In the complicated landscape of audio, many companies put stratospheric price tags on great performance. Our mission couldn't be more different. Simply put, we offer the most performance for the money by finding the sweetest spot between price and diminishing returns. We've all been on the consumer side: music lovers, musicians, and audio enthusiasts looking for top-tier sound without breaking the bank.
Everything we do at Parasound is customer-centric because that's how we define value. Most of our customers don't have trust funds and have to work for their money — so we give them their money's worth and then some. Every time another expert compares our product to equipment that costs three times as much, we have succeeded.

Parasound’s Halo A 23 Amplifier is the ultimate combination of cutting edge technology, superb craftsmanship, and stunning industrial design. With high current Class A/AB amplification, smooth sounding MOSFET drivers, and balanced XLR inputs, this mighty amp will make any speaker sound better than ever before. The A 23 two channel amplifier boasts 125 watts of THX Ultra 2 certified power per channel, and it looks as amazing as it sounds. Whether it’s movies or music, the A 23 will knock your socks off!

As the A23 is based on a John Curl design (akin to the A21, A31 and A51) it boasts the exemplary qualities you'd expect - but at a lower price point than the more prominent A21. The A23 like it's two channel stable-mates can be used to stunning effect with the Parasound range of pre-amplifiers such as the JC3+, P5 or the larger and flexible P7 - perhaps within a multi-channel application. It can of course be used effectively as a 'mono-block' in bridged mono mode as well meaning that you can get a very dexterous 400 watts into an 8ohm load for those of you requiring huge power into larger more challenging loads or larger spaces.

As you would expect the build quality and components used in the A23 are like all of Parasound's range - very high quality. The A23 features both balanced and unbalanced inputs (RCA's are gold plated) with a designated ground lift switch, and these high quality inputs are matched with heavy-duty 24k gold-plated 5-way speaker terminals on the output stage. For those also wanting to tweak their systems to THX certified installations the A23 features adjustable gain pots for up to THX Reference level.

Despite it's impeccable 'HiFi' credentials (as it has like a host of Parasound's amps - been extremely well reviewed) - the A23 also can be mounted via a set of optional rack ears and has a choice of power activation (front panel, auto sensing and 12v) to ensure that for those wanting the best sound in a custom installation, the A23 becomes a mandatory option.

The Parasound Halo A23 is available in black and silver finishes - please specify on order.

Australian Hi-Fi, June 2015
"Parasound is one of the very few companies in the world that has a reputation for state-of­-the-­art sound quality and engineering as well as a reputation for delivering superb value for money, and in looking at this duo, it's easy to see why: buy this pair and you'll be getting an awful lot of power and incredible performance for what, quite frankly, are ridiculously low prices. And that's true no matter whether you buy the P 5, the A 23, or both."

SoundStage, June 2014
"I was surprised by the A 23's clarity, soundstaging, and natural sound. I estimate that the combination of it and Parasound's recently reviewed Halo P 5 preamplifier will result in sound that is unassailable in quality by any other combination of components that can be bought for a like amount. The A 23 sounded surprisingly good from the moment I first turned it on. Several months later, I hated to turn it off for the last time and send it back."

Good Sound, December 2004
"My son began dancing while I played this CD through the Parasound combo (P 3/A 23) - they passed the toe-tapping test with flying colors." "...the Halo A 23 never sounded strained, nor did the sonic picture lose coherence or take on unwanted coloration with the increased volume." "Parasound's Halo P 3 preamplifier and Halo A 23 power amplifier are sexy in appearance, easy to use, and sound solid and satisfying." "Good value and good sound: a winning combination!" - Eric Hetherington

The Absolute Sound, October 2004
Editor's Choice Recommended Product - Power Amplifier under $1,000

Home Cinema Choice (UK), March 2004
"125 Parasound Watts carries a lot more grunt in the real world than a similar number of Watts from most AV amps, as our lab test prove." "...the system is powerful, engaging and very listenable, even when pumping the bass cones as though there was no tomorrow." "Power reserves are high and the whole effect is one of control, good definition and kick ass authority." "...a superb package (C 2, A 52, A 23), whose power and majesty can only be hinted at on the printed page, and tremendous material value for money too. Audition with urgency." 4 1/2 Stars - Alvin Gold

Futurelooks, November 2003
"Each note was reproduced with a distinction, bass extension, and clarity." "The HALO system (P 3/A 23) brought out previously hidden harmonics and details that I never truly heard before, but at the same time, made the track sound a lot more laid back and musical." "Although there are only two speakers attached to this system (P 3/A 23), the three dimensional imaging produced by this system is really outstanding." "Absolutely the best bang for the buck that money can buy." Editor's Choice - Stephen Fung

Stereo (Germany), July 2003
"...darf sich hervorragender Empfangsleistungen rühmen..." - Holger Barske

"...may boast about excellent reception achievements..." - Holger Barske

Stereo Times, April 2003
"This amplifier packs a significant wallop, and does so while maintaining a good measure of soundstage composure and truth of timbre." - Greg Petan, December 2002
"...the soundstage was beautifully overwhelming. I cranked the volume in an inadvertent attempt to involve my neighbors and the A 23 amplifier had no problems keeping up. The soundstage was very full, extending beyond the outside edges of the speakers and left no noticeable holes." "...the sound for stereo music reproduction is better than any A/V receiver I have heard in my system by leaps and bounds." - Brian Kahn

Playboy, December 2002
Playboy's Christmas Gift Guide, featured item: "If you've got it, spend it"

T3 (UK), November 2002 
"From the off it sounds both colorful and convincing." " ...more than capable of generating a generous, cohesive and believable sound that doesn't want for ambient detail or atmosphere. It 'cruises' beautifully too; if amps can sound supple and loose-limbed, these ones do." "...effortlessly musical and consistently enjoyable." - David Vivian

Hi-Fi Choice (UK), November 2002
"'s the Halo style that makes you wonder why other amps at the price aren't this well made." "Beautifully built with even-handed, natural sound. Deep sound stage and bolted-down stereo image." "Looks like high-end electronics, sounds like high-end electronics, priced like mid-fi." - Alan Sircom

The Absolute Sound, November 2002
"...the A 23 made horns sound remarkably lifelike and natural." "...I was impressed with the A 23's resolution..." "This Halo P 3/A 23 combo is the kind of system that should be celebrated as an invitation to participate in high-end audio as a hobby. And it continues Parasound's tradition of giving people more performance for the money than they have any right to expect." - Shane Buettner
