Conclusion: The Audioengine D1 DAC/Amp is relatively inexpensive as DACs go. Even so, at $169, it’s not an impulse buy. You have to decide if the improvement the D1 offers is worth it to you. Audioengine does offer a 30-day audition with full refund if you aren’t satisfied.
Pros: Well built, Improves audio, Strong amp, Affordable (for a DAC), Nice drawstring bag for commuting
Summary: In my opinion, this is as good as the unit of several times more expensive ones.
This is no way inferior to Matrix mini, other than smaller number interfaces to the audio source.
It is also driven by IPAD through USB powered hub.
The design is considerate, compact, and beautiful yet srong.
Summary: Great entry level DAC. Noticeable improvement over the onboard sound of my mac. Pairs great with my audioengine A2s. Powers my HD600 and HE400 headphones very well, seriously can not tell the difference between this and the Asgard 2 (which very much disappointed me for the price).
Pros: Great value, sounds great, drives all my headphones well
Summary: I was looking for a work solution to drive my relatively low impedance headphones I use at work (Shure SRH840 and Grado SR225e), while also being able to feed my powered desktop speakers (BOSE companion II).
Pros: small size, build quality, features, spaciousness, liveliness
Cons: Slightly underpowered for hard to drive headphones, no marking on volume knob
Summary: Used with studio monitors and Beyerdynamic DT-990 250 ohm headphones.
Nothing really bad to say about this DAC/Amp. The build quality is high, size is small, it drives all headphones I tested it with well.
Pros: Value, sound, build quality, size, volume control
Excerpt: For many older audiophiles, their “conversion moment” when they discovered the world of high-quality sound began when they heard their first piece of affordable high-performance audio gear, such as the NAD 3020 integrated amplifier. But what about today’s audiophiles with computer-based systems?
