Hi all,
This is my first post on DIYAudio.
I have a limited understanding of circuits and electronics, but have good experience with Hifi, terminations, soldering, commercial pro sound standards, etc.
I apologise if this question/answer is silly or obvious.
I was hoping to seek some advice to help explain how this kit:
IAN CANADA CONDITIONERPI Ultra Capacitor Conditioner Board for Raspberry Pi - Audiophonics
.....would differ (performance wise) from simply inserting a few 5vdc super capacitors in parallel with my RPI power supply.
I have struggled to find much feedback on this item, and would appreciate your time and insight.
Manual:
https://www.audiophonics.fr/en/index.php?controller=attachment&id_attachment=1363
My goal is to further improve on my RPI4 power supply, which is currently the iFi power x. This supply provided an excellent improvement over the standard RPI SMPS. iPower X by iFi audio | New Ultra-Low Noise AC/DC Power Supply with International Travel Adapters
According to the product specifications the PS has a 1uV noise floor, which is consistent with previous model testing.

Thanks

It shouldn't make a difference if your digital/analog hygiene is good. If you're just taking digital audio off the RPi HDMI output (with proper buffered clock recovery ala WM8804), it shouldn't do anything noticeable.
If you're trying to do analog in the same box the RPi is in with the 5V supply, then it might make a difference.

Thanks for the reply, much appreciated.
My setup is:
RPI4 USB audio to a RME ADI 2 dac.
IMO and experience, I noticed a difference with the iFi power x V's the standard 2.5a 5vdc SMPS. I don't have a problematic environment.
My question is really centred around how the IC kit would differ from inserting super capacitors in parallel with the power supply.

Performance would be the same. But ultra capacitors can not be used safely directly. You need a full set of management. Charging, discharging, on/off control, input detection, output control, balancing and protection....
It could be very dangerous without management. It equals to short if it is empty and can delivery up to hundreds of ampere current when it's full...

You can try UcConditioner if you use external power supply.

Thanks Ian,
Makes sense. I appreciate your response.
I think the PI conditioner best suits my setup, and needs.
With France now in lockdown, I wonder if these will actually leave the country atm?!

I'm sure its operating in spec, and works just fine (better than most).
Linear power and improved power supplies have been used for PC audio for many years. I ''feel'' its generally accepted that power improvements can help digital audio.
Maybe my bias's are manifesting differences that aren't there.
To be honest I don't really care.

I found that with a high input impedance amplifiers (240kohms), galvanic isolation between the USB audio card, and the PC/laptop/digital transport (audio streamer)... is a must.
Thanks Ian, the devices product manual suggests a considerable improvement to sound. Is this statement related to digital USB and analog HAT applications?
My application is USB out to an RME ADI 2 DAC, which apparently has an excellent USB implementation and jitter rejection.
I already utilise an ifi Power X supply.
Extract from your manual:
For audiophiles, upgrading Raspberry Pi based audio application with ConditionerPi could be a one of the most
efficient solution to achieve better sound quality right away."
My understanding is that the conditioner pi would be most beneficial when using a HAT dac on the same raspberry pi.
But I would be also interested in @iancanada answer to the above question posted by @grizaudio, since also for me the prevalent use is USB out, in my case to a Khadas Tone Borad.

ConditionerPi can improve your simple DAC HAT right away even you just use a USB power adapter.

Dear Ian Canada,
I have an audiocreative 1794 dddac dac which must be powered at 12 v 1.5 / 2 A. Right now I am using lifepo 4 batteries, but I would like to know if you also have supercapacitor power supply boards in production for the specifications described.
Thanks, regards, alessandro

Should I interpret this response to mean, the conditioner would make no difference in a USB to DAC scenario?
Hello Fella's
I have a question regarding the Conditionerpi. We all know how by removing the micro usb power cable from the Raspberry Pi can potentially corrupt the SD card, and I know because it has happened to me a few times in the past.
My question is by shutting down the Raspi by the conditionerpi's S1 on/off switch, would that be considered as being a "safe shutdown" procedure with no worries about SD card corruption?

Dear IAN, thank you for your sublime projects. I have a question for this Power filter board.
Can it be installed with switching power supplies?
These excessive capacities do not risk to compromising the feedback circuit of the switching power supply?
Thanks in advance.

I reread this discussion and I noticed that the power supply used by Griz is a SM type. Not having been denied the use of an SM, I imagine that this Conditioner can be used without problems on switching power supplies. My doubt, however, remains because reading other conversations (also on this forum) it is always not recommended to add capacity on SMPS if not properly calculated. Obviously this speech differs from the original article in question, but in case my question was sense, it would be interesting to understand how the Conditioner works to overcome the problem.
Dear Ian,
I understand you are very busy, but why is it so difficult to get an answer from you? Probably my questions are too complex or just too stupid. It seems that in the products for sale section your responses are more active. In theory this forum would also be for sharing knowledge not just selling. Anyway, If I can give you some advice, it's not enough to make good products, customer care is also very important. Greetings
