I used sound anchor stands for my Harbeth SHL5+ and the bass sounded significantly better than the ton trager stand copies I made.
I liked the appearance of the ton trager knock offs but the solid, massive sound anchors delivered the tightest, deepest bass. i had them spiked through carpet to concrete floor. I discovered sound anchors at a local dealer where all of their speakers had excellent bass because of them, I was sold.
1- if you do have the tragers made- definitely pay attention to stand height. to my ears harbeth speakers sound best when they are lower than typical. it reinforces the bass and gives the tweeters a softer more natural blend- just an inch or two below ear height. ideally you should experiment before committing to the height.
2- without question use iso dots to decouple the speaker to stand. very critical for lossy cabinet speakers.
soft sorbothane made for peaky bass, medium firm dots made the best most balanced bass and hard silicone rubber dots seemed to drain the bass, experiement,
