This is the matching power amp to the P-5 preamp that we also have for sale. The A21 is a 250W/8 ohm powerhouse that balloons to 750W when used as monoblocks. That is an astounding amount of power for the money. Add premium built quality, gain controls, selectable XLR or RCA inputs and ground lift and the A21 becomes a technical gizmo. Of course, the icing on the cake is the sound quality of the amp. If this amp was auditioned with a cloak over the amp, you would have thought you were listening to a McIntosh or a Levinson amp. That was how good it is. It drove some power hungry speakers we have in the store with great finesse and its only when you placed this amp in a far “richer” crowd (we are talking about north of $10,000 components) can you then start to pick on some of the differences between it and the its more expensive counterparts.
Cosmetically, the A21 is in great shape. Just minor signs of use. We have the original box and manual. This is a current model in Parasound’s lineup.
