The PH 9.0 is a phono preamplifier from ModWright Instruments, an American manufacturer known for considered tube-informed electronics engineering, built with comprehensive six-step MC impedance adjustment. The PH 9.0 brings ModWright's considered engineering to a versatile phono format.
Key specs that matter
Two single-ended inputs are provided. MC current-sensing input impedance offers a comprehensive six steps - 10, 20, 50, 100, 250 or 470 ohms - while MM input impedance is the standard 47,000 ohms. Gain is a substantial 64dB for MC or 52dB for MM. Frequency response spans a wide 20Hz to 50,000Hz within plus-or-minus 3dB. At 254 x 254 x 101.6mm, the PH 9.0 maintains a manageable phono preamplifier chassis.
Sound and use context
Expect clean, accurate RIAA equalisation reflecting ModWright's broader considered engineering approach, combined with comprehensive six-step impedance adjustment covering virtually any moving-coil cartridge.
Pairing
The six-step impedance adjustment lets a listener precisely match this phono stage to virtually any moving-coil cartridge without compromise, and ModWright's own LS 99 or LS300 preamplifiers offer natural, brand-coherent pairings.
Alternatives
ModWright's broader electronics catalogue offers alternatives for buyers wanting a different configuration.
