Parasound A-21 Class A/AB Amp [Expired]


no longer for sale

I'm the original owner of this fantastic Parasound Halo A-21 amp, its only 3 months old so as you can imagine it's in excellent condition... my loss is your gain!! I've decided to now move to an all valve system so my A-21 is up for sale. These amps don't come onto the used market often simply due to their top class performance. Read the reviews. I don't have original boxing but will carefully double box the unit and can assist with international shipping. Item is in factory 220-240v trim. Preferred payment by direct wire.
