Graham Slee Gram Amp 2 Communicator Phono Stage

Graham Slee Gram Amp 2 Communicator Phono Pre Amplifier 

A top notch turntable phono pre amplifier in a little "aluminium box" is Graham Slee's way of making affordable the best sounding budget to mid-market turntable phono pre amplifier you can buy.

Originally one in a range of four Gram Amps, the lesser Gram Amp 1 was dropped and now every turntable phono pre amplifier they make delivers more sound to the pound, dollar or euro than any other make.

The description "aluminium box" is a little unkind – it is in fact a lightweight black-anodised aluminium case.
