Benefits of Parasound Halo A 23+ Stereo Power Amplifier:

Impressive Performance Upgrades

The performance of a power amplifier is significantly contingent upon 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 experience the pros of these upgrades as the A23+ ensures there is imperceptible distortion at full power. Other performance upgrades comprise of tweaked input circuits for better crosstalk specs (70 dB at 20 kHz compared to 63 dB) and upgraded internal gold on gold audio connections, consequently leading to a cleaner signal path that's also more trustworthy.

Upgraded Rear Panel Features and Layout with Revised Halo Front Panel Look

The rear panel of the A 23+ has been revised in terms of layout and some breakthrough 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.

The Halo series has always upheld its reputation for its eye-catching aesthetics, and the look is further enhanced. New front panel cosmetics include slim metal end caps replacing wider plastic end caps, also an added gold metallic accent stripe along with the end cap, gold feet now on black units, and an engraved metal "Parasound" badge replacing the red "P."
