I have 9 of the SR Cable Risers in my system, which has two 10' SR Atmosphere Level 4 speaker cables. I got them because I have carpet in my dedicated listening room and I was worried about static build up within the cable, particularly in the drier winter months. Their design is superior to others, including Nordost, because of how they insulate against static transmission.
Do they make a noticeable improvement in system (i.e. speaker cable) performance? Its hard for me do say because I have had them in place for a few years. I have not bothered with an A/B. I will say two things about them: first, I can't recall a noticeable performance uptick when I installed them, so there may not have been one in my system; and second, I really like them because they make the speaker cables more noticeable so I don't have folks stepping on them and it allows for easy vacuuming without having to lift the cables all the time.
The paradox is these admittedly expensive risers likely work better, from a performance perspective, on cheaper speaker cables. Well constructed cables with excellent insulation or isolation from RFI and other forms of transmission interferences likely don't benefit as much from cable lifters.
Bottom line is: each to their own, and if you like the look and intuitively presumed benefits then what the hell. I will say they look good.
