Just thought I'd mention how wonderful the very recently purchased Graham Slee Gram Amp 1 makes my vinyl sound. My previous stage, the Project Phono Box, was functional and great value but the Gram Amp 1, is indeed, as their PR claims, a bridge to more sound. And what a sound. Fuller, deeper, warmer . . .the usual litany of superlatives, but true. My ears have heard the glory of the sacred wonder kind, to paraphrase Morrissey paraphrasing someone else. Thanks Gregory for your advice regarding my cartridge. Still not sure of the exact model but it seems to be a moving magnet and is doing a fine job of unleashing the music locked into those troublesome grooves.
