PH-1 Phono Amp

Grado PH-1 Phono Stage


Grado's New Proprietary Phono Equalization is "The Best of Both Worlds."

Our new Grado Phono Preamp, model PH-1, represents the most successful solution to one of the most complex technical challenges in the field of audio that Grado Labs has ever tackled. It can be compared to the undertaking of designing our highly acclaimed phono cartridges, headphones and our world renowned RA-1 headphone amplifier over the past several years.

Our design goals were for a truly superb sounding phono preamp to work equally well with both low and high output cartridges with negligible noise.
