I'm using RealTraps MiniTraps bass trapping and Auralex 2" studiofoam in my room (my listening room doubles as my recording studio control room).
The difference is quite notable. Your room is part of your system and flattening your room's response as much as possible by treating unnecessary reflections, standing waves, low frequency modes etc is quite important. I still don't have my room ssounding quite as I'd like it and need to order some more treatments (keep in mind I'm doing critical audio production as well).
Even with in its unfinsihed state, my room has improved. The treatments I've tried thus far have improved bass clarity and extension, opened up the soundtage, and provided overall more tonal clarity--and I still have some problematic reflections at that.
