Audioengine 5+ (A5+) Speakers and D1 DAC Review

Posted September 7, 2012 by Sam Chen in Reviews

Audio Bliss and Just a Little Bit More

As someone who’s constantly on YouTube, there’s one thing I frequently notice. Good audio is just as important if not more important than great video. Think about the last time you watched a video on YouTube where the creator obviously shot the video off a pretty high end DSLR, but decided to use the integrated microphone for the audio. How was that? Probably pretty terrible, right?

Yup, and because audio is so important to our computing experience, that’s why today we’ll be reviewing the Audioengine 5+ speakers and the Audioengine D1 DAC. For those unfamliar with Audioengine, Audioengine is a relatively new player in the computer audio industry, but the guys behind the name are definitely not new to the audio industry itself. After spending many decades developing high end studio monitors, the founders of Audioengine decided to create a speaker with studio monitor level quality for the home audience at a reasonable price.

Meet the Audioengine 5+ (A5+)

Let’s talk a little about the Audioengine 5+. The Audioengine 5+ is Audioengine’s flagship powered speaker which Audioengine claims will “deliver audiophile-quality sound and features at a price that continues to set the standard for affordable high-quality audio.”

The Audioengine A5+ includes Audioengine’s custom designed 5″ Kevlar woofers, 20mm silk dome tweeters and custom 2.5″ MDF cabinets. It also features a fully custom class AB 50w RMS per channel amplifier so those looking for a high end pair of speakers for their computers won’t need to go out and purchase an additional amplifier just to use those speakers.

Meet the Audioengine D1

As music in a computer is digital, you’ll need something to convert the digital signal into an analog signal so speakers such as the Audioengine 5+ can play the audio associated with the signal. This is where a DAC, or Digital Audio Converter, comes into play. Now most if not all computers have DACs, which come in the form of integrated audio, but these DACs are typically poor quality components that are extremely susceptible to crosstalk and various other electrical signals running through a computer motherboard’s PCB.

With the Audioengine D1, the entire device is outside of the computer and connected via USB only, which means less interference from other electrical devices. In addition, Audioengine has dropped in a lot of high end audio processing components such as the well known AKM4395 digital to analog converter and an integrated headphone amp based off the TI NE5532, which is an excellent amp capable of driving higher end, higher resistance headphones as well.

    Nice review! I actually had heard a lot of good feedback on these speakers recently

  • homestaymom

    They ARE heavy on bass to the point the mids are a little behind the bass making some voices seem to also sit behind the bass. That drove me nuts so mine are going back.

  • Callum

    I have owned a pair of A5+ speakers and the S8 subwoofer for several months now and I am still amazed by them everytime I watch a movie, game or listen to music. Simply the best.

  • Jeff Grossman

    Awesome review — I love these A5+s. Didn’t realize they fit banana plugs, and when I bought some the plugs don’t seem to go in all the way. Is that how they are supposed to be? Or can you recommend which kind of banana plugs you used? Thanks!

    • Sam Chen

      Thanks! Yup. I think that’s how it’s supposed to be. The plug sticks out a little bit on the end. As long as they’re helping make a good connection between the wire and the speaker I think that’s all that really matters.
