Categories: Audio, Power Amplifiers, Receivers & Amplifiers SKU: HALOA31B

The Parasound HALO A31 multichannel amplifier is a power amplifier that draws directly from the hefty lineage of the 5 channel A51. Like it’s bigger brother – the it’s also a THX Ultra 2 certified product, but the interesting backdrop to the A 31 is that it was designed in response to increasing demand for a three channel power amp that holds nothing back in power or performance. So the A 31 is identical in performance and sound to the award winning Halo A 51.
