What customers say
The Aurorasound AFE-12 MC Step-Up Transformer is highly regarded by audiophiles for its exceptional sonic purity and value. Users consistently praise its natural, dynamic sound signature, noting significant improvements in soundstage depth and instrumental separation. A key feature is the remarkably low noise floor, which reveals subtle musical details against a silent background. While positioned in the high-end market, many consider the AFE-12 a genuine bargain due to its performance, often exceeding much costlier units. Its robust build quality reflects meticulous engineering. This component is widely viewed as a transformative upgrade, delivering immersive, reference-grade vinyl playback for serious analog enthusiasts seeking precision.
Know before you buy
The AFE-12 is a step-up transformer designed to bridge the gap between low-output Moving Coil (MC) cartridges and standard Moving Magnet (MM) phono inputs. It boosts the signal level and adjusts impedance so your cartridge can perform optimally with your existing phono stage.
The AFE-12 features three settings: Low (0.7–10 Ohms), Mid (11–30 Ohms), and High (31–100 Ohms). You should match the setting to the internal impedance of your specific MC cartridge; if you are unsure, start with the setting that most closely aligns with your cartridge manufacturer's recommended load.
No, the AFE-12 is a passive device. It utilizes high-quality Lundahl transformers to step up the signal, meaning it does not require electricity and will not introduce power-related noise into your signal path.
The internal cotton stuffing acts as a mechanical vibration damper. By minimizing micro-vibrations within the aluminum chassis, it helps ensure the signal remains clean and free from the coloration that can occur when components are affected by external resonance.
It is designed to work with any standard Moving Magnet (MM) phono input. Simply connect your turntable to the AFE-12 input, and connect the AFE-12 output to your preamp’s MM input.
Lundahl transformers are highly regarded in the audiophile community for their transparency and technical precision. Using an amorphous cobalt core, this specific transformer preserves the detail and dynamics of your vinyl without adding unwanted character or distortion to the sound.
