I have a LynxOne and it seems to work very well with Giga. Sometimes when using Giga with Cubase on the same machine, I notice the latency will increase after a while, (it happens with my Diamond Monster card too.) I restart and everything is fine.
That may be a quirk in my setup. The Lynx card sounds wonderful, and it has selectable +4 or -10 dbv outs. It\'s very clean and it\'s nice and loud.
