Serving as the flagship model among Grado's Prestige Series phono cartridges, this high-output transducer pairs an aluminium cantilever with an elliptical diamond stylus to extract micro-detail and dynamic nuance from record grooves. With its 4.0 mV output and standard 47k ohm loading compatibility, it integrates directly into moving magnet phono stages across a diverse selection of high-fidelity turntables.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eThe Hi-Fi Centre Team Take\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eLiving with the Grado Gold 4 brings a distinctly organic warmth and cohesive flow to long evening listening sessions, effortlessly subduing surface harshness while preserving the natural body of acoustic instruments.
