Audio Research GSi75 integrated amp


A preamplifier, amplifier, phono stage, and digital to analogue converter all in one chassis, the GSi75 is the latest addition to Audio Research’s stylish G series. Powered with the new KT150 output tube, the GSi75 is said to “supply finesse and control that belies the 75-watt per channel power rating”. The digital-to-analogue converter will handle almost any sampling frequency including DSD. The phono stage and headphone amplifier round out the GSi75, providing total system control and integration. The elegant, understated industrial design will complement the rest of your system both visually and sonically. The Audio Research GSi75 integrated valve amplifier is available now, priced at £14,500.
