I've created this Google Docs spreadsheet to capture the specs of all DAC-amp dongles that

• are USB-powered,
• provide at least 60mW per channel of unbalanced (3.5, single-ended) output at 32 ohms, and
• have physical controls.

I know I'm not alone in favoring physical controls, and I hope this spreadsheet will be a useful starting point for other Head-Fi members who favor--or, like me, insist on--physical controls in their audio dongles.

The thing is, I'm a working man, and I'm up in years. I don't have the time or energy to complete the details and maintain the list as new offerings emerge.

Can I interest two or three of you in helping me maintain the list? If so, I'll send you a link giving you full editing rights when you open the document from your Google account. You can even add columns and edit my wording.
The rest of you are free to save my spreadsheet, upload it your own accounts, and adapt it as you see fit.
