Already got TWO G70's, so pretty obvious what I would do! Still waiting for something better... And my back is still fine, thanks, Ian!

PA? I kinda like those QSC self powered 10" K10's with a sub. Smooth, small and LOUD!

Studio... a lot harder choices. Still use my K2500S for many projects along with the G70 and a bunch of VSTi.

You know... I haven't really bought anything new in a while, other than a BK-7m (to act more as a sound source for my KX-5 than as any serious arranger needs), despite so much being out. I guess there comes a point where your gear outstrips your needs. I think I passed that after getting the G70!

Maybe I'll just stick with what I know... headphone
