Greetings Justin,

I'd like to pre-order a Pico w/ DAC.

Drop me a line if interested in advance payment.

Gracias,
Sten

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

AHHH! CAN'T WAIT ANY LONGER...

Any idea of when the first amps will be shipped out, Justin?

Well, thanks for putting all those tedious hours for all of our audio enjoyment.

I love graphs! I pulled up a frequency response graph of the Total BitHead (what I almost ended up with before hanging out here enough) and used it as a reference. Eyeballing the graphs, the Total BitHead is about 60-10k ±0.25db whereas the Pico is 30-18k ±0.25db. Now if only my ears and phones were that accurate...
