Thanks to Shannon for making such a great kit. I love the sound of the Budgie with my cheapie bookshelf speakers. And thanks to all who gave advice when my troubleshooting was stalled.
Here are some pics of the completed project:

Quick followup question, would it be possible to figure out the power output to the headphone jack with the unmodified 20/20 circuit? Say at 70 Ohms? Sorry for the rudimentary question but I couldn't find any existing information on this subject.
Thanks again for designing such a great amp!

What's interesting is that Audeze recommends an amp with at least 1W of power to the headphone-jack, but the Budgie seems to perform just fine.

Good info - thank you! Seems like a perfect range. The 1W to 3W range Audeze specs basically means some lower powered portable devices may let you down. I think they worry about voltage swing capability more than power sinking. Tube amps are a perfect match for these planar magnetic headphones (and headphones in general) as voltage swing is no problem. 5V USB powered devices won't have the same headroom.
