Elevate Your Home Audio Experience to True Audiophile Standards
Unleash the full potential of your sound system with this finished HiFi tube preamplifier. Built around the famous Hetian Mao SRPP circuit, an upgraded design based on the classic Marantz 7 preamp, this unit is made for music lovers who long for natural, silky analog tone. It acts as an essential link between your audio sources and power amplifiers, injecting richer harmonic depth, delicate musical emotion and immersive spatial imaging into every track you play.
The Hetian Mao circuit optimizes the weakness of the traditional Marantz 7 topology. It replaces the conventional cathode output with an SRPP buffer stage. The SRPP output stage works only as a buffer without voltage gain, offering much stronger load-driving capability. It retains the beloved sweet midrange signature of Marantz 7, while delivering improved resolution and extended high/low frequency response alongside an excellent signal-to-noise ratio.
