Parasound launches a flagship stereo power amplifier-- the Halo JC5, designed by respected audio expert John Curl and promising to boil down "the essence of the two top-of-the-line Halo JC1 monoblock power amps into a single chassis."
The design features a high power and ultra-high bias Class A/B topography able to deliver 400W per channel. High bias A/AB provides 12W per channel pure class A power and class AB to the 400W per channel 8 ohms rating. It delivers 600W per channel into 4 ohms, and can be bridged to mono for 1200W into 8 ohms. The output stage features 24 beta-matched, 15 ampere, 60MHz bipolar transistors to deliver peak current of 90 amperes. Meanwhile the power supply employs a 1.7kVA shielded toroid power transformer with a H18 grade steel core. It has independent secondary windings for the dual-mono power supply.
