what is the proper loading


for cartridge specs that read;
# Output voltage at 1000 Hz, 5cm/sec.: 300 µV
# Channel balance at 1 kHz: < 1 dB
# Channel separation at 1 kHz: > 20 dB
# Channel separation at 15 kHz: > 10 dB
# Frequency range: 20-25.000 Hz
# Frequency response: 20-20.000 Hz + 2 / - 1 dB
# FIM distortion at recommended tracking force, DIN 45.542: < 1%
# Tracking ability at 315Hz at recommended tracking force: > 70 µm
# Compliance, dynamic, lateral: 8 µm/mN
# Stylus type: Nude elliptical
# Stylus tip radius: r/R 8/18 µm
# Equivalent stylus tip mass: 0,45 mg
# Tracking force range: 3,0-5,0 g (30-50 mN)
# Tracking force, recommended: 4,0 g (40 mN)
# Tracking angle: 20°
# Internal impedance, DC resistance: 1.5 Ohm
# Recommended load impedance: > 10 Ohm
# Cartridge body material: Aluminium
# Cartridge color: Silver/Black
# Cartridge weight: 28,5 g

BTW - heavy tracking force doesn't really "eat" records .... rather very low tracking force in conjunction with high skating.
The correct loading with vary with your interconnect cable and how sensitive your phono section is to RF. If it does not care about Radio Frequency energy at its input, you will find that loading does not make much of a difference.

The loading only affects the circuit at RF frequencies, and the correct load will dampen the RF oscillation that can be associated with the coils of the cartridge and the capacitance of the cable, which forms a tuned RF circuit.

This is why loading is critical with some systems and not with others.

Yeah I know....I forgot to think SPU when we are talking that much force. Cheers !
