ok fick svar från focusrite idag....
Hi ,
yes, the same pre on both units. The LE has 4 inputs vs the original Saffire's 2, but the original Saffire has 8 outputs vs the LE's 6.
Saffire has DSP, LE does not as you note.
Saffire has dim and mute switches on the front panel, none on LE, also has better LED metering on the front panel and two headphone buses/sockets instead of one.
Saffire front panel is white livery, Saffire LE is black. Saffire software is laid out a little differently (also coloured white vs LE's black GUI) and has a few extra options (mostly DSP related.)
Otherwise they are pretty similar- same plug-ins etc (though Saffire can run from its own DSP of course as well as natively as VST/AU.)
Hope this covers all you need to know.
All the best,
