Parasound A21 amplifier for sale. Excellent condition. This is a very good sounding, powerful amplifier that works very well with speakers that like a lot of power - I've used it primarily with Magnepan 3.7i's and 1.7i's. I have the original documentation, box, and packing. I can deliver within the greater DC area - shipping weight is 74 lbs. so shipping would be costly. $1650. I've reproduced the specifications below. If interested please PM me here.
