Hi. Ok Clos. Here is the best advice I can give you at this point. Consider this. When you record, you are monitoring in headphones, no? You can hear what you are recording directly. But, when you mix, since you are mixing in headphones, you have no way of knowing what your mix sounds like in the room until you play it back in monitors. But it's too late then. You've already made various sonic judgements based on what you hear in headphones...which is not the same as you are not hearing reflections, comb-filtering, width of stereo field, etc. And that's the problem. Once you've made these decisions on headphones, you can't revise them. That is...unless you do a total remix..which..will give you the same results if you are using headphones, as they are not telling you the truth.
You see..the whole point of monitoring a mix, is TRANSLATION. Which is how well your mix translates to other systems and rooms. For YOU, that probably isn't a problem, as you probably only playback in the same room as recorded, and over time, you learn how your headphone mix translates to that scenario only. But playback your recordings in other rooms, cars and systems..and you will see what I mean.
What most people strive for in a mixing environment, is haveing a setup/room, that does not lie to them. They can trust that thier sonic judgements will translate to other rooms and systems fairly well. Usually, most people find out that because their room DOES lie to them, when they playback in other systems and rooms..there is usually a way over the top use of EQ in the low frequencies...because they can't hear it truthfully in their mix environment. And this is due to small room modal response and boundary interference(destructive reflections) masking what the monitors are telling you. Hence, all the talk here regarding bass trapping. Yes, it is important, as this one single aspect of a CR can make the difference in how well your recordings translate. However..this is why I asked what your intent is with your recordings. If no one else hears them in any other place than your room...well, only you can decide whether or not they are good enough for that context. However...at which time you do have a need for your recordings to translate..you will see. So that is my best advice. Try playing back your recordings in as many other rooms/systems/cars, and see what I am telling you. That is the only way you learn.
At which time you DO decide you want to improve your CR monitoring environment..well, give us a holla and we'll try to help you
Till then...good luck and have fun.
