I have them in both Brass and Titanium - and honestly, I hear very little improvement.
They are awesome for sliding the speakers around without damaging the floors though.
Keep in mind, while they look like the off-the-shelf floor protectors (which they are) they are filled with Herbie's damping material, then use a metal (I think the choices are Brass, Steel, or Titanium) to help sink your vibrations into the damping material from your spikes.
Like I said, I saw very little improvement, but I admit I've not given them a fair trial, nor have I done a more recent with/without test now that my speakers, amp, and DAC are broken in, plus the new resolution on the latest DirectStream firmware. So maybe if I gave them some time now I'd actually notice something. I also don't have the best spikes out there...they are simply threaded steel spikes from china and nothing special.
Again, awesome for protecting the floor and/or sliding around.
