Ideally an in room consultation would be best but for the vast majority of people on this forum and in general that is not really an option. If you are located outside a major city, it is all but impossible to find an acoustic engineer that will perform an on-site analysis for anything approaching a reasonable amount of money. I am located in Canada and I couldn't even find a single acoustician listed as operating in Canada. I am sure that there are some companies that are providing this service in Toronto, Montreal and Vancouver but there is no simple reliable way to find them. If I wanted to pay for two days travel time, plus travel expenses and accomodation, on top of the consulting fee, I could get an in room measurement but I wouldn't have any money left over to actually treat the room (and this is based on a budget for acoustics of about $10 000). I agree that the finest results would come from an in room consultation to tweak things both by ear and by measurement, but I think (and there are many published reviews to back this up as well as it being the standard operating practice for many well respected acoustic treatment companies like Acoustic Sciences and Rives) that a mathematical model of the room based on sound basic acoustic principles can get you 80-90% of the results of the in room consultation with a lot less hassle.
