Working our way through vintage vinyl, modern heavy weight pressings, 320kbs mp3’s and even just a YouTube stream, the Radius 4 improved whatever was thrown at it, offering articulate representations of the original which were full of character. To ensure we weren’t getting drawn in under the spell we plugged turntable 2 into another of Andy’s creations, the Xone42 mixer. With 2 copies of the same track we proceeded to flip between the two. It was like switching between night and day. Low end was fuller, the mid more textured, and the highs sang with the clarity of crystal.
