Is my listeng room too small??

I have an opportunity to put together a simple set up. And I'm sure it'll be a step up from what I have now (NAD, Wharfedale, XLO). It'll consist of a Roksan Kandy K2 integrated with the matching cd player, along with a set of Monitor Audio RX 6's.
However, I'm afraid it may be too much for the listening room I have. The room is 12 1/2' wide, 22 1/2' long, and the roof is 7 1/2' high. I don't sit at the rear of the room as my computer desk is there, so the listening position is about 15' from the front wall. There is only the audio gear, love seat, and pc occupying the space. But the room will soon be treated with a dozen o/c 703 4'x2' panels as well. I listen to all kinds of music, but for the most part, I like Floyd, Def Lepard, Enya, Tom Petty and so on. I really like a full bodied sound, not boomy, but full. I still do need/prefer excellent imaging, big sound stage, instrument separation, instrument placement, and precise vocals.
I know I'm asking a lot, but it's what I'm after.
So, the question at hand. Is my room to small for the K2's and RX's???
And if so, any recommendations given my listening preferences?
