Gram Amp 2 Special Edition RIAA Preamp
An amazing little RIAA preamp for moving magnet, high output moving coil and moving iron phono cartridges. It's quite a gem as you'll find!
The Gram Amp 2 Special Edition RIAA preamp was first launched in 2001 with a number of improvements over the legendary budget Gram Amp 2 "Communicator". The Special Edition features 50 percent more gain to deliver a higher output which is a closer match to digital sources.
Originally built as an entry-level RIAA preamp for the USA market, It's earned itself several recommendations with the American Hi-Fi press.
As of September 2012 "V3" sports our own slimline extruded enclosure with our usual classic clean line styling.
