Hi Brent,

when listening to 44.1 KHz, 16 bit wav (weather with you, crowded
house) by its headphones out, I noticed that at least the headphone amp
of the PreSonus isn't that good, as the one of my RME audio card.

At next I'll test...

...just playing fluid DSSI and hexter DSSI, 18 individual outputs at
the same time (8 anlog + 8 ADAT + 2 SPDIF). I don't have a reference at
the moment, as long as the sound quality shouldn't be really bad, I
can't notice sound issues, with the gear available at the moment. It
might be, that even the UB2442FX-Pro doesn't work. If so, I need to ask
a friend to use his Mackie, but the Mackie also isn't good.

Ralf
