The XPS is a simple and effective upgrade to enhance the music-making ability of your Naim Audio source component. As one of our most flexible performers it can be used to upgrade our CDX2 CD player and DAC digital to analogue converter, and it is also suitable for use with our NDS, NDX and ND5 XS network players and HDX hard-disk player/server. Its large toroidal transformer features four separate windings, coupled to six low-noise regulators and benefits from Naim Audio DR voltage regulator technology.
