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.
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.y.
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.
