German magazine HiFi Test (Issue 4/2025) has published a highly positive review of our Edwards Audio MM4 MK2 moving-magnet phono preamplifier, conferring a Class rating of “Top Class 1.0” alongside a “Very good” price/performance verdict. Reviewer Alexander Rose-Fehling highlights the MM4 MK2’s engaging presentation and build quality, noting that it “really makes music – with drive, pace and air.”
Refined design, serious engineering
The new MM4 MK2 moves to a folded steel chassis (replacing the earlier acrylic case) while retaining an elaborate internal linear power supply with a toroidal transformer and separate positive/negative rails. The circuit employs tight-tolerance Vishay MELF resistors, Panasonic FM electrolytics, and Vishay film capacitors – uncommon attention to parts quality at this price. SRP: €599.
