[linux-audio-user] Focusrite Saffire LE vs. Presonus Firebox

[Mathias Friman]

Hi list.

I'm looking to buy some firewire sound card, and I have got a very good price on a
Focusrite Saffire LE, but it says on the Freebob website about the Saffire:
"FireWire Interface with DSP - DSP and mixer not supported by FreeBob". What does
this mean practically? On Focusrite's website it says about the LE: "Although only 
the original Saffire has onboard DSP.." which should mean that the LE has not.

Which are the pros and cons compared to the Presonus Firebox which I can obtain for
a marginally higher price? Is the Focusrite Saffire LE even fully workable under Linux?
If "mixer" means the included control software for Windows, what possibilities for 
controlling the device exists?

And is the support for the Firebox sufficient, or should I go for something completely 
different in the same or even lower pricerange?

I'm thinking of even buying a Presonus Firepod if I can get it at a good price, is this
something that is 100% supported, or are there still things that need to be fixed?

Regards,
Mathias
