The Graham Slee Gram Amp 2 Communicator phono preamplifier is the British manufacturer's loss-leader product. It was designed to deliver high-end performance at a very tight price.
Graham Slee Gram Amp2 Communicator: design
It comes in the form of a small black metal box around ten centimetres square.
The front panel features only the printed logo and an LED indicating that it is switched on. No external or internal setting is available. And there is no need for any, as this product is designed for MM phono cartridges, Moving Iron or high output MC cartridges, which require a gain of around 40 dB, a load of 47 Kohms and a capacitance of around 200 pF. And this phono stage provides all of this as standard!
It is powered externally via a small 24V DC power supply. To improve the sound quality, it can be advantageously replaced, at a later date, by the Graham Slee PSU1 power supply.
Like all the manufacturer's products, it is assembled by hand in the United Kingdom.

FAQ: Everything you need to know before buying the Graham Slee Gram Amp2 Communicator phono preamplifier
Which cartridges is this preamplifier designed for?
It is designed for MM phono cartridges, Moving Iron or high output MC cartridges, which require a gain of around 40 dB, a load of 47 Kohms and a capacitance of around 200 pF, all values it provides as standard.
Are there any settings to adjust?
No. The front panel features only the printed logo and a power LED, and no external or internal setting is provided. This is of no interest here, since the targeted cartridges have standard characteristics: installation is therefore very simple.
Is it upgradable?
Yes. It is powered externally via a small 24V DC power supply that can be advantageously replaced, at a later date, by the Graham Slee PSU1 power supply in order to improve the sound quality. Like all Graham Slee products, it is assembled by hand in the United Kingdom.
How is this phono preamplifier powered, and can its performance be improved?
The Graham Slee Gram Amp2 Communicator is powered externally via a small 24V DC power supply provided as standard with the unit. To improve the sound quality, this power supply can be advantageously replaced, at a later date, by the dedicated Graham Slee PSU1 power supply. The front panel remains minimalist, featuring only the printed function labels and an LED indicating that the unit is switched on. This design simplicity reflects the manufacturer's philosophy, which prefers to focus its budget on component quality rather than on superfluous features.
