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.
