Naim NPX 300 Power Supply - Optimised power and performance

Reach a higher level of musical performance with the NPX 300 power supply for the 200 Series sources and preamplifiers, including the NSC 222 streaming preamplifier.

NPX 300 deactivates the internal power supply, immediately reducing noise, and provides a superior, cleaner power supply. You can connect several NPX 300 power supplies within the same configuration for an exceptional musical experience.

Controlled power

The NPX 300 incorporates a new transformer, which works with six exclusive Naim power regulators (DR technology - Discrete Regulator), providing a cleaner power to your system. Less “noise” means a better sound! NPX 300 works perfectly with the 200 Series products, and is also compatible with the NDX2 or even the NAC-N 272 – you just need the correct legacy cable.

Inspired by the best

At Naim, all their choices are made with the aim of creating a unique emotional connection with music, and offering you the best products in their category. The NPX 300 includes a certain number of innovations used on the flagship Naim 555PS DR power supply, such as the separation of the digital and analogue power supplies via dedicated Burndy cables.

The story of Naim and aluminium

Naim’s founder, Julian Vereker, immediately understood the many benefits of aluminium as a material for wrapping Naim electronic components. He knew that delicate audio components are very sensitive to the effects of magnetic fields, unstable temperatures, unwanted vibrations, etc. While other manufacturers were bending thin sheets of steel, Naim used thick plates of aluminium.

The Naim Classic range maximises this highly technical and durable approach, with aluminium housings rivalled only by Statement, their flagship £205,000 amplifier. Naim chose a superior-quality aluminium, which optimally combines thermal and microphonic properties. The front panels are treated with solid 20mm-thick aluminium billets; heat sinks frame the side panels and 5mm plates cover the top and bottom surfaces of the products. The aluminium is brushed, sandblasted and anodised to guarantee unalterable beauty throughout the product's life. The New Classic range can be immediately distinguished with one look and one touch, before the first note of music even plays.

Perfect for work! I use it for laptop, charger and few items necessary at work. I have a few blocks to walk from parking to work location and this bag has replaced last backpack and purse. Much easier to carry one item than two or more. Plus, it has enough room if you need to use it for clothes and toiletries (road-trip) or carry-on.

Size up
While I like the concept, it’s not true to size. I cut the tag off thinking this fit well, as I wear 38G in most HSIA bras, I found that throughout the day this rode up and gave me “quad-breast.” It also broke the skin on my back where the anti-slip rubber was on the band. It has potential, maybe if you size up with band and cup.
