Any exp. w/ Shunyata Dark Field Cable Elevators

Simple point I'm making is that no company would survive in todays market if it wasnt for a severe markup for this kind of gear as for anything else in the retail market.Also I'm not bashing any product of Shunyata.If one tries it and likes it,then they should buy it.

Since these are made of foam, will they deteriorate after a number of years, like some speaker surrounds?

I must first apologize to Grant and the people of Shunyata, I am the bad guy. I usually don't make posts like I did initially but, My god $250 for twelve pieces of foam. Well, I did feel bad and ordered a set. My dealer would take them back if I didn't want to keep them, which I was sure would be the case. Well I was wrong. They are made of a foam that is quiet unlike what I assumed that they were. (What did someone once say about "Assume"). But they really were a nice upgrade. I will post a review as soon as I get back from a sudden trip but I will say this, I ordered a second set to complete all my cables. I think that they are a very reasonable upgrade to a system, improvements in clarity that exceed other upgrades I've made such as Stillpoints. But more later, I will post the details of my audition and experience when I get back. But again, my apologies to the folks at Shunyata, you created a fine product.

David,

were you using other cable elevators prior to the DFEs? I've got polycrystal coated ceramic isolators and I've been looking at the DFE's with interest!

Adhaney, I have not used any other cable elevators or isolators with my current system. I did try some Music Direct ceramic with an older system in a very noisy building and noticed no benefit or musical loss but it was not a very fair trial.
