery power supply, everything else in this build really provides no value.
Hi, very nice.
What are the specs of the transformers?
link in the description :)
I am surprised you did not decide to use a battery power supply! Is that not the best power supply one can choose?
Ultra Capacitors are the best. Batteries are second best.
Batteries are severely limited in discharge rate and have a fairly high output impedance.
Batteries almost always suffer greatly if they have to respond to dynamic loads.
Prolly almost fine for a DAC, not so good for a preamp, and terrible for a power amp
@@joshua43214 Could you back up what you say with some numbers?
@@zaldam Basically using ultra capacitors like this is a waste of money, batteries with linear regulators fronted by small ultra capacitors to deal with load spikes will provide perfectly smooth power and also lithium ion batteries can hold orders of magnitude more energy. Thing is they don't cost much so the audiophile types consider them inferior. Half of the components used in this build are totally pointless because they are dealing with noise or jitter on digital signals where it doesn't make any difference as long as it's within logic thresholds and timing specifications.
How much it cost for you?
Thank you for content!
budget for $3000
Gangster, where are the sound clips? We can tell a lot from clips on CZcams, believe it or not.
