Two-Channel Power with Elegance and Precision
The Parasound A23+ brings studio-level amplification into your listening room—delivering clarity, depth, and control that defies its compact size.
Co‑designed by legendary engineer John Curl, it features a dual-mono Class A/AB architecture with independent transformers per channel. With 160 W per channel into 8 Ω (240 W into 4 Ω) and bridgeable to 500 W, along with balanced XLR and gold-plated RCA inputs, the A23+ integrates seamlessly into stereo or home theater systems.
Praised by reviewers:
- SoundStage! – “Parasound provides great value… I haven’t heard better sound or seen higher build quality at this price. An impressive power amplifier.”
- Home Theater Hi-Fi – “Solidly constructed and good‑looking amplifier… Balanced sonic characteristics with good presentation of musical details.”
- The Audio Tailor – Highlights “transparency from a sonorous 5 Hz sub-bass right through to 100 kHz,” pointing to exceptional clarity and signal purity.
