Setup context
Use this cartridge reference with the Tonearm Match Lab to estimate cartridge-tonearm resonance. The key setup inputs are body mass, tracking force and 10 Hz compliance.
Reference data is best-effort and should be checked against manufacturer documentation before critical setup decisions.

Model-specific matching analysis
Its 6.5 g body mass is included in every total moving-mass estimate below. The calculation uses 10.2 CU at 10 Hz; this value dominates how strongly resonance shifts with tonearm mass. The stored tracking-force reference is 1.8 g. The database classifies this cartridge as Moving Iron. The reviewed source data identifies the stylus as Elliptical. Nominal output in the reviewed record is 4.5 mV. Stored load-capacitance guidance is 150–200 pF.
| Tonearm effective mass | Estimated total mass | Calculated resonance | Interpretation |
|---|---|---|---|
| 6 g tonearm | 13 g | 13.82 Hz | above the usual 8–12 Hz setup window |
| 10 g tonearm | 17 g | 12.09 Hz | above the usual 8–12 Hz setup window |
| 14 g tonearm | 21 g | 10.87 Hz | inside the usual 8–12 Hz setup window |
| 20 g tonearm | 27 g | 9.59 Hz | inside the usual 8–12 Hz setup window |
| 25 g tonearm | 32 g | 8.81 Hz | inside the usual 8–12 Hz setup window |
Calculation: f = 1000 / (2π√(M×C)), using cartridge mass, 0.5 g fasteners and the stated 10 Hz compliance. This is a setup estimate, not a laboratory measurement.
