Hi,

Disclaimer:  Never used one, so I don't know how it performs or how
easy it is to set up.

I'm using one right now... :-)  Theyre good, I've had some little trouble getting ffado to work back in the day,
but now Ubuntu Studio, Pure:Dyne, AVLinux etc all get it right first time.

Do yourself a favour, and dont upgrade the Echo Audiofire's to version 5.* of firmware though...
I've noticed a decreased preformance since. Kinda hard to "backwards" flash them too... They do still work
for me though.

As Sean said, I like Echo stuff too..
Good luck, -Harry
