Audio Research - PH9 Phono Stage
(In-Store Only) Contact for Product Availability.
Description:
The PH9 phono preamplifier is a great pairing with most cartridge and turntable combinations. A trio of 6H30 vacuum tubes is at the core of a simple and clear signal path to provide the most transparent preamplification possible. 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. The Foundation Series continues this passion and philosophy, offering the listener stunning playback, great value, and unparalleled long-term support.
