Martin Logan Request spikes

Has anyone try any other spikes than ML supply with
the speaker ? What about the ETC spikes of ML ?
Have you notice any improvement ?
Thanks in advance
I personally don't own a pair of Martin Logan Request but do own two pairs of SL-3 and have been using the ETC spikes for all the speakers. It lifted the bass and sounded a lot more detailed. I really like them a lot but don't know why they have to be so expensive. But with the result I got back I guess I can't argue. Good Luck.

I have used a set of audiodyne super spikes on my SL3's and what a great improvement over the standard spikes.
