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 a cleaner, ultra-low distortion sound, revised front panel cosmetics, and a revised rear panel layout offering enhanced features, too.

• Impressive performance upgrades: The performance upgrades are impressive, beginning with a big 25% to 30% increase in output power compared to the previous model.
• Parasound went the extra mile with this one: Boasting a 10% to 15% larger main power transformer compared to the previous model A 23. You'll hear the advantages of these upgrades as the A23+ presents lower distortion at full power.
• 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.
• No need for a remote: The front panel of the A 23+ looks great even when the unit is turned off. Adjustable signal sensing can be set to automatically power up the A23 when it receives a signal from your preamp or other compatible component eliminating the need for yet another wireless remote!
