John Curl Design
This amplifier is especially appealing for stereo and home theater systems that need real current delivery, premium build quality, and the flexibility of both balanced and RCA inputs.
Highlights & Benefits
-
Serious real-world power — delivers 160 watts per channel into 8 ohms and 240 watts per channel into 4 ohms, with enough current capability to stay composed under demanding speaker loads.
-
Bridgeable mono flexibility — can be bridged to 500 watts into 8 ohms when greater single-channel output is needed.
-
John Curl circuit design — reflects Parasound’s long-standing emphasis on musically natural, low-distortion amplifier engineering.
-
High bias Class A/AB operation — the first watts run with greater Class A influence before transitioning into powerful Class AB operation for headroom and control.
-
System-friendly connectivity — balanced XLR inputs, gold-plated RCA inputs, loop outputs, and 12V trigger support make integration straightforward.
-
Compact premium amplifier — the Parasound HALO A23+ Power Amplifier in Silver offers genuine audiophile-grade performance without the bulk of a much larger chassis.
Technology & Design
Dual-mono layout and power supply strategy — Parasound uses a dual-mono architecture with independent channel power resources to improve imaging stability, separation, and overall control.
High-current output stage — with 45 amperes peak current per channel and stable operation into difficult speaker loads, the amplifier is engineered to maintain authority where smaller designs can begin to sound strained.
Balanced and unbalanced signal flexibility — discrete balanced input circuitry, gold-plated RCA connections, and loop outputs help the amplifier integrate easily into dedicated stereo or mixed-use theater systems.
In a carefully matched system, the Parasound HALO A23+ Power Amplifier in Silver delivers the kind of composure, grip, and musical transparency that make it a standout value in premium two-channel amplification.
