[recall]

One thing I will say is that before you start chasing a perfect mix select a commercially available cd/song you are very familiar with. Spend a couple of hours listening critically to that song and make notes - vocal level, overall tonality, how bright the cymbals are, how loud the kick/bass is etc etc.

I would do this on most if not all the systems you are listening on, it could be that the issues you are finding with YOUR mix may be present when listening to commercial recordings as well. In other words they are inherent in your playback systems.

If nothing else doing this is an eye opener and can teach a lot about critical listening.

Of course this is no substitute for a well treated room and mixing across a few sets of monitors but it may go a long way to understand what translates well and where the strengths and weaknesses are with your playback systems.

Good luck, we have all been on this road!
