Step-up Transformers by Murasakino
Designed for their Sumile cartridges, with their extremely low DC coil resistance, these transformers are an excellent option for the likes of Lyra, MY Sonic Lab and such.

Nobala - $8,495
Nobala
Optimized for the Sumile, the Nobala has slightly higher upper frequency extension than the MG 510.
While this might seem superfluous, this yields less phase shift in the audible treble range with the result being a more pure harmonic rendition.
The Nobala is optimized for the Sumiles and other cartridges with similarly low internal impedance (DCR).
Extreme measures are taken to both damp and shield the Nobala, with a three-layer construction protecting the transformer: an aluminum plate, followed by a 2-mm-thick pure copper shielding layer, and finally, its machined aluminum case.
Premium parts are used throughout, including Cardas RCAs. All machining and assembly is performed in Japan.
Frequency Response | 60 - 70 kHz |
Step-up Ratio | 26 dB (1 : 20) |
Recommended Cartridge DCR | <= 5 ohms |
Dimensions (w x h x d) | 166mm × 95mm × 155mm |
Weight (approx.) | 2.6kg |
MT510 - $5,000
MT510
Designed for a bit broader range of cartridge compatibility than the Nobala, it will still mate well with the Sumile as well as other cartridges with low internal impedance (DCR).
Similar to the Nobala, the MT510 pays attention to mechanical damping and shielding, with an aluminum layer, followed by a 1.6-mm-thick iron shielding layer (the base is 2.3 mm thick), and an 8mm thick aluminium panel with a thickness of 8 mm.
RCAs are made by Neutrik. As with the Nobala, the transformers and chassis components are made in Japan.
Frequency Response | 60 - 58 kHz |
Step-up Ratio | 25 dB (1: 17.8) |
Recommended Cartridge DCR | <= 12 ohms |
Dimensions (w x h x d) | 160mm × 79mm × 110mm |
Weight (approx.) | 1.8kg |
