One Parasound Halo A21 amplifier. Looks and sounds like new. I am 2nd owner. Purchased here from Audiogon member. I thought it was nosier than should be. Sent to Parasound and had new transformer installed about 3-4 months ago. Now it's pretty much as good as new. No scratches. No issues. Getting away from 2 channel for a while. Balanced and single ended inputs. 250 watts/8 ohms, 400 watts/4 ohms. 74 pounds shipping weight. $1475.00 includes insured shipping and paypal. $1350.00 pick up in Manassas, Va with cash.
