Features
The 2M Bronze features a Nude Fine Line diamond, which is particularly suited for demanding applications. The slim profile of the Fine Line stylus will track even the highest frequency information. Additionally, its larger footprint ensures reduced distortion and record wear. The 2M Bronze uses a special upgraded engine, featuring split pole pins with a silver plated copper wire.
Replacement stylus unit
2M Bronze (interchangeable with 2M Black and 2M Black LVB 250)
Stylus lifetime
With proper care we find that up to 1000 hours is possible without degradation of performance.
2M Series styli interchangeability
The 2M Series’ engines, coils and magnets configurations are not identical: Red and Blue are identical, so are the Bronze and Black and so are the true mono variants 2M Mono and 2M 78. Likewise, 2M series styli are interchangeable within the below combinations:
- 2M Red, 2M Blue and 2M Silver
- 2M Bronze, 2M Black and 2M Black LVB 250
- 2M Mono and 2M 78
Compatibility with Rega brand TT/TA:
REGA brand cartridges’ height from stylus tip to the top cartridge mounting surface is lower than standard. Therefore you would need spacers to ensure the correct set-up of the Ortofon cartridge. Please read about cartridge set-up and alignment on tonearm on our FAQ.
Adjusting the height of your Rega tonearm is easy with Acoustic Signature’s Spacer Set. It allows you to adjust the height from 0.5 mm to 3.5 mm in precise steps of 0.5 mm – without removing the tone arm. Simply loosen the screws, insert the AS-spacer, then lock the screws back down, and you’re tonearm is ready to play.
3.2 – 4 mm spacers should be enough for 2M cartridge.
