Phono cartridges operate at very low signal levels, which makes them highly susceptible to interference from ground loops, Radio Frequency Interference (RFI), and Electromagnetic Interference (EMI). If a system isn't well-shielded or properly isolated, it might be more vulnerable to these disturbances. Therefore, Skoll owners whose audio setups incorporate robust shielding and isolation (whether intentional or not) are likely to avoid such issues, explaining why some users do not report the buzzing noise. Additionally, it's worth considering that some people might not be as bothered by or even notice this noise, and thus might not report it.
