How to mount your cartridge
of choice for best performance
Here are just some standard recommendations:
For mounting your cartridge, please use
NON- magnetic
M2.5 screws and plastic
washers under the screws head. We recommend
using Titanium screws.
If you can’t use Titanium screws, please use
brass/gun metal M2.5 screws. They are non-
magnetic and provide good energy transfer.
Aluminum is too soft and does not give enough
coupling for perfect energy transfer.
Stainless steel screws always have a minimum
of magnetism - do not use them. You will loose
sound quality.
Do use, if possible, a torque driver with
precisely adjustable settings.
For M2.5 cartridge screws please use torque
settings according to 80-90% of maximum as
recommended by German engineering norm for
DIN 912.
This ensures perfect energy transfer - and
thus gives you the most dynamic and detailed,
uncolored sound from your cartridge.
Detailed recommendations regarding mounting
screws, settings and special tools are available
from acoustical-systems upon your request.
Recommended torque values for
cartridge mounting screws for
optimum energy transfer
M2.5 torque
Titanium
0.75 Nm = 75 cNm
Stainless steel 0.58 Nm = 58 cNm
Brass
0.45 Nm = 45 cNm
Aluminium
0.35 Nm = 35 cNm
