Sure thing, man.
Right here.
But the simple answer is: The Q has most of the bass of the PRO900; it's more articulated and less robust (the digiZoid ZO improves this situation greatly, adding robustness without sacrificing the low frequency detail retrieval of the Q). The Q does not, however, have even remotely the high frequency extension that the PRO900 does. It's pretty good, but the bottom line is that they're stage monitors. That means they're easier to listen to than the PRO900, but nowhere near as exciting. I go into more detail in my review above.
From what I understand, the TF10 might fit what you're looking for. I would try them out first, since you can actually return them to amazon or wherever if you don't like'em. If you do like them, you can always have 1964 reshell them for you...they do an FR graph before and after the reshelling to ensure they don't change the tonal quality of the IEMs. And if you don't...well, just send them bitches back and buy the Q afterwards.
