One of the new digital amps that really provides the promise of this technology. It's not a light weight in any sense of the term. I'm sure it can handle any speaker, is stone quiet, small in size but weighs in like a regular analogue amp of high power. I am the original owner and purchased it only 3 months ago to see if I liked this new technology. I do. Original box and packing. I'm selling this amp in order to purchase a multi channel model. Please check the reviews of this amp in comparison to the Parasound A21. Shipping included.
