great, great product!

i bought this system with the PCI-E card and the unit sounds great with top notch converters, routing and build quality. I have heard a lot about RME and their quality - this product is a great example of wonderful RME quality. If you are looking for a sample of what this unit can do, refer to the live Kraftwerk album which was recorded with 4 Multiface 2 units through the laptop bus cards. Amazing sound!

A hidden advantage

The box 'just works' and it is an excellent mid-range product - more to the upper end of it (WC, ADAT, balanced analog I/O. MIDI...)
There are more expensive interface that are actually better. But there is one powerful feature about the Multiface that very few people are aware of: There's an excellent Linux driver available for this interface. With the proper audio distribution (AVLinux, puredyne that I am sure of) drivers are part of the default installation so the Multiface works under Linux 'out of the box' - using the PCIe card as in my case.
I find that close to fabulous...
