Graham Slee Gram Amp 2 Special Edition MM Phono Stage


SKU: N/A Categories: ,


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

Since then its design – both in audio performance and appearance – has been refined a number of times.

For such a low-cost, small and lightweight phono preamp, it has proved itself capable of delivering a blistering musical rendition.
