John Curl Design
For systems built around premium loudspeakers and serious front-end components, this is the kind of amplifier engineered to remain composed, spacious, and effortlessly dynamic even at very high drive levels.
Technology & Design
Ultra-high-bias Class A/AB topology — the JC 1+ is engineered to preserve the sweetness and liquidity associated with Class A while retaining the power and efficiency advantages of Class AB when the music demands more.
Serious power supply architecture — a 2.1 kVA shielded toroid transformer, six 33,000uF Nichicon Gold Tune filter capacitors for the output stage, and a separate 22,400uF input-stage supply all contribute to the amplifier’s tremendous grip and composure.
High-speed, high-current output stage — 24 beta-matched bipolar output transistors, a MOSFET driver stage, JFET input stage, and peak current capability of 180 amps give the amplifier the ability to react instantly and cleanly to demanding transients.
Refinement-enhancing details — Bybee Music Rails™, direct-coupled signal paths, DC servo and relay protection circuits, hyper-fast soft-recovery bridge diode rectifiers, and premium parts throughout all support the amplifier’s reference ambitions.
In a carefully assembled system, the JC 1+ is built to deliver huge dynamic swings, deep bass authority, and the sort of dimensional realism that defines statement-level amplification.
FAQ — JC 1+
Is this amplifier sold individually or as a pair?
This listing is for one monoblock amplifier, sold each.
How much power does it deliver?
It is rated at 450 watts into 8 ohms, 850 watts into 4 ohms, and 1,300 watts into 2 ohms.
Does it really operate in Class A?
Yes. With the bias set to high, the first 25 watts operate in pure Class A. With low bias selected, the first 10 watts operate in pure Class A.
Can I use balanced connections?
Yes. It includes Neutrik locking XLR balanced input and loop output jacks, along with RCA input and loop output jacks.
Who is this amplifier best for?
It is best suited to high-end stereo or theater systems using premium loudspeakers that benefit from extreme current capability, control, and headroom.
