PD-171 has been a highly regarded analog player in the market due to its ability to convey the sense of musical depth and feeling of vinyl records. There are two new revisions, an armless type, the PD-171AL, and the PD-171A, with a universal tone arm, adjustable to the users' requirements and systems. At the heart of these models are a newly developed, high output power supply circuit and an AC synchronous motor. We have incorporated ideas developed for our audio amplifiers and have adopted a belt drive system which rotates high inertia, heavyweight turntable. A high-quality hairline finished aluminum upper surface blends beautifully with the wooden base cabinet to conceal the robust and accurate machinery within, developing a warmer and softer personality with whom the listener may spend many hours of enjoyment, expressing the true personality of analog recordings.
