I have a Furman IT-Reference 20i for sale. This is the newest version and is their top of the line. It's the best I've owned and I've had Richard Grey, Monster, and some PS Audio. Every single individual outlet is isolated from the others and the unit isn't current limiting. In fact, with power factor correction, you actually WANT to plug in your amps and high current devices. It even offers protection for your phone and cable lines. It's one of the best, if not THE best power conditioners out there. It filters, isolates, and provides you with current reserves.
The unit is in nearly new condition. I can't find anything wrong with it, other than being a bit dusty. It comes with the original 20A power cord as well as its original packaging, so shipping won't be an issue. I was a Furman dealer before I got out of the business and I've had it in my own personal system for a couple years now. It's been sitting in a Salamander cabinet, behind a door for its entire life.
