Make / Model: Focusrite Saffire Pro 40
The Focusrite Saffire line of interfaces runs across Fireweire, instead of the USB of the later Scarlett range. The Saffire also has different mic preamps, that are different than the Scarlett. The Saffire preamps have more headroom, but sound a little duller. However, they seem to be higher quality overall.
The Saffire Pro 40 and Pro 20 tend to feel much more solidly constructed than the Scarlett devices, and seem to be aimed more towards working studios, than individual musicians. Accordingly, the Saffire mix software offers features more conducive to studios than the very simplisitic device software of the Scarlett.
