Gram Amp 2 Communicator
Graham Slee Gram Amp 2 Communicator, now in black.The Gram Amp 2 Communicator phono preamp is a fifth generation product from Graham Slee, and and a definitive upgrade for the much applauded but now discontinued Gram Amp 1 preamp. The new black bodied Gram Amp 2 Communicator has been styled with definite purpose in mind. Its new black case is styled in simple fashion with a led at the front to show its powered, but other than that no other feature. Its a quality item, and as the starter amplifier from graham Slee features the hand built internal build quality that we have all come to expect and respect.

The gram Amp 2 is know for its higher-level dynamic performance and superior timing, timbre and detail resolution provide seamless tonal balance for a musical feast of shimmering highs, fluid midriffs and deepest bass. matched with the right cartridge/arm/turntable combination this little amplifier will show you just how good a starter analogue system can sound like.

For total immersion (in the music) an optional upgrade to the PSU1 power supply unit is available.

". The Gram Amp 2 was something else... Given the lack of the IEC warp filter and other changes, I had expected it to sound a little different. What I didn't expect was for it to soundstage like a four-figure pre."
Geoff Husband - TNT-Audio
