Sculpture A cartridges were born from a desire to adapt modern tip profiles to a classic Denon 103 generator. Although it retains very few parts from the original unit, the original Alnico magnets still prevail. A new dual structure body was developed which allows damping and shielding of the generator from both internal and external vibrations. This new structure also helps achieve specific stylus tracking angles for each of the different diamond tip profiles Sculpture A use. Each of the tip profiles has its advantages and sonic benefits, allowing you to choose the specific presentation that suits your taste and synergises best with the rest of your system.

The A .4 series aims to achieve the highest possible performance by incorporating hand wound copper or silver coils for impedances over ten times lower than that of the original Denon DL-103. It is the lowest impedance cross-coil design with AlNiCo magnet available today and this just one of the reasons why it sounds so vivid and natural.

The A.4M uses a Nude Micro Ridge tip profile, a boron cantilever and is a low output design, meaning that it needs to be mated with a corresponding Sculpture A Mini Nano step-up transformer to boost the signal strength. Note that for the audiophile purist, there are some advantages to the low output cartridge designs as they pick up more information and have a more refined, sophisticated sound.

The Nude Micro Ridge tip profile almost exactly duplicates the shape of the cutting stylus used to produce the original master disc from which records are made. This enables it to track portions of the groove other styli simply cannot reach. The result is extremely accurate tracking of high-frequency passages and ruler-flat frequency response within the audible range.

The unique multilevel “ridge” shape of this tip wears more evenly, allowing greatly extended record and stylus life.
Resolution is markedly improved, as can be expected from a profile with an even narrower minor radius. Sonically, there is a sweeter quality, more clarity at higher frequencies and less fatiguing over an extended period. It is very smooth with excellent timbral texture & dimensionality. Yet it is also dynamic and energetic. The sound produced by the A.4M has this rare ability to envelop you in the musical event and engross you wholeheartedly. You drop the stylus into the groove and you are ‘transported’. Beguiling!
