A speaker stand that sounds bad with a particular pair of speakers may work wonders with another pair of speakers. The reason for this is simple. It all has to do with how efficient the stands can drain away the vibrations created by the workings of the woofers. If your sound system is muddy-sounding, lacking in focus and booms- your speaker stands could be at fault. If the stands are solid, of high quality and expensive, and your system still sound this way, it could be due to misuse because of a poor understanding of how the stands work.
If your speaker stand is one of those cheap, lightweight products and thus not too efficient at the transfer of energy, the speaker it is supporting tends to trap the vibrations in the speaker's cabinet creating that boomy and muddy sound. This is especially so if your speakers are of moderate quality where the cabinet construction are often lightweight. This problem affects not only the bass but also smear the highs as well. The tweeter produces frequencies whose wavelengths are in the regions of microns. If the entire tweeter itself is vibrating due to the woofer, it will not be able to recreate those fine , delicate high frequencies properly. This situation is similar to the common experience of trying to read in a moving vehicle. The attempt will most likely give you a headache unless if you ride in a Rolls-Royce.
If your speaker stands are supposed to be the Rolls-Royce of stands and your system still sounds muddy, then maybe you are not using them properly. Maybe you have stuck blu-tack or some other soft compound under the speakers. Or instead of hard spikes on the base of the stands, you have replaced them with something that's not so unfriendly towards your expensive floor. Most likely something soft again. Using a soft, dead material between the speaker and the stands, or between the base of the stands and the floor results in decoupling. This impedes the efficient transfer of vibration energy from the speaker to earth, which provides an infinite mass to absorb such disturbances. Replace these with some hard cones such as ceramics, hardened steel, crystals or tungsten carbide bits. Cones commonly make from aluminum, brass or mild steel are not really hard but are still better than blu-tack or rubber feet for the job of maximal coupling.
In certain situations, a "bad" speaker stand may actually sound better than a high pedigree unit. I can see this happening in some hifi system where the equipment have a tendency to sound thin, bright and without much bass weight. If the stands are too efficient at draining away vibrations away from the speakers, they may exaggerate the problem. Thus it may be a good idea to use blu-tack, rubber feet, sorbothane or some other soft compound to decouple the speaker from the stand. Personally I do not see this as a long term solution to such a problem because the speakers will never get a chance to sound their best.
To sum up the discussion so far, a pair of speakers sounds best on stands that drain away just enough vibrations. Not removing enough results in the system sounding muddy and boomy. Remove too much and the sound becomes overly tight, lean and less musical. The audiophile's best bet is to buy the best pair of stands he can afford that is one that is extremely efficient in removing vibrations, at the risk of making the speaker sounding lightweight. Then it is relatively easy to tune the efficiency of the stands down to a point where it matches the speakers. Whereas it is much harder to improve the efficiency of a poorly made stand.
