ozlfly: i quite agree with albert about the importance of a sound foundation (pun intended) before applying acoustic treatment. two of the best rooms i've listened in have quite different foundations. the first applied construction much as albert has suggested but uses dual stud walls; this system employs room-within-a-room construction with two 2x6 decoupled stud walls, each covered with double thicknesses of 5/8" drywall and each wall lined with acoustic dacron "insulation." a 2" air void between the walls adds to the sound isolation in both directions. the second "foundation" is comprised of brick laid inside two-foot thick stone exterior walls (not practical, agreed, unless you've bought a cottage in the cotswolds). check out the chord audio listening room (in kent, england--no, not the cotswolds) for an example of a "brick interior" sound room:
