I have a Q10 and I like it a lot. I am a college student - but I live with my parents therefore I have the space that I need, and the money that I need to buy some gear.
If I had it to do again - I would buy a Delta 1010. Probably will buy one (or its follower) around christmas.
I will certainly keep the Q10 though. Problem with the Q10 is you can never *really* disable the onboard pres to the best of my knowledge. You can run in from another pre...but the Aardvark pres will still affect the sound.
The Aardvark pres/phantom power/software is good though. in terms of drivers, they are *finally* getting their act together. It took them a while to get around to 2k/XP (they are one in the same..to vark)...but, it's finally getting there. Some XP boxes are up and running with no prob. (But 2k is much better for an audio system anyways

)
Aardvark is a good choice for you...if you really don't think you need 8 ins, you can get 4 with the same pres on the Aark 24/96 thingy save a couple hundred bucks. I think all of the featues of the Q10 are worth it though. At this point I just want a variety of preamps..
want a grace, want an rnmp, want the SP, want a vintech....so, when i get those, i will be getting something like the Delta.
I support the Q10 for you though, later.
