it's often been said that all design is a compromise... and your ahead of the game just realizing that... congradulations on a good first post.... my only comment and there will be others to disagree is that i would not shortchange myself in the monitor dept...if you look around you'll see lotsa people talking about how thier mixes "dont translate"well... and the need to check on multiple monitors... and while checking on different monitors aint exactly a bad idea... the reason it doesnt translate IMO is it was'nt done on good monitors to begin with.... the two most important things you can do to improve your mixes is invest in great monitors and room treatments.... you'll never really know what you got until then....

I would mostly agree with dementedchord. Having reliable monitors and treating your room are priorities. Every decision you make will be based on what you HEAR, so you need to be able to trust what you hear.
