What computer interface are you guys using with your pro monitors? I have Rokit 6 , Rokit 10S subwoofer. I would also like to use it as a headphone amp for my 650's.

I been the quad for about a year or so now, previously I was using fiio e7/e9.  
With hindsight I regret not getting the octa version but hey I can always give in to temptation in the future.

you think I be making a mistake with a less expensive Focusrite Scarlet 2i2?

I dont honestly have any experience with the focusrite range, I would do some research on more recording based sites.

Gearslutz might be a good place for finding that out: http://www.gearslutz.com/board/forums/

I've got a Focusrite Saffire Pro 24 and it's got a great balanced output for monitors with a dedicated volume knob, it also has a solid headphone output that works very well with my HD650s.
 
I also have a Motu Ultralite MK3 which has pretty much the same sound quality but has more options on how to program it. The headphone output is good but would definitely struggle with hard to drive phones like HE-500s.
