Direct-Drive Turntable (1988)
The PL-90 is made for the purist. Its features are basic - just those needed to improve sound. In essence, the player is designed to extract all the musical information embodied in the microscopic grooves of your records.
There are some good reasons why the PL-90 makes this possible. One is a tone arm made from alumina ceramics; another is the Pioneer DRA (Dynamic Resonance Absorber).
Alumina combines high rigidity and lightness, which makes it a material ideal for the tone arm. But it lacks internal loss; alone it would make the arm prone to resonance, colouring reproduced sound and causing cartridge mistracking. Therefore, we've developed the DRA and fitted it on an alumina tone arm to effectively increase internal loss.
The DRA, in a word, is a complex resonator that cancels out modes of resonance in the tone arm. The combination of the alumina tone arm and the Pioneer DRA lets the cartridge pick up only music from records with accuracy and precision.
The result is clean, natural, and well-defined analogue sound - the kind you'd like to hear over and over.
