It’s all about … the smaller the signal, the more that resonance behavior plays an important role! The more we talk about the mechanical/electrical transducer, the clearer it becomes that the choice of material and its resonance characteristics are audible. The cartridge and all that comprise it are the most sensitive parts of an audio reproduction chain. Here is the transfer of the mechanical modulation into an electrical signal, and here is the signal the weakest!!!
Wood has always been one of the most-used materials in audio. Yet various woods, as well as MDF, have specific structures and densities, and therefore possess their own characteristic “sound”.
