Just Ask Audioengine
If you look at the Audioengine website, you'll see something rarely seen; links to positive reviews of their products from non-audio press: PC Magazine, Macworld, Wired, PC World, and even Gizmodo, haters of all things with the word "Hi". Of course Audioengine also gets positive reviews from the audio press. How do they do it?

They do it by consistently building very good sounding and good looking stuff that doesn't cost a fortune. Crazy, right? I reviewed the Audioengine A5+ (see review), their B1 Bluetooth Receiver (see review), and the D2 Wireless 24-Bit DAC & USB-S/PDIF Converter (see review), and we bought our daughter's each a pair of the little A2 speakers for Christmas many years ago. The other part of the Audioengine secret sauce is they offer products that fill a need and they're not afraid to embrace things that tons of people want, like Bluetooth and Toslink (think Apple TV). Crazy, no?

The Audioengine HD6 are the company's new flagship active speakers. The left speaker weighs more than the right because lefty houses all of the electronics, leaving righty passive. There's a 50WPC Class A/B amp (150W peak power total), a 24-bit DAC for the aptX Bluetooth and Toslink input (supports up to 24/192 via Tosliank), and all of the ins and outs listed above. Righty is connected to lefty with an ordinary run of speaker cable (Audioengine includes a 6' run). The drivers consist of a 5.5" Kevlar woofer and a 1" silk dome tweeter, the woofers employ a diecast aluminum frame to better deliver the bottom end with rigid force. The HD6's come in your choice of Satin Black or furniture-grade Walnut or Cherry wood veneers.

I sat the HD6s on my desktop connected to the Mytek Stereo192-DSD DAC, which is turn is connected to my iMac via Firewire. Setup took all of a few minutes. The left speaker has a front-mounted volume control knob but Audioengine also includes a very nice little hefty-feeling aluminum remote for controlling volume, mute, and sleep mode (they must get people's hatred of cheap, plastic remotes with tons of useless buttons). As you can see, there's also a decorative aluminum horizontal strip on each speakers face with the engraved Audioengine logo. A subtle white power LED sits behind a metal screen in the left speaker finishing off the visuals. There are also magnetic grills, which I preferred off, but some may find this look too naked (they must also get people's hatred of unused holes in an otherwise attractive speaker's face when the grills are not in use).

The review pair came in the Walnut finish, which is my favorite. My only complaint is due to the fact that I received a "test run" pair so the left speaker's front face had imperfections where it meets the top. I was assured by Audioengine that every pair going to customers are inspected and this pair never would have passed muster. Good to know. I sat the HD6's on my IsoAcoustic stands, a must-have accessory for any desktop speaker, imo.

The Audioengine Tradition
Easy to listen, easy to like. That's what I get from Audioengine but the HD6's add an adverb, namely "really", twice. The HD6's sound bigger and more coherent than my memories of the A5+ and they certainly have more grunt, drive, and punch as compared to my tinier ADAM A3X. The new Audioengine's also have a silky smooth sonic character, removing any hints of harshness attributable to the tweeter. As a matter of fact, the HD6's sing as one voice, with nary a hint of their two-way-ness.

Also unlike my A3Xs, do not think of the Audioengine HD6's as desktop speakers. These speakers really enjoy volume and I'd imagine they'd live very happily in a small room. I found myself toeing them out more and more and getting them as close to the edges of my desktop as possible so I could better fill my surrounding space with music. Big, loud music. Kamasi Washington's The Epic was a perfect partner with its horns, strings, prominently mixed drums, and voices. The Epic is, well, epic, and it really begs for big and loud and the HD6's were happy to accommodate. Nice.

That's not to say they don't do subtle. One of my favorite albums of all time, Mal Waldron'sThe Quest, was easy to fall into through the HD6s. Eric Dolphy, Booker Ervin, Ron Carter (on cello), Joe Benjamin, and Charlie Persip weave sheer beauty, especially on "Warm Canto", and the Audioengine's provide all the warmth necessary for a moving experience. If there's one aspect of the HD6's performance that I'd call attention to, it's that I did not find them as enjoyable at lower volumes as compared to my ADAM A3Xs. I'm talking about lower-your-voice levels so this may not be an issue for most listeners. The best desktop speakers I've heard in this regard, the ability to still sound amazing at whisper quiet levels, were the Fujitsu Ten Eclipse TD-M1 Wireless Speaker System ($1,300.00/pair see review).

