Gustard P26 Preamplifier
Join the Waitlist to be notified of launch!
The Gustard P26 Preamplifier comes in a Class A fully balanced design with the left and right channels divided into regions to create a good separation between the two. It has a native fully balanced architecture that requires no conversion from input going to volume control and even to the amplifier circuit.
The P26 comes equipped with two in-line OP Amps so that DIYers can replace them to play with the sound. It also has a discrete hybrid architecture that ensures circuit consistency. Finally, it also includes a diamond-shaped differential output stage, adjustable input/output stage gain, consistent and unbiased volume, and a customized 50W dedicated toroidal transformer. Apos Audio's research team found measurements done by Audio Science Review for the P26 here.
