Audio-Technica ART-1000 designer was inspired not by Neumann, they are inspired by Japanese design invented in the 70’s by VICTOR for Direct Coupled cartridges such as MC-1
It’s accuracy and reliability are extremely high, while unit per unit variations are minimised. The weight is almost a one hundredth that of conventional coils. Employment of a coreless coil eliminates the possibility of magnetostrition. The magnetic circuit is constructed of a samarium cobalt magnet and an iron cobalt yoke in the vertical configuration for obtaining an excellent magnetic efficiency so that the merit of the direct-coupled construction can be fully utilised. Shibata (0.1mm square diamond) on Beryllium cantilever, output 0.2mV, frequency response from 10Hz to 50000Hz. Hard to find in working condition nowadays, an old printed coil is fragile. I’ve bought 3 samples and only 1 of them is working! (I asked Peter Ledermann and he said it can be impossible to fix the coil, but he could check).
Victor developed this techniques further in the 80’s with next models such as MC-10 and MC-L1000
If i remember correct when M.Fremer visited Audio-Technica in Japan they said they are inspired by Victor design.
The notable one, to me, is Audiotechnica’s ART 1000 cartridge which attaches very tiny coils to the tip end of the cartridge (just behind the stylus). As far as I know, this is a unique design.
