The PH 150 is a phono preamplifier from ModWright Instruments, an American manufacturer known for combining tube-influenced circuit design with considered engineering. The PH 150 brings that approach specifically to phono amplification with substantial gain for both cartridge types.
Key specs that matter
Gain is a substantial 72dB for MC cartridges or 57dB for MM designs - high figures ensuring even the lowest-output moving-coil cartridges are amplified to a fully usable level without requiring an additional step-up device.
Sound and use context
Expect the engaging, tube-influenced tonal character ModWright's broader design philosophy is known for, extended specifically to phono amplification with substantial gain covering even the most demanding low-output cartridges.
Pairing
The substantial 72dB MC gain figure means even low-output moving-coil cartridges are covered directly without needing a separate step-up transformer, simplifying system assembly.
Alternatives
ModWright Instruments' broader amplifier catalogue, including the KWH 225i integrated amplifier, offers natural companion components for buyers building a coherently voiced, entirely ModWright-based analogue and amplification system.
