Raspberry pi 4b ultra low noise Power Supply

Congrats on all your achievements.

Often, comments are not intended as racist but are perceived that way by some people. In that case, I think it’s best to be sensitive to the perceptions and change or delete the comment.

In the USA, many of us are ultra-sensitive to this issue in view of recent events.

I would like to understand how these comments

could possibly be construed to be ‘racist’…

That makes sense, and at the same time shows how moderation can induce confusion and misunderstanding…

He replies to the apparent comments. If you click on my name linked to his comments it shows what I said that was construed as racist. Nothing has been edited or removed. What you see is what caused offence. I say this not to defend myself but to make sure people know what was said. I don’t want people to think that I must have said nasty stuff then simply edited it. I would also ask that mods make no edits either.

cheers, man for taking the time :slight_smile:

Henry, I welcomed your post and that anyone should conclude there was a racist aspect to it is beyond me. Perhaps a sign of the times but not good for the future human race.

PS, I re-read the thread as my Shanti is playing up on the RPi4b.

Can we get back to power supplies for the RPI4b? I am about to buy one and have a vested interest in the outcome of this discussion.

Would an ifi ipower be a good supply for the rpi4b? I really cant afford a 300 dollar power supply, so trying to get the best sound for a reasonable cost. I value your input.

… so, if you don’t hear any undue unmusical noises from that RPi setup, and especially when not using it with a DAC HAT, save the money, don’t let fear, uncertainty and doubt take over, but just enjoy the music!

If you are using USB or a digital HAT from your Pi, I very much doubt you will hear any difference with a linear power supply. I certainly don’t. If you have an analog HAT, it might be arguably possible to hear a difference, but I doubt that too. The PI (and HATs) have on board regulation, to ensure the correct voltages for the circuitry, meaning a wide range of input voltage (and some ripple/noise) is acceptable. My opinion: save your money.

Hi and thanks for the reply. I’m not using a hat, but going from the usb 2.0 on the Pi to the usb 2.0 on my dac.

Normally I would agree.
But I’d with one RPi4 and the official RPi power supply hissing, while connected to the Penning USB DAC in my AudioValve Luminare.
After switching to the Shanti power supply solved this issue.

But I would here also try at first the standard power supply and if it’s working without problems, then all is fine.
