![]() ![]() The best match for ANY cartridge ever made….is simply the very best tonearm you can afford…whatever its Effective Mass…□ This Resonant Frequency has ZERO affect on the sound quality of a particular tonearm/cartridge combination and I have proved it hundreds of times with a dozen different arms and over 40 cartridges. Yet these days….everyone (without exception it seems)…even tonearm and cartridge designers….happily follow the dictum of this Arm/Cartridge MATCH as if it affected sound quality….❓ I have three out of a thousand or so……and have NEVER experienced miss-tracking or hum even on these three…❗️□ So how many badly WARPED record do you possess…❓ For instance if your tonearm/cartridge Resonant Frequency was 18Hz and you had an organ record or one containing synthesised bass going down to 16Hz….your tonearm may miss-track or you MAY develop a hum❓□ This simply insures against the possibility of any ultra low-level frequency information which MAY be on the record, also inducing this same miss-tracking or hum. Keeping the lower limits of your tonearm/cartridge Resonant Frequency to 8Hz simply insures against this possibility.□ The raison d’etre of this Resonant Frequency…is to avoid WARPED records inducing ‘resonance’ into the tonearm….īut doesn’t it have any meaning for NORMAL records…❓Ī badly warped record induces the tonearm to rise and fall rapidly on the ‘sprung’ cantilever of the cartridge.ĭepending on the severity and frequency of this warping….a subsonic frequency between 2-5Hz is induced so if your tonearm/cartridge Resonant Frequency dips into this frequency range….it will begin resonating and thus miss-track and/or induce hum through your system.□ The RECOMMENDED Resonant Frequency of any tonearm/cartridge combination is between 8-12Hz.īut WHY is this the recommended frequency and WHAT does it really mean…? The Resonant Frequency can be calculated using a complex formula relating Tonearm Effective Mass to the cartridge’s Compliance….or it can be simply measured using a Test record of various frequency sweeps. ![]() Over the last 10 years or so…this topic has become not only ubiquitous, but has mutated beyond its definition, to THE guiding principle of matching cartridge to tonearm….❓❗️□ When I began my journey in high-end audio 36 years ago….no-one ever wrote about arm and cartridge matching nor tonearm resonant frequency…? ![]()
