GSP Gram Amp 2 Communicator Phono Stage

It may look cheap and plain but this little phono preamp is legendary for its audio performance! The Gram Amp 2 Communicator phono preamp is THE phono preamp that first made the GSP name synonymous with superior vinyl reproduction and incredible sound staging!

Overview

"What I didn't expect was for it to soundstage like a four-figure pre"

Geoff Husband, TNT Audio

A four-figure pre? Yes, Geoff Husband with his unbiased ears told the audio world the truth! Since then all I've done is swap the packaging - the phono preamp now in a black anodized metal case with silver anodized print instead of the old plastic project box, and the printed circuit board inside is larger. Even 11 years after I sat down at my kitchen table with a notepad, calculator and a handful of parts the Gram Amp 2 phono preamp still packs a performance few others can match at up to ten times its price!

"Switch to the power rock of Led Zeppelin II and the Gram Amp 2 delivers both crashing cymbals and deep thundering bass with ease"

What Hi-Fi? Sound and Vision

The vinyl DJ will love this little phono preamp too: I used to DJ and know quality sound starts at the phono preamp - after all you want every gig to be a good gig! The Gram Amp 2 Communicator phono preamp has another great attribute - it doesn't emphasise clicks and pops - you could say click and pop reduction is an inherent part of its design. Partner this phono preamp with a good cartridge such as the Stanton 890 and a substantial professional deck like the Technics SL1200 series and you'll have the best sound around! And by the best we mean broadcast quality!

"It concedes little indeed to more expensive designs and kept us entertained for hours. Timing is first-rate, instrumental timbre convincing and detail resolution frankly impressive..."

Compatibility

The Gram Amp 2 Communicator phono preamp will give an output of 400mV with a medium sensitivity moving magnet cartridge (4.5 to 5mV). Gain is X84 (38.5dB).

Intentionally, its gain is slightly on the low side which makes it most suited for use with medium to high output moving magnet cartridges. This also makes it an ideal phono preamp for the DJ whose disco records can give a much higher output - its lower gain means there's less chance of clipping (overload) so higher volumes can be achieved with reduced speaker wear.
