No disrepect, to everone that can't believe cable isolaters work. I think you have to consider the cable route and shielding. I have Kimber Bifocal XL's over a berber carpet. When I added glazed ceramic elevators it improved or removed smear from what I thought was a great sounding system. I tried the experiement on my wife who could care less and she felt the elevators improved the sound. I'm in the data communications industry and cable type is critical in data communications for speed and accuracy. Also as everyone knows the cable route can effect sound. Like every thing in this hobby a person should experiement for themselves. Some improvements are real some are imagined(placebo effect). At the end of the day any tweaks that improves your listening pleasure is valid to YOU.
Enjoy your system Tweak reasonably.
