RME Fireface 400 by Spec
Overall a solid card for its time. Most criticisms of the card are centred on the pres and the DAC. for an ITB box guy like me the pres not an issue and could easily add external DAC.
The strength of the card - and all the RME gear - are the drivers, driver support and the awesome total mixer software. Also the FF 400 is has ane xcellent build quality: built like a tank"
Had the card since 2008 and never had a problem
