The 'Halo' range by Parasound is their crowning achievement. The Halo A21+ is a refinement of the legendary John Curl designed A21 power amplifier. The A21+ continues the authoritive, real world speaker driving force of the original design and builds upon this with increased power output, bigger power supply with improved distortion and signal to noise ratio. This translates to more control, better dynamics and more detail.
We have found the Parasound A21+ to have great control over every speaker we have paired it with (including low Impedance, low Sensitivity models) and feel confident that you will too. If you're after a big, powerful sound with plenty of grip and drive this amp is sure to impress.
