Parasound HALO A21 2 Channel
High Current Power Amp

We have a client who is doing massive
upgrade to his system and I am selling his 2 amps for him (which are listed under
separate listings). 

 This amplifier has a small nick on the top
edge toward the right side which you can see in one of the pictures which is barely noticeable but the fact that it is there is the only reason why this unit is rated 7/10.
