Parasound Halo JC1+ Monoblock Power Amplifier (Each)
JC1+ – Monoblock Amplifier, 1 x 450watt, 8 ohm (Black or Silver Finish)
The Parasound JC1+ delivers monoblock performance on a majestic scale—450 W into 8 Ω, over 1,300 W into 2 Ω, and up to 25 W in pure Class A. Whether it’s the intimate tones of solo piano or the thunder of orchestral crescendos, the JC1+ delivers every detail with uncanny control, space, and realism. Built on John Curl’s decades-long halo legacy, this amp raises the bar with rugged R-core power supply design, system tuning switches, and precision-grade audio components. Its transparent performance and refined execution make it ideal for high-resolution systems, audiophile-level home theaters, and demanding speaker pairings alike. 400 -> 450 Watts @ 8Ω, 800 -> 850 Watts @ 4Ω, 1200 -> 1300 Watts @ 2Ω, Filter capacitance: 132,000 -> 198,000 uF, Transformer capacity: 1.9 -> 2.1kVA, Output transistors: 18 -> 24 Sanken 60Mz devices.
