Because music is mostly transients.
Our 282-e cartridge.
From the attack of an organ note to the bite of a plucked string, music is mostly transients: sudden bursts of sound at all frequencies.
On a stereo record, transient signals define the characteristic attack and decay of musical sounds, differentiating one instrument from another.
Until Micro-Acoustics' direct-coupled design (U.S. Pat. No. 3952171), all high-fidelity cartridges concentrated on tracking ability: maintaining contact between stylus and groove at low forces, for minimum record/stylus wear. This reduces transient ability, because under-damped moving assemblies tend to remain in motion, impairing clarity and definition. On the other hand, earlier cartridges with stiffer stylus assemblies had better transient ability, but greater wear.
Unlike these single-pivot cartridges, which maximize one ability, Micro-Acoustics' 282-e has twin pivots optimized for both abilities.
Resulting in superior transient and tracking performance from one cartridge on al' records, including warped discs. Performance totally independent of tonearm cable capacity or preamp input impedance.
