You would be more likely to get help with your problem by asking on the Volumio Forum.

Maybe a litte bit off topic...... 😇
Engineers often run on coffee.

That's my business.....
I import coffee from a very small French coffee roaster. A family business since 1921. The very best you can get.
I hear you thinking......French⁉️ Wine come from France, but coffee?
I'll tell you a secret....Espresso and the Espresso machine are developed in ...France in 1866

have a look at Home Koffie en Chocolade - Cafes-Canton.nl

Regards,
Frank

Default 3000F Maxwell ultracapacitors

The monster Maxwell 3000F ultracapacitors arrived yesterday. They are really really bigger than I thought. Looks a bit crazy. But the good thing is that they are not heavy.

It's supposed to be the best power supply in the world due to the 0.29 mOhms output impedance and 210A (RMS) continues output current.

For now, I'm just curious how good they are by comparing with the 350F ultracapacitors as my ESS DAC HAT power supply.

If I'm happy with the result, I'll open a new thread to discuss developing the big high power isolated ultracapacitor power supply, maybe +3.3V,+5V and +(-) 15V. But to my opinion they are too big for RPi audio applications.

In this thread, I'll keep focus on ESS DAC HATs, corresponding I/V stages, ESS controller and RPi ultracapacitor power supply solutions.

Pursuing sound quality will always be unlimited

Ian you are goregeus. Mines are on their way They are not to big! If they are the best in terms of sound then who cares about the size anyway ...

OMFG they are huuuuuge, I love it. My wife would never stand for it but I love the absurdity of it all. ;D
Now, if practical considerations matter, the smaller brethren are probably preferable for a RPi solution.
Personally I always consider true audibility and diminishing returns. If I canít tell a difference between big expensive gear and smaller cheaper dittos, Iíll go for small and cheap every time. OTOH if there is a clear difference, it becomes a much tougher decision.

P.S. After digesting the initial shock... if using a regular ďfull sizeĒ cabinet there is usually a lot of air inside, maybe this could be a good way of filling some of that air?

Watching with great interest... Size isn't an issue for me either. Currently I am using 4x linear supplies (thanks GStew), one for each board in my Pi stack, and those dwarf the Pi as well.

Mark, I have the same idea as you--eventually I will case everything up when I find the sound I am after.

3000F ?! Isn't this necessary? Pi or the clock board isn't a very power-consuming device.
