Audioengine built the D1 as a complete digital to analog audio solution. Instead of requiring an external amplifier, they built an amp into the D1. Just plug your headphones into the front jack and you're ready to enjoy top quality headphone sound.
Take the plunge and give it a listen, you won't be disappointed.
