dt990pro

Hey All,

I wrote and recorded the attached track over the last week. Before going live with it, I'm wondering what people think here. Do the lead guitar parts sit ok? I'm worried I've mixed a few of them too loudly..

is there a difference in the sound of the k240df and k240s?
I want to buy mixing headphones, somebody i know who run a good studio for years suggested me beyer dt990pro, but they are a bit over my budget, how do they sound different than the k240 ? do they really worth saving up?

thanks!
