anyone using the RME ?



Hi folks.
Does anyone use the RME multiface and the RME digiface ? How does it sound? Did you compare it with other interfaces? I am planning to upgrade to 24/96 and I need to choose between the 1296, the 896, the RME and the Delta 1010. Please give me some feedback! What do you think? Wich one sounds best in your opinion?
I use a Pentium III PC with Logic. Is there any compatibility issue? Thanks!