Of course the HD6's also love romp and roll and Jimi Hendrix playing "Red House" live at Clark University (1968) sounded smashing as did D'Angelo's entire Black Messiah. Again, the temptation for loud, and louder still prevailed. The HD6's are also kind to less kind recordings because of their relatively warm sound. While I'm really diggin' the new U.S. Girls Half Free (a lot), it is not what you'd call an audiophile recording. Listening through the HD6's, that stuff falls by the wayside leaving you and the U.S. Girls to get on with more important matters.

Since my listening stayed on my desktop in the barn, I did not do much listening via Bluetooth but I did do enough to be able to say with confidence that only the most persnickety will find fault and not fun. I streamed music from my iPhone via the very cool Bandcamp app which provides access to all of the music you've purchased from the site as well as other selections. The way I see it, with the HD6's set up in-room, Bluetooth becomes your ticket to inviting friends and family to play through your hi-fi with a few taps on their phone. Can you spell party?

Last but not least, I leashed my MacBook Pro directly to the HD6's with a length of optical cable, relying on the speaker's DAC. fka Twigs' latest, Duke Ellington Afro Bossa, Rokia Traori's lovely Beautiful Africa all sounded lovely. Granted on purely sonic terms Toslink to the HD6's did not sound as natural or musically engaging as going through the Mytek DAC, a combo I could live with, but for users with a Toslink-equipped computer, Toslink + HD6s offer a very simple solution. Just add your audio player of choice.

Really easy to listen to, really easy to like
I've been to people's homes where they have a computer and some desktop speakers setup in their living room as their only hi-fi. Typically the speakers are too small for the job of listening outside of the desk so when asked to fill a room they fail. Can you say crappy party? I found the Audioengine HD6's to beg to be played loud(er) as if they were born to fill a room.

While the Audioengine HD6's worked perfectly wonderfully on my desktop, if you're also going to ask your desktop speakers to do double-time in-room, the HD6's are bouncing out of their seat, waving their hand, and shouting "Pick me!, Pick me!".

which particular model of isoacoustic stands did you use for the audio engine speakers? Great review, I was just about to purchase a pair of Adam A5x's , i think this article altered my course.

...SO-L8R155 stands. IsoAcoustics has a calculator on their site (www.isoacoustics.com/calculator/#/) that tells you which stand to use for your speakers.

Great review, thank you! I see that you also reviewed the Xeo 4. How would you compare the two in terms of sound quality? Of course the Dynaudios are quite a bit more expensive but in functionality and size they're quite comparable. Looking for a powered solution that will provide high-quality sound (primarily classical) in a small room, source being an Airport Express. Many thanks.

The Dynaudio's are simply better speakers. I preferred the X14A to the XEO's unless you want/need wireless.

Michael, does the main speaker have a sub-out, I have a pair of Cakewalk monitors that are getting long in the tooth with my MacBookPro but still want to incorporate the 8 inch sub.

...for connecting a sub.

Any chance the new Dynaudio Xeo2 are on their way for review? I would love to know how they compare to X14A and BM5 mk3...

So as I read this review I noted your call out of the album in the subject line. I was intrigued, and Amazon had this for $7.00 on a lightning deal so I pulled the trigger on it and it arrived today. I have not opened it yet, but, tell me what you like about it so much, what should I be listening for in this disc so I can understand the experience?

Listen to the entire album all the way through. Then, do it again at your leisure. And again, etc. Sooner or later, you'll be telling me things I didn't know ;-)

Thanks for the review. Can you please comment how much better, sound quality wise, the HD6 is compared to their 5+.The HD6 is $350 more than the 5+. Let's say built-in DAC adds $150, Bluetooth adds $50, the HD6 is still $150 more expensive than (5+ w/ DAC w/ Bluetooth). Does the HD6 sound $150 better?

And how does the HD6's sound quality compare to the KEF X300?

Thank you.

Better sound than the Focal Alpha 50?
