It's that question again, and it's here for you to answer and gain cookie points!

Here's my array of the chosen ones:

ECHO AudioFire 4  [[ http://www.echoaudio.com/Products/FireWire/AudioFire4/index.php ]]

Edirol FA-66  [[ http://www.rolandus.com/products/productdetails.aspx?ObjectId=731&ParentId=114 ]]

ESI QuataFire 610  [[ http://www.esi-audio.com/products/quatafire610/ ]]

Focusrite Saffire  [[ http://www.focusrite.com/products/saffire/saffire/ ]]

That was narrowed down from   [[ http://ffado.org/?q=devicesupport%2Flist&filter0=&filter1=&op2=OR&filter2%5B%5D=perfect ]].

All these satisfy my need for mobility and at least 2 DI and MIC inputs. From what I know, they pretty much cost about the same, or within 100-200 bucks apart.

* All except the Focusrite are hybrid inputs, so it has the upper hand there.

* Only the Focusrite has onboard DSP effects, BUT unsupported on Linux (ffado)

* Only the ESI officially mentions support for Linux

So here's the homework for you guys:

Reorder the list in decreasing order of merit. Conditions include (in order of decreasing importance):

* Preamp Quality

* Linux Support Extent

* Beauty

* Portability

If that one's too tough, then just pick 1 (or 2/3 depending on which of those you have firsthand experience with) =p 

Thanks and good luck!
