–Reviews

“So what is the verdict on the ALO Audio Studio Six and Phono Stage? It is an audio triumph. You may find another amp you like as well but it is unlikely you will find one that is definitively better. This is a mountain top amplifier. It pairs well with Dynamic, Planar, Open, Closed and Semi-Open headphones. The Studio Six itself is the single best Headphone Amplifier I have ever heard paired with the Sennheiser HD800’s. Using the Phono Stage with vinyl is sublime. Paired with a high quality DAC like the Wyred 4 Sound DAC2 DSDse and digital comes through as natural and engaging.”

“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.”
