Graham Slee Gram Amp 2 SE Phono Stage

Graham Slee Gram Amp 2 SE Phono Stage

The Gram Amp 2 Special Edition phono stage preamp was first launched in 2001 with a number of improvements over its legendary stable mate, the Gram Amp 2 (now called the Communicator).

The Special Edition of the Gram Amp 2 phono stage preamp features 50 percent more gain to deliver a higher output favoured by owners of passive preamps when using medium to high output (4.5mV or above) moving magnet phono cartridges. However, it can be used with all moving magnet, moving iron and high output moving coil cartridges.
