Excellent stands, in both quality and design
Very well made, and well designed. With or without filling with sand they are stable and solid. Filling with sand adds the right amount of centralized weight and deadening. They hold about 10 small drinking cups of sand each, I'm guessing 3-5 pounds worth.
Aside from some minor finishing defects on the back of one stand (the defects aren't very visible, but can felt and will grab cloth), they look great. Very "studio" in appearance. They are almost invisible in a way, both visually, and sonically. Strictly speaking, the height (with rubber feet) is about 1/4" to 1/2" taller than 36".
In use, they are proving to be exactly what I was after. I had looked at every other stand made, and decided on these over much more expensive stands. While made in China, the QC seems top notch, aside from the aforementioned cosmetic issue.
Assembly was simple and straightforward. They fit my Dynaudio BM6 monitors perfectly.
