I own a rs130 and rd160 combination. I can tell you the SFP connection is superior to USB. The overall sound quality is simply stunning. I also have a Weiss dac and McIntosh Ma352 in my second system, and the Hifi Rose is leagues ahead, the technology is newer, better, and offers thrilling detail retrieval, dynamics, and effortless control that gives some of the best bass I’ve heard in my system .
