Drop the JC5 into your system and the room changes. Bass hits deeper without bloat, vocals float free of the speakers, and big crescendos stay calm and composed—power with finesse that makes everything feel more alive. Designed by John Curl, the JC5 focuses on what matters: high-bias Class A/AB with the first 12 W in pure Class A, 400 W x2 into 8 O (600 W x2 into 4 O), a 1.7 kVA toroidal transformer with 132,000 µF of storage, and 90 A peak current with safe handling of 1.5-O impedance dips.Read More
