Product Description

Vinyl replay makes a huge contribution to the enjoyment of recorded music. At its best, vinyl has a uniquely engaging and musical quality, and with the SuperLine phonostage, the best of vinyl just gets better.

The SuperLine is a high performance moving-coil phono stage built in the Naim Audio aluminium reference enclosure with an anodised front panel. It brings all Naim Audio’s latest analogue electronic design and environmental isolation techniques to bear on the most delicate analogue element of any hi-fi system – the moving-coil phono signal. The SuperLine requires an external power supply – either the power supply output of an appropriate Naim Audio preamplifier or the SUPERNAIT and NAIT XS integrated amplifiers, or, for optimum performance, a dedicated FlatCap XS, HiCap or SuperCap.

SuperLine brings out all that’s best in vinyl replay – timing, pitch accuracy, clarity, detail, and the unmistakable naturalness that records can deliver in abundance.

Technology & Craft

The heart of the SuperLine is a new, two-stage single-ended Class A discrete amplifier with part-passive RIAA filtering that runs off 25 internally regulated power supplies and features the transistor “quiet room” thermal isolation technique originally developed for the NAP 500 power amplifier. Environmental isolation is also ensured by the SuperLine’s massive sub-chassis and high-Q spring suspension system – used here for the first time on a phono amplifier.

Duplicate phono and BNC sockets provide input versatility, and cartridge impedance matching adjustment is provided by four resistive and three capacitive load plugs. In combination with the SuperLine’s internal input load, twenty different standard load combinations are possible

The SuperLine is also available in a lower gain model, SuperLine E. The SuperLine E is identical to the standard SuperLine except that is has been designed for use with cartridges that have a higher output voltage than most popular moving coils: for example high output moving coils.

  • Bead-blasted, black anodised front panel



Naim Audio began in the 1960s when racing driver and audiophile Julian Vereker started recording live performances. He soon realized that none of the components on the market could recreate the sound as he wanted. So, as a self-taught engineer, he built the solution himself with the NAP 250 power amplifier. Since then, Naim Balanced Audio has leveraged mechanical and electrical engineering to design cutting-edge audio products. They've grown from a modest shop in England to over 200 employees and gained a devout following from music lovers worldwide. Their range of products includes streaming players, turntables, CD players, DACs, amplifiers, power supplies and cables. Each delivers high-performance audio through expert circuitry, deliberate materials and build, and expert engineering. The goal is finding the 'The Voice of Naim' with no coloration or interference. Their quality is so exceptional that Naim is the go-to partner for Bentley audio systems. The Naim Uniti Atom is a great example of the company's forward thinking. This streaming player brings the award-winning Naim performance in a beautiful design. All while delivering a modern listening experience with native Spotify, Apple, and Tidal streaming. Also listen to digital music through AirPlay, Chromecast or Bluetooth playback. As a nationally recognized leader in the field of high-end audio and home theater, Overture is a proud dealer of Naim audio components, selling customers the best audio components from Naim in Sales Tax Free Delaware.
