Supercap DR


The use of a separate Naim ultra-low noise power supply such as Supercap DR brings substantially improved musicality to the whole system, improving timing, dynamic range, clarity and order. SuperCap DR can be used to power all Naim preamplifiers (except the NAC-N 172 XS and NAC 552), Superline phono stage and active crossovers, and is the only choice for supplying power to the NAC 252 preamplifier.  Inclusion of a SuperCap DR offers the additional benefit of allowing the preamplifier to be left switched on constantly, independently of the power amplifier, keeping the unit’s complex circuitry fully stabilised at all times.

This product qualifies for free, remote installation by one of our technicians.

SuperCap DR – Powerful and versatile.
As iconic as it is widely acclaimed, the SuperCap DR is a Naim Audio classic, capable of powering every preamplifier in our range except for the NAC-N 172 XS and our flagship, the NAC 552. Its substantial toroidal transformer and high-quality smoothing capacitors combine to ensure improved timing, clarity and dynamic range from your favourite music.

Upgraded with our new DR voltage regulator, this timeless component remains one of the most well know and oft-employed power supplies in our range, and for good reason.


  • 13 x 24V outputs, 2 x 12V output
  • All-new Discrete Regulator (DR) configuration, delivering Naim Audio’s best-ever standards of stable, low-noise power
  • Brushed, black-anodised aluminium chassis

Technology & Craft
Each of the multiple power outputs on the SuperCap DR uses Naim Audio’s specially designed discrete regulators for optimum performance. The SuperCap DR can be used to power all of the Naim Audio preamplifier (except the NAC 552 and NAC-N 172 XS), Superline phono stage and active crossovers, and is the only choice for supplying power to the NAC 252 preamplifier.

Its anti-vibration, resonance-controlling feet complement the elegant new cast and extruded anti-magnetic chassis to protect the sensitive internal components from resonance and microphonic vibration.

The SuperCap DR 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.
