I have installed 2 UcConditioner 3V, 1 for the I2S to PCM board and another for the XO board,they are each installed with 8 centimeters of cable up to the load,the XO and I2S to PCM board were previously powered by 2 Maxwell 3000f 2.7 V but with a cable of more or less 30 centimeters,my preference is for the UcConditioner,improvement and evident in the bass and low medium and a slightly more defined midrange,thanks Ian and best wishes for 2021.

Hello Strassbourg,
When you read the French L'audiophile magazines from some decades ago you will know that once you start to use caps with extreme good specs you will have to pay extreme attention to everything in between these caps and the circuit to which they provide their energy.
I remember well how they wrote about cleaning the copper bars and using electrolube.
Greetings,Eduard

Thank you eduard, yes i knew it of course, and i made all of this sense during the implementation of UCconditionner, moreover Ian indicated it in the pdf,

I also read the new review of sound and i also the review of the audiophile, 35 years ago.

Hi Ian, I did complete an order form and sent it to your email address. I want to try the conditionerPI and the LinearPi solo for my HifiBerry DAC+Pro, as an alternative to a ultra low noise PSU I'm using by now (THEL Black-Pulsar BLP 25-09) which already sounds very good, but gets very warm (class A device).

Default Help with ground on lifepo4 causing ripple noise on fifo supply

Just realized that the negative rail from the 12-19v lifepo4 is connected to the stand-offs and since I am using a metal case it connects to the case.
Connecting the FIFO ground and other hats ( negative - pole 3.3v) to the ground connects it to the nasty 19v switching supply and start to get ripple noise on the 3.3v battery supply side see oscilloscope photo

1) should I lift the lifepo4 off the Metal case with plastic standoffs
2) not connect the fifo and hats negative pole to the metal case ground

3) what about the Pi negative is also connecting with ground

I am confused what is the point of isolating all the battery power supplies to connect them all together on their negative poles with nasty noisy equipment.
Any suggestions? What are you guys doing about ground? in a metal case environment.

Thanks for this... Didn't have to dish out for expensive gloves.
