Naim Audio Hi-Cap DR power supply

Naim Audio Hi-Cap DR discreet regulator external power supply.


What we Say:

The Naim Audio Hi-Cap DR power supply is a flexible performance upgrade product. It can be used with a wide range of products and in every case improves the performance of that product.

It is essentially a linear power supply. Naim have been making the Hi-cap power supply for decades but the latest DR version moves performance on significantly from the original. It still features a large toroidal transformer. It still features large high quality smoothing capacitors but now no longer uses bought in regulator devices. Naim have now developed their own discreet regulator devices. These used to buy in devices and then hand select the best ones  to make sure the supply was as quiet as required.

The new DR module is much quieter than previous versions. This means one thing, more music from your Naim system.

The Naim Audio Hi-Cap DR can be used in a range of ways. It can provide clean power to pre-amps such as the 202 and 282. It can be used to power the pre-amplifier stage of the Supernait 3. It can be used to power turntable accessories such as the stageline and superline phono stages. It is a great building block to improved performance.

What they say:

HiCap DR

Compact power.

It may be small, but the HiCap’s talent for maximising your system’s musicality should not be underestimated. A compact power supply partner for almost all of our preamplifiers plus our phono stages and active crossover components, its large toroidal transformer and generous, high-quality smoothing capacitors ensure excellent performance and value. NAC 282 preamplifier owners can enjoy even better performance by adding an additional, second HiCap to their system.

  • Two 24V power outputs
  • All-new Discrete Regulator (DR) configuration, delivering Naim Audio’s best-ever standards of stable, low-noise power
  • Bead-blasted, black-anodised aluminium chassis plus anti-vibration, resonance controlling feet
Technology & Craft

Each of the power outputs on the HiCap use Naim Audio’s specially designed discrete regulators for optimum performance. The design can be used to power all of the Naim Audio phono stage preamplifier, active crossovers and preamplifiers except the NAC 552 and NAC 252. In the case of the NAC 282 preamplifier a second HiCap may be used, bringing further improvements. The addition of anti-vibration, resonance-controlling feet complements the elegant new cast and extruded anti-magnetic chassis to protect the sensitive internal components from resonance and microphonic vibration.

The HiCap was updated in 2012 as a result of a two year project to develop a new discrete regulator (DR) for Naim Audio power supplies. The new Naim Audio DR now features, alongside improvements to the wire routing, mechanical decoupling and internal layout. These enhancements, developed through intensive listening tests, significantly raise performance and make music even more communicative and enjoyable.
