Tone Audio

"The Studio Six from ALO Audio redefines what headphones are capable of delivering, from the least expensive to the most exotic cans in your collection...

Its ability to drive every type of headphone also makes the Studio Six an incredibly versatile tool as a reference component, so expect to hear more about this landmark product in the issues to come as it will be my reference amplifier by which to evaluate all other personal audio gear."

-Jeff Dorgay @ Tone Audio Issue #57

 "Exceptional transparency combined with oodles of tone furnishes the listener with both high and low volume satisfaction. It won’t bend or buckle under the strain of higher impedance cans. That’s its bare essence.

You’re also buying into confidence and eliminating doubt. Doubt that there’s a better amplifier out there for your favourite ‘phones, doubt that such a beast could make them sound even sweeter, more three-dimensional, more tonally saturated. Make no mistake, ALO pack these sonic attributes into the Studio Six for an endgame product with few rivals." 

- John Darko, Digital Audio Review

" The way we interact and listen to headphones is changing rapidly, and the Studio Six is at the head of the pack in high-end desktop personal audio. I can't get enough of the damn thing. Ken Ball and his team have reason to be proud. The Studio Six is a blast to listen to, and its aesthetics are modern and clean....Most highly recommended."

"The Studio Six isn't just an amp. It is a statement, that punctuated by precise engineering, utilitarian design, and excellent performance, has other amps blubbering...ALO proved yet again that they are not merely product designers. They are tinkers. They are engineers. They are artisans."

- Nathan @


"The Six truly has what it takes to stand the test of time...ALO has really nailed it with the Six. The sound wasn’t what I expected, but they’ve made a convert out of me. Sure I think their smaller amps are great, but the Six really deserves that flagship title as it’s leagues ahead of the other ALO amps."  

- Mike @

"...What I am hearing is excellent -- the music -- but delivered with a high level of detail and in a manner I would describe as absolute, that is, with an unapologetically accurate attitude that shows you exactly how the music is from the lowest bass note up to the highest treble. Not only the capabilities and flaws of the music but of your headphones as well.... The Studio Six was delivering the music so precisely that I was hearing the music exactly as it was and exactly as everything else in the rest of my system was capable of delivering it." 

-Amos "Currawong" Barnett,

"I'd have to say that the ALO the best that I've heard in a headphone amp. Reference-quality, without a doubt, and massive synergy with the Audeze LCD-3's." 

-David W. Robinson
