Parasound A 21 2 Channel Power Amplifier

Please note: This unit is 220-240v and includes shipping :)

The Parasound A 21 is one of the best amplifiers we have heard sub 10k this means a lot considering the A21 retails for 5K (AUD$)! The A 21 has an abundance of high current power and will run a pure class A at lower volume levels.

We have a traded A21 in black. the unit is in excellent condition. original box included
