Cheers Montydj, that's really great feedback, and everything you've said makes alot of sense, I've just switched from Absolute 2's to KRK KRoks and the bass on the KRK's are totally different, the detail is there but I'm used to the boominess of the Spirits to judge my bass.

I tried backin off the low regions of the bass a bit and yeah I got loads more kik, and with a few tweeks on the kik got everything sitting ok, although now I'm not sure but I think the kik might be a bit prominent. There's also a subtle cut in the bass region over the whole track to reduce muddiness low down, but I'd really appreciate it if you'd run it through you're bass lab again to see if it's still too bassy, coz if it is it's the kik I'd say, coz there's no bass notes where the kik sits anyways, so the sub problem may well be the kik.
