You should still proof the list to make sure it is correct. Quantities are the higher of necessary or minimum order number

I count 12 on this page alone; surely someone has soldered one up

I’m interested in results to gauge what to expect somewhat from the one I got on my upcoming DAC

My stuff arrived (I got a USB DAC kit too). Both of these are a lot smaller than I expected. They should be fun to build. I won't be able to start for a few weeks though.

Arrived in Zurich today with a USB DAC kit also. Thanks for all the hard work Gus. Just happy there is professional smd soldering station with a microscope at work. Those DAC IC's are tiny.

For guzzler and any others who are currently building I'll post a pic of all SMD parts for the board that guzzler shipped, + dac + regulator. I have the inverters, however because I will run the signal directly into an ISO150 i won't use it.

Despite how it looks it appears as though it will work. The method to get the IC on in the absense of any soldering flux was to simply gob the legs full of solder, then use a desoldering braid over all the legs, that left that brown stuff. But no solder bridges remain (except the ones that need to be).

Here's my effort:

/EDIT: SMDs were done using a 13watt pencil. Guzzler the heat relief connections on the bottom 2 caps were way too large for my liking. The iron did not like working with that at all, and it was very hard to make the soldier stick to the pad.
