I recently compared my Grand Master to my previous setup Ortofon MA 90 and Tom Evans Groove+ SRX. The Grand Master sounds remarkably natural, at least to my ears, but with the amazingly black background. The unit has operated flawlessly. The EMM DS-EQ1 works superbly, is superbly built, relatively small footprint and not unreasonable in price but again just my two cents. The combination has renewed my interest in Vinyl remarkably.
