The Graham Slee Gram Amp 2 Communicator is the original Graham Slee phono pre-amp that kicked off rave reviews and sales success over 11 years ago. Since then it has evolved and improved both in performance and looks and represents a superb entry level moving magnet phono pre-amplifier.
Ideal for those customers whose amp does not feature a turntable input, housed in a smart black metal case with outboard power supply for reduced hum and noise.
The circuit inside has been designed with one goal in mind - out right best sound quality for the money. All unnecessary items have been omitted in the search for superb sound.
The input sensitivity of 4.5mV makes it ideally suited for medium to high output moving magnet cartridges, and it's amplification factor of x84 means you can plug the output directly into a spare line input on your amp.
Coming with a universal power supply as standard, you could also upgrade Graham Slee Gram Amp 2 Communicator at a later date by adding the Graham Slee PSU1 regulated power supply, see related products below.
