There are a number of good sources for acoustic information. "The Master Handbook of Acoustics" is a great book, but much of the information isnt applicable to the 2 channel room.
I have found GIK Acoustics to offer good advice and they have some reasonably priced products. Do some research and talk to a few companies that sell products of this type. Also check out some of the free information and services offered on these sites. Much of these products you can make yourself if you are of a mind.
So much to cover and so many things that can be done to a room for pennies when you compare these costs to that of equipment. My advice is to decide which are your highest priorities with your system (dynamics, organic quality, detail, etc) and then post here again. If you can isolate your single highest priority this would be great.
I have a problem with people blindly providing names of products, and I have done this myself, without asking the proper questions. I would avoid professional reviews, hold owner reviews in a bit higher standing and listen as much as possible to different systems. If you can, go to any of the various shows just to get a feel for what type of sound you like.
I think that Ralph at Atma-sphere gives good advice as does Duke at Audio Kinesis. I am sure there are many others. The people that dont give you quick answers and ask additional questions are often the ones to listen to the most.
