MC Step-up Transformer - Airtight ATH-2 Reference

VAT included in price for European Union countries and may be adjusted based on delivery country at check-out.
Average shipping time : 4 to 5 weeks. Shipping is free within European Union (except for specific territories) above 99€ purchase up to 50kg. Shipping costs on quote above 50kg – quote request to be send to : There is no return policy for countries outside of the European Union.

The ATH-2 REFERENCE has three selectable inputs, i.e., "Bypass", "2 Ohm" and "40 Ohm"


Thanks to the employment of the new winding material (oxygen-free copper) and careful review on its winding method, the dynamics-range, sonic powerfulness and quality feelings have been remarkably improved, thus achieving an unparalleled affluence in terms of musicality of analogue discs.


The frequency rage being fully procured, the upper-end is extend up to 80kHz (-1dB) and 120kHz (-2.2dB).


The S/N ratio especially at the low output level totally surpassing the competitors' performance, you may enjoy the higher quality in the different dimension in combination with the Hi-End amplifiers.


To say nothing of the 2 Ohm position that complies with the latest ultra-low impedance below 1 Ohm, the ATH-2 REFERENCE derives the full potentials of the existing MC cartridges, starting from the Ortofon SPU down to the latest ones



  • Input Selector:3 position
    • Bypass: without gain, for MM cartridges
    • 2 Ω (0.6Ω~7Ωapplicable) gain 29dB 
    • 40 Ω (7Ω~40Ω applicable) gain 23dB
  • Frequency response: 10Hz~80kHz (-1dB)
  • Dimensions:240(W)×180(D)×70(H)mm
  • Weight: 2.8kgs


Why use a transformer?

Step-Up Transformers (SUT) are a serious option for anyone who owns a Moving Coil (MC) cartridge, one that can significantly improve both the sound quality and sonic character.  Quite simply, a good transformer is the best way to audition an MC cartridge with the highest performance possible.

Since the output of MC cartridges is lower than that of a Moving Magnet (MM), higher gain is required to utilize them, such as that provided by SUTs or MC phono preamplifiers.  Although both devices provide this requirement, both are fundamentally different in function and in sonic character.  This is where SUTs are frequently seen as superior; they are completely passive and offer exceptional noise performance and sound quality.

This is due to the fact that the structure of harmonic and intermodulation distortion is fundamentally different between MC-preamps and SUTs. While an MC pre-amplifier has a constant resistive input impedance, an SUT has an input impedance that is frequency dependent. The harmonic distortion produced by SUTs is highest at the lowest frequencies and drops as the frequency rises, whereas in most MC preamps the distortion increases as the frequency rises.  Combined with significantly lower Intermodulation Distortion (IMD), the sound produced with an SUT will be much more open, dynamic, spacious, and natural.
