Hi all, just my report.
I ended up buying the USBPre2.
It works great under Linux, but since ALSA does not have USB2.0
support yet, I can only use 48k sample rate.
The sound that comes out of the device is really good quality.
Pros:
+ I can't even start comparing with the SaffirePro, it is REALLY MUCH BETTER,
no doubt. One second of testing is enough.
+ I don't know what could be more important then support and sound
quality, but it has
a good number of out/input options.
Cons:
+ ALSA could offer better support for USB2.0, even though it works
great under 48k.
(but it's more an ALSA feature request)
+ it's a bit expensive. I don't know if the price is fair, but maybe
it is. Maybe they just
use good quality parts and assembly in US instead of China. I don't know.
