This system consists of 4 Wood Block AC RFI filters for components with IEC power inlets and 4 pairs of Red Rollers for treating each end of interconnects. All units have very light use as I discovered the Bybee Purifiers a few months after purchasing the Versa devices. HOWEVER one wood block was opened to see the exact construction of the device and then screwed back together, see the photo, but it works perfectly.
These devices made a definite improvement in my CAT Signature and Defy 7 components prior to my Bybee days. These devices cost $1,260 when new.
The following comments by respected authorities highlight the need for RFI filtering ...
"The Versalab Life Support System revealed the sonic gains that can be realized from RFI filtering. You owe it to yourself to hear the difference these products can make in your system. I think some of the hash attributed to digital components may actually be RFI rearing its ugly head. I use a strictly digital front-end, and I must say that I now feel less compelled to replace it. An analog setup may benefit as well, although I did not try one during the review. I suspect actual results will vary depending on your components and the amount of RFI actually present in your area.
I did not find myself increasing my normal preamplifer settings, so I’m not sure exactly how much noise was removed. However small the amount, though, it was significant. You can be certain that these products do as they claim. In my case, the overall noise floor was lowered and dynamics improved. The sonic signature of my system remained intact, but strong areas became stronger. A veil was removed, revealing a clearer sonic picture. Versalab should be commended on solving a problem most of us didn’t know we had. Give the Life Support System a try. You may be in for a newfound appreciation of your audio system and music collection."
"The other problem that we are fighting, whether it is computer-based audio or conventional sources is the horrible RFI pollution that is getting worse and worse. Everyone has cell phones, Wi-Fi, and Bluetooth gadgets. All of this stuff has an impact. And these frequencies make it difficult to deal with effectively. It's like the slime from an old sci-fi movie—it gets everywhere."
