Hi. Øivind.
From what I've read, the latency isn't great. Might be better on Mac??
The converters and preamps are very nice, though. (I know Frank at
Matrix Pro Audio (who also told me)).
From personal experience, I would definitely go for RME (BabyFace, perhaps)
Great drivers, low latency, extremely powerful internal mixer (TotalMix) and very good product support.
They support / make drivers for old products, 10 years old +.
All the best.
