Can't wait for your other experiments! As requested, here's what you PM-ed to me:

 

Hi, lps is very expensive. 

It is possible that the inner noise of the tp link (all component noise) would be much higher than the output noise of the lps1

I am going to go further in noise reduction tests with the tp link and it would be usefull for you before you spend a lot of money.

1) i am going to replace the 200uV noise existing LDO with a 4uV noise LDO to see if it has an impact.

2) i will do a supply test with a 3,3v lifepo4 battery that the lowest noisy supply that can be.

3) i will see if i can remove the green light diods

 

I could tell you if it worth or not to use a low noise expensive supply.

 

I will depend too on your player and usb card. If they are badly supplied, it will ruin the tp link upgrade.
