Foundation PH9

New! Phono Preamplifier

The PH9 phono preamplifier is a great pairing with most cartridge and turntable combinations. A trio of 6H30 vacuum tubes are 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.
