I am going to offer 'Audionix', a Japanese company that had some relationship with Ortofon.
A number of their products were labelled ADN - (model number).
Information is very limited & sketchy.
Internet references (including recent ebay auctions ..............) may offer 'Audionic(s)' or 'Audionics of Oregon', and may describe a similar Ortofon relationship (e.g, importer, maybe technical, etc.)
However, Audionix definitely had ADN part numbers + Ortofon relationship, and may have stuck a sticker on your cartridge prior to sale.
I came across Audionix when researching a SUT prior to purchase ......
Information sketchy, but apparently a 1980's SUT for low-impendance cartridges, such as Ortofon SPU.
I found this reference, translated from Japanese (perhaps that is where the Audionics comes from ...):
Audionics was the distributor for Ortofon until the late 1970s . Although Harman International took over as Ortofon's distributor at the end of the 1970s, Audionics did not completely withdraw from the analog market. Their new product was a step-up transformer for MC cartridges. Along with their first product, the ADN-III head amplifier, they released a kit using the TH7559 transformer from Partridge, a prestigious British transformer manufacturer. Later, they began selling finished products using Partridge transformers. In the early 1990s, they also handled finished products from Partridge itself. However, the brand seems to have disappeared around 1993-1995. The first head amplifier/step-up transformer, the ADN-III, was released in 1977.
So I can get Audionix to Ortofon & ADN. No ADN logo, but similar typeface (see above) on some of their later products.
Hope this is helpful!

Thanks, very helpful. The vendor named Audionics in the ad but no further information. All searches for them turned up only information from the American outfit. I expect you are correct and the sticker is just a distributor label rather than an indication of some difference from the non-labelled version of the cartridge.
