Ortofon 2M Black LVB äänirasia
Ludwig van Beethovenin syntymän 250-vuotispäivän kunniaksi julkaistu Ortofon 2M Black LVB 250 Exclusive Model -äänirasia. Ortofonin 2M Black -lippulaiva on yleisesti tunnustettu yhdeksi markkinoiden parhaista MM äänirasioista, mutta Ortofonilla paras ei tarkoita sitä, etteikö sitä voi parantaa. Ortofon 2M Black LVB on valittu EISA Phono Cartridge 2021-2022 tuotteeksi.
EISA 2021-2022:
"Ortofonin pitkään tuotannossa olleen 2M-mm-äänirasian viimeisin versio kunnioittaa Beethovenia 250 vuotta hänen syntymänsä jälkeen, mistä merkkinä on säveltäjän kuva rasian kyljessä. Tarjolla on silkkisen hienostunutta ääntä, joka sopii erityisesti klassisen, jazzin ja akustisen musiikin kuunteluun. Jalostuneen rauhallisessa rasiassa käytetään samaa neulaa ja neulavartta kuin valmistajan Cadenza Black -mc-mallissa. Tämä yhdessä uuden jousituksen kanssa mahdollistaa tarkan äänen täsmällisellä stereokuvalla sekä jousien ja muiden akustisten instrumenttien kaipaamalla pehmeällä rehevyydellä."
Benefits of high-end materials
The 2M Black LVB 250 has been recreated from the concepts of its predecessor, the 2M Black, but the 2M Black LVB 250 performance takes one step further to enhance the cartridge’s capabilities and technical excellence.
The 2M Black LVB 250 uses a Nude Shibata diamond on a Boron cantilever, the combination known from the acclaimed MC Cadenza Black cartridge.
The Nude Shibata stylus’s slim, highly polished profile allows an exceedingly wide contact area to the groove walls and ensures notably detailed reproduction throughout the spectrum, including even the highest frequencies.
The use of an extremely stiff and lightweight Boron cantilever adds remarkable transparency, speed and responsiveness.
The new rubber compound formula
To attain an optimal interaction between compliance and damping, a new rubber compound for the suspension system has been developed.
The new rubber compound formula is based on the Multi Wall Carbon Nano Tubes (MWCNT) highly efficient nano filler. The new MWCNT-based compound offers desirable mechanical properties, which ensure better damping and improve the overall performance of the cartridge.
Also, the new MWCNT rubber compound allows for more environmental-friendly production, adding further benefit. The MWCNT powder is applied in a rubber polymer matrix and not in a powdered form, which makes the production process more clean, non-polluting and energy saving.

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
