In my case I was very impressed with the Sound Anchors. I have a pair made for the Thiel 3.6 speakers.
I started with some Sistrum SP004's. They (compared to the factory spikes) seemed to provide a lot more low-level detail, subtle decay of instruments, and more precise depth in the soundstage. However, they seemed to lessen the impact of the bass. Since they fit inboard of the plinth of the speakers, they also made them quite tippy.
I had a chance to move to the Sound Anchors, and overall I really prefer them. The whole rhythm section really comes alive (deeper, more powerful bass, stronger slapping on drum heads, more power in guitar chords). I am probably giving up a little of the subtlety and detail of the Sistrum, but am gaining a lot more in the rhythm section. Overall this is a good tradeoff for me. Either brand is way better than the factory spikes. Hope this helps.
