This Halo Shines More Beautifully Than Ever

Parasound already brings listeners heavenly sound, but its halo now shines more beautifully than ever with its brand new version of the Halo A 23 two-channel power amplifier. Meet the Halo A 23+ and enjoy performance upgrades for cleaner, ultra-low distortion sound, revised front panel cosmetics, and a revised rear panel layout offering enhanced features, too.

“Together, the Parasound P 6 and A 23+ are dynamite,” raves Roy Ervin Solstad, Stereo+ (Norway), January 2019. “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.”

Impressive Performance Upgrades

The performance upgrades are impressive, beginning with a big 25% to 30% increase in output power compared to the previous model. The A 23+ delivers 160 watts-per-channel at 8 ohms compared to 125 watts-per-channel for the A 23, 240 watts-per-channel compared to 225 watts-per-channel at 4 ohms, and 500 watts in bridged mono mode compared to 400 watts with the A 23.

The performance of a power amplifier is highly dependent on the quality of its power supply, and Parasound went the extra mile with the A 23+, which boasts a 10% to 15% larger main power transformer compared to the previous model A 23. Transformer size has been increased from 1.0 to 1.1kVA, and the filter capacitance increases 20-30% from 40,000 uF for the A 23 to 54,400 uF for the new A 23+. You’ll hear the advantages of these upgrades as the A23+ presents lower distortion at full power.

Other performance upgrades include tweaked input circuits for improved crosstalk specs (70 dB at 20 kHz compared to 63 dB) and upgraded internal gold on gold audio connections, resulting in a cleaner signal path that’s also more reliable.

Rear Panel Layout and Features Upgrades

The rear panel of the A 23+ has been revised in terms of layout and new features. It boasts upgraded speaker terminals, using identical terminals to the HINT 6 integrated amp, a new jack/terminal layout with more space and more clear text/labels, and a master “Vacation” AC switch. The 2.5mm trigger jacks of the A 23 have been replaced with 3.5mm jacks, and the audio trigger circuit has been updated for better low signal reliability.

Revised Halo Front Panel Cosmetics

The Halo series has always been known for its elegant aesthetics, and the look is even better than before. New front panel cosmetics include slim metal end caps replacing wider plastic end caps, an added gold metallic accent stripe along the end cap, gold feet now on black units, and an engraved metal “Parasound” badge replacing the red “P.”

Advanced John Curl-Designed Circuitry

The circuitry of the A 23 was engineered by legendary audio designer John Curl. Its direct-coupled topology uses no capacitors or inductors in the signal path for pure, uncolored sound. Balanced inputs with discrete circuits and XLR connectors yield dead quiet operation. The complementary JFET input stage and MOSFET drive stage incorporates 12 beta-matched 15 amp, 60 MHz bipolar output transistors for pristine sound. The high-bias “Class A”/”Class AB” operation blends best sound with highest efficiency performance.

The A 23’s custom-made, high-current power supply is specially designed for exceptionally quiet operation along with ample power for climactic music passages. The 1.1KVA encapsulated toroidal power transformer uses independent secondary windings for each channel along with a 54,400 µF power supply filter capacitance. DC servo and relay protection circuits keep operation safe and reliable. And Parasound backs the A 23+’s reliability with an impressive warranty.

No Need for a Remote

The front panel of the A 23+ looks great even when the unit is turned off. When you switch the Halo on, LEDs display AC-present, channel, and high temperature status. Adjustable signal sensing can be set to automatically power up the A23 when it receives a signal from your preamp or other compatible component (or when it receives a 12-volt trigger command), eliminating the need for yet another wireless remote!

‘Instant Warm-up’ Feature

Like all the other amps in the Halo product series, the A 23+ has Parasound’s exclusive bias circuit, which permits the amplifier to sound perfect from the instant it’s turned on, rather than having to wait for bias to gradually build up as the amp warms up over time. Even Halo’s implementation of its automatic turn-on feature is exceptional. Special relays bypass the AC “soft start” circuitry after it’s done its job for the purest AC and the purest sound.

Parasound

As the nationally recognized leader in the field of high-end audio, home theater and home electronics, Overture is proud to offer Parasound’s line of high-performance music components including the new Halo JC 1+ that is the ultimate achievement of Parasound legendary designer John Curl. In the complicated landscape of audio, many companies put stratospheric price tags on great performance. Parasound’s mission couldn’t be more different. Simply put, they offer the most performance for the money by finding the sweetest spot between price and diminishing returns. Everything they do at Parasound is customer-centric because that’s how they define value. When they develop a new product they take the carpenter’s adage “measure twice, cut once” to the extreme. Each new model is tested, improved and re-tested under worst-case conditions. It comes to market only when it is a finished product that’s ready to stand the test of time. In fact, they don’t really know how long their amplifiers last because people write to thank them because the Parasound amp they purchased in the mid-’80s still works perfectly 30 years later. When you choose Parasound you’re getting uncompromised quality for every model. They all use the best parts and each must pass their strictest quality assurance. They wouldn’t have it any other way.
