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.

The Parasound P 6 and Parasound A 23+ play together in a pleasingly balanced and precise manner, while still musical with tonality that tends toward warmth. The consistently very supple reproduction and simultaneously true-to-size presentation and pin-point positioning of individual instruments and voices is amazing. Yes, this is how HiFi is fun.
LowBeats (Germany) November 2020
There is a lot to like in the reasonably-priced Parasound HALO A 23+ stereo amplifier. It is stylish, packs sufficient amplification power, and delivers solid high-fidelity sonic performance.
Secrets of Home Theater & High Fidelity, November 2020
One strength is its capability to reproduce a wide sonic palette, with depth and plenty of micro information. Parasound's power amp is able to bring out the best bass from speakers. Different kinds of music made us appreciate the unusual character of this amplification. Outstanding!

Parasound provides great value in the Halo A 23+. I haven't heard better sound or seen higher build quality at this price. An impressive power amplifier.
Soundstage Network July 2019 Reviewer's Choice
Together, the Parasound P 6 and A 23+ are dynamite. Pure sonic magic with brilliant dynamics, delicious midrange and impressive resolution. To get such good sound for the price of this duo seems almost unnatural. One incredibly appealing preamp-amplifier package from Parasound.
