Thank you kindly,
On some hybrid interfaces because of design or what ever,
I suspect bridging,
it doesn't make much difference,
but I was hoping it would on this one as I already own some modestly 
priced USB interfaces but wanted something accessible and flexible that 
would give me the same super low latency I am  used to with my mackie 
onyx board.
There's just no need to run that thing for small projects, it get's 
warm  in that control room even with air conditioning,
and that's just one less large heat immiting electronic item I need to 
run when I don't need to.
