I use an Arcici stand, spiked to a cement slab floor, inside a "closet" away from the speaker area, and even in that sirtuation it improved the music presentation with greater clarity to my amazement. There's no explaination for this improvement as there shouldn't be any air (different room) or floor (slab floor) bourne vibrations that can get to my equipment where it is located. It must be the mass loaded stand it self. I'll swear by it as one of best $/Value improvements I've made. It may or may not work as well for you, but it damn well worked for me.
