Ortofon Kontrapunkt a
Kontrapunkt a has an aluminum cantilever is mounted with a super polished nude fine line stylus. Coils are made from 6-Nines pure silver wire, and the output is as high as 450 µ Volt at 5 cm/sec. by 1 kHz.
The sound picture of Kontrapunkt a MC cartridge is more relaxed, homogeneous and moderate dynamic in the perspective compared to the Kontrapunkt b and with great space and depth in the stereo image.
Depending on the equipment, room and music programmer resistive loads on 100 Ohm or much higher can influence perception of details.
The cartridge seems to work well in combination with various rooms and loudspeakers.
