While an Anechoic Chamber is a great place to analyze sound and sometimes benificial in some aspects of recording - not such a great environment to listen to a live performance, as is completely dead and sterile.
The floor in my listen room is carpeted, with heavy acustic drapes on the wall behind the speakers and otherwise normal furnishing - sofa, recliner, coffee table etc. My system is set up on a relatively cheep, but sturdy 3 shelf rack, I have had great success using grade A, 2" slab cut, Black Walnut boards (approximately 18W x 15D) isolated from the rack shelves with 1/4" felt/rubber iso pads. The components are coupled to the boards using brass cones, with a thin felt disc between the base of cones and component.
I agree with what Michael and others have said, while taking care of unwanted resonance is important, we can sometimes go too far - live music, in its' real environment, is full of resonance and texture, not dead and sterile.
Am plenty happy with my system, rack and room as they are now. I could have spent a lot more money to get the same or lesser results and as is - my system, in my room, has just the right balance of detail and clarity with enough fullness and lushness to be musical and engaging......Jim
