Description
The Naim NPX 300 is a dedicated external linear power supply that brings a significant upgrade to any compatible Naim 200 or 300 Series source or preamplifier. By replacing the internal PSU, it reduces noise and lets the connected component concentrate solely on signal handling — often resulting in better resolution, tighter bass, clearer textures and greater dynamic freedom.
This pre-owned unit is in excellent cosmetic and operational condition. We’ve checked all outputs and verified correct power delivery, including standby behaviour and logo illumination. It ships complete with the provided Burndy cables, Power-Line Lite mains lead, documentation and is immediately ready to integrate into your system.
If you pair the NPX 300 with a streamer or pre-amp — for instance the NSC 222 — you’ll notice improved clarity, more stable background silence and a more coherent, muscular delivery. We’re happy to advise on ideal matchings and system configurations so you get the most from this power supply.
