PS Audio GCPH Phono Pre

The GCPH is a high-end standalone phono preamplifier, designed for the highest quality phono
reproduction possible. It is based on PS Audio’s unique Gain Cell Technology and over 30 years
of designing state-of-the-art phono stages. PS Audio built its first phono stage in 1973 and has
been responsible for some of the most loved vinyl amplification electronics the Audio world has ever
known.
The GCPH is built around the same design philosophy all PS phono preamplifiers have enjoyed over
the last 30 years: a passive RIAA curve. The RIAA curve is a specification for the correct playback of
vinyl records, established by the Recording Industry Association of America (RIAA). The purpose of the
equalization curve is to permit greater playback times, improve sound quality, and to limit the physical
extremes that would otherwise arise from recording analog records without such equalization.
