DIY portable audio recorder

I want to build a portable, robust SD audio recorder with two channels, 24 bit sample width, 96 kHz sampling frequency, phantom power and sturdy XLR connectors and pots. And high audio quality, of course.

As I am not an experienced programmer I thought of using an embedded linux board like the BeagleBoard, a 24/96 codec and a (touch)screen or the circuit of a portable sound recorder like the ZOOM H1 as a basis.

Any suggestions, ideas, comments?

I realize this is late, but any developments? I'm having the same itching desire: design a modular low cost high quality recorder around the BeagleBoard Programmable Real-time Units (PRUs), for now I nicknamed it the flosscorder and only have collected some links here: https://pinboard.in/u:lutzray/t:flosscorder/

the module should be interchangeable and would correspond to each particular use case

preamp module (anyone has his preferred opamp, 48V? lav power?)
ADC module (24 bits? 32 float? your choice)
interface module (oled screen, e-ink? no visual interface, just two buttons: REC & STOP?)
power module (wall? portable? USB bank?)
