In recent years, more and more audiophiles enjoy playing vinyl records as well. One of thereasons for this development is the fact that amplifier performance nowadays isincomparably better than in the heyday of analog records, allowing a re-evaluation of theplayback qualities of this medium. The Accuphase lineup has continued to feature bothstand-alone and plug-in type phono equalizer amplifiers which we were actively developing
and perfecting, to create the ideal record playback environment for all users.
On the other hand, the phono cartridges that extract the musical information from the record
groove also have a vital role to play. Accuphase has a long history in this area as well,
beginning with the AC-1 introduced in 1979. This was followed by the AC-2, AC-3, and AC-5
models which all received high praise from discerning experts. The fifth generation is now
making its debut with the AC-6 that fuses our accumulated experience with latest technology
advancements, designed for ultimate playback capability. A combination of materials
selected according to strict criteria ensures that even the most minute vibrations engraved in
the record groove are faithfully picked up and reproduced with stunning musical results.

Faithfully tracing the analog record groove
This MC cartridge elevates the art of sound creation to another dimensionThe AC-6 is a new addition to the highly acclaimed Accuphase lineup of phono cartridges. This MC
cartridge features latest technology in terms of materials and construction. The semi line contact stylus
extracts minute vibrations that are transmitted instantaneously to the magnetic circuit by the boron
cantilever with high propagation speed. The magnetic circuit is mounted on a strong titanium base,ensuring accurate conversion into a music signal. Every single aspect of the cartridge has been finely
honed to deliver optimum performance, ushering the listener into the wonderful world of analog records.

extruded titanium further hardened by gold ion plating. This provides afirm hold for the magnetic circuit and the vibration transmitting section
while keeping internal losses to a minimum. Titanium is a difficult
material to machine, but its light weight combined with high stiffness
and corrosion resistance made it the ideal choice for the AC-6. The
cartridge body of extruded aluminum has been given an elegant
gold-colored alumite coating, making it a great looking match for any
high-quality turntable.
