نظرة عامة

PH9 provides class leading phono preamplification for the majority of cartridge and turntable combinations.

A trio of 6H30 vacuum tubes form the core of a simple and clear signal path. A classic Audio Research design, the PH9 revels in the vibrance and vitality with which tube gear excels, yet neutrally portrays the subtlest shadings in cartridge and tone-arm selections with transparency.

عن Audio Research

When Audio Research was founded in 1970 by Bill Johnson, he had one goal in mind: to advance the state-of-the-art in music reproduction. Today, Audio Research remains true to its roots as a performance-oriented company driven by proven philosophies and superior design. Many industry observers consider Audio Research one of the true originators of the concept of “high-end” audio, offering an unsurpassed level of performance that can easily be heard and appreciated by all. Over its first half-century, Audio Research has grown from a small operation in the back of Bill’s shop to a modern, self-contained factory with dedicated R&D, testing, manufacturing, quality control, and listening facilities. Manufacturing is done by hand in-house, from the ground up, in our Minnesota facility. (Contact us for a tour if you are near Minneapolis, it’s fascinating to meet the people and see the process in action.) 330M Monoblocks Launched May 2024

Five impedance settings
Five different impedance settings allow for cartridge loading, which can be changed on the fly with the included metal remote. Cartridge impedance, tube hours, auto shutdown, and other features are included in the menu system. Since 1970, High Definition has been more than our trademark; it has been our guiding principle for all products. PH9 continues this passion and philosophy, offering the listener stunning playback, great value, and unparalleled long-term support.
