Graham Slee – Gram Amp 2 Special Edition Phono PreAmp

The Gram Amp 2 Special Edition phono preamp won’t stamp any “signature” on your music so you’ll be able to hear all the qualities of your cartridge.

Supplied with a basic (“green energy”) power supply with self-adjusting voltage, and with power-pins fitted to suit your power outlet — you can upgrade by swapping over to PSU1 power as and when you’re ready.
