Infinity Black Widow ToneArm
Infinity once offered a very high quality tonearm for analogue record players. This was built only very strictly limited, but he could also come up with some delicacies.
The filigree technology of this tonearm is, as typical for Infinity, very well thought-out and extremely precisely manufactured. Sure, with an analogue drive you can't do without it either way. What sets it apart from most other tonearms, however, is the fact that the tonearm tube is made of carbon fiber. This makes the pure carrier extremely light and at the same time extremely stable. A dreamlike template for a perfect tonearm.
The so-called ULM tonearm is guided by a knife bearing. The damping is done by silicone oil. The connection is made in a 5-pin din socket, which is integrated in the tonearm.
