I also support the recommendations for Sound Anchor stands and have used them under speakers, amps, and electronics for years. Target’s literature says;
Target Audio Products Stands are 100% thick steel, substantially heavier and of vastly more rigid construction than any other speaker stands available.
Not sure they are heavier than Sound Anchor but both are made from heavy steel, both are fillable (SAs come already filled), and either should work great. I like the spikes that come with SA stands and they are easy to level and align so all four spikes are evenly in contact with the floor. However, IMO for a sonic improvement, even better than spikes would be to decouple with Herbies Giant Fat Gliders, Giant Fat Dots, or spring supports.
