As promised, here are some measurements of the final version of the Pico. I know measurements are given very little consideration, so I'd like to explain that to me, these are not taken as measurements of how something sounds, but measurements of the amount of work put into a design. I wanted to make sure every chip was as close to its best performance as possible. It takes a lot of incredibly boring work to track down and remove each and every noise spike and find what conditions make each chip happy for best performance
Noise floor is at or below the baseline of what I can measure
