That's very good advice Jason. I will have to consider that when doing work for clients etc. So far it hasn't been a really huge issue but then again, without actually having all the acoustic treatment, it's only speculation at the moment as to how much it is hurting/helping my mixes. I tell you that one thing that would really help me get better mixes is mastering MIR a bit more. Due to the room sizes that it has at the moment it tends to have much larger reverb sound than what I am looking for I think. I think I need to consider picking up the roompack 2 for the smaller reverb rooms to help dry up the whole mix a little bit "naturally".
I find the whole idea of how all manufacturers of studio monitors claim they have "flat response", blah blah blah. Yet, every one of them sounds absolutely and completely different. How can they all be flat, and yet be so absolutely night and day. Some harsh, some laid back, some bassy, etc. It's almost comical with their claims and yet no spectrum analyzer shows them to be "flat". Sure the D/A convertor can affect this but when you use the same Lavry D/A (which is no slouch) on all the different brands and yield absolutely different results is quite comical. I guess at some point no matter what you do, you just have to learn to adjust based on the tools you have and learn what faults your mixes will have due to your equipment.
