The Gram Amp 2 was designed to give above-average performance in a budget to ‘mid-fi’ system. In a better system it ‘punches above its weight’ and produces a stereo image with width and depth beyond the speakers. This great little phono preamp is purposely made small, lightweight and unobtrusive . Its #16 gauge black anodised aluminium case with silvered lettering looks good in any setting, but most of all it makes it possible for this high performance UK made phono preamp to be offered at a competitive price!
