hi all. i'm currently using an M-Audio ProFire 2626 for all my recordings that require more than 2 simultaneous inputs... it does the job, and sounds acceptable to my ears.
what i'm wondering is how much of a difference is there in terms of sound quality, stability and other things between a consumer interface (M-Audio ProFire 2626) and a higher-end "prosumer" model (perhaps and RME Fireface 800).
I will be expanding my array of studio gear in the near future, and want to know how these more expensive interfaces make up for the steeper price - is it just the preamps? the software?
i want my future purchases to be long term, and i would like to invest in gear that will be at home in a professional studio...
...some guidance would be great
