I might use them a little differently than most. I recently bought a new line stage for my high end audio system. I modified my latest preamp to provide two sets of RCA jacks to route its output to both the power amps for my main speakers and the line in of my subwoofer. My new line level only had one RCA set and the other was XLR. I used them to convert XLR to RCA and connected a subwoofer cable to it. It works great with no noise and allowed me to perfectly balance the sound between the subwoofer and the mains. I'm not sure how reliable they are for regular plugging and unplugging, but for my system, where I installed them and left them there, they do their job well.
