Just purchased the RS520, either I haven't found the solution, or an update that can enable such a setup. I would like to use my external R2R ladder DAC via RS520 USB out, and then use the GaN amplifier section of the RS520 by using the RCA inputs on the back of the RS520. Similar to the old tape monitor loop in vintage audio equipment. Since the RS520 is all software driven, it seems that this could be accomplished via a firmware update. This would make the RS520 the absolute leader in streaming DAC integrated amplifier market.
