I listened to the risers at Rocky Mountain last year. Did it make a difference? Yes. With many tweaks it's often about the visceral feeling of the music, ie is it less fatiguing, do your shoulders drop when you listen, smooth out subtle edges/sharpness etc. vs. changing more obvious attributes such as sound stage, imaging, etc. These risers definitely changed the visceral feeling of the music. I don't know if they are better or worse than using wood or ceramic risers because SR didn't do A/B with other risers, just with and without. Like everything your mileage will vary so if there price is right and you like the look of them , may be worth a 30 day try. Since these do have the proprietary transducers, they will definitely sounds different than comparable risers without them. Also the difference wasnt night and day and you will want to add these to an already highly revealing/resolving system.
