Audio Research - GSPre Préamplificateur
The GSPre is the nerve center of a system – not only directing signals and providing attenuation, but also interpreting and deciphering complex signals to create a musical story with the drama and intrigue befitting your favorite songs.
The GSPre is the nerve center of a system – not only directing signals and providing attenuation, but also interpreting and deciphering complex signals to create a musical story with the drama and intrigue befitting your favorite songs. The job of a preamplifier is to do its work discretely, leaving the musical signal with as little signature as possible yet still unraveling the chapters that comprise the lyrical narratives of the source material. With decades of expertise creating some of the finest preamplifiers ever produced, the GSPre is certain to continue the legacy on which Audio Research has built its reputation.
