Parasound TOP Reference Series Halo Series, Differentially Balanced 125-Watt Stereo Amplifier into 8 ohms. Fantastic sound and value. It is no secrete that I and many in the know find the Parasound Halo Series Products (their top Reference Series) to be the best value to be found in electronics. Taken in trade on the A-21 higher power amplifier also available here. One owner, cared for but wear and some scratches (see pictures). If you do not have a more local dealer we have a demo like new for a $155 more in like new condition and is as new. Please call if interested in our demo and or you have questions. The Halo A 23 power amplifier is FTC rated at 125 Watts RMS per channel from 20 Hz -20 kHz into an 8-ohm load with both channels driven; 200 Watts into 4 ohms; and it can be bridged to 400 Watts mono. All this power is provided by 12 beta-matched 15-amp, 60 MHz bipolar transistors that can handle 45 amps peak current per channel. The heavy-duty power supply uses a massive 785 VA toroidal transformer with independent secondary windings for each channel, and 20,000 µF capacitance per channel for energy to spare. The transformer windings are fully encapsulated in epoxy and a heavy-duty steel case to eliminate the possibility of transformer hum, and large extruded aluminum heat sinks avoid the need for a noisy cooling fan. With fully differential balanced inputs using professional XLR connectors, the A 23 has exceptionally low noise and distortion levels, and there are no capacitors or inductors in signal path. The pure Class A discrete component matched J-FET input stage, and MOSFET driver stage, give the A 23 with a warm tube-like sound, and the double-sided FR4 circuit board provides a superior ground plane to reduce noise. There are rear-panel XLR and RCA inputs, RCA loop outputs, robust 24 kt gold-plated five-way binding posts, and a DC trigger input and loop output connection. Other features include auto turn-on by audio signal with adjustable sensitivity, and a ground-lift switch to eliminate the hum that is often a problem in rack-mount installations. The A 23 fits in a 2u rack space, has relay protection circuits, a thermal overload indicator, is switchable 115/230v AC, and has an illuminated power button and logo badge.
