The XP5 XS is an outboard power supply upgrade, it offers a significant improvement in performance when used with any of the following Naim products:
- ND5 XS network player
- NDX network player
- NAC-N 172 preamplifier
- NAC-N 272 preamplifier
- DAC digital to analog converter
- HDX music server
The casework is in excellent condition with only minor imperfections on the top plate (and only visible in certain lighting conditions), it comes complete with Naim power cord and Burdy cable, I know how Naim people are so I'll tell you up front that the unit is four years old.
