Continually improving our favorite products is our passion as well as our pastime. This newest generation of the Rx Mk3 is the latest result of that effort to make our products even better. An all new, larger battery in the B+ means more time to enjoy your favorite tracks. And higher surface mount parts tolerances throughout means that those tracks will sound even better. Lasting 19+ hours on a single charge gives you the peace of mind to simply grab your Rx Mk3 B+ and go, knowing you’ll be able to enjoy the music for the full trip. New improved double laser engraved permanent marking on our enclosures mean the markings will remain clean and clear through all your trips! The new improved Mk3-B + has never sounded better, with bigger dynamics, improved imaging, detail and sonic impact.
“The ALO Rx Mk3-B is a solid complement to any desktop space. Top tier portable audiophile performance lies just beneath its metallic exterior. Considering the battery power and relative size, the Rx is very much a product of convenience.”
“I still can’t fathom how the slim Rx Mk3-B amplifier is able to drive the Hifiman HE-6 so brilliantly. I’m not saying it defies the law of physics, but I know how difficult it is to drive the HE-6 and I’ve seen the majority of desktop amplifiers, even BIG ones that fail to deliver the job. The Mk3-B not only drives it with sufficient authority, but it strikes such a beautiful synergy with the Hifiman as well.”

“If you could only choose one headphone amp to meet all your listening needs, this one belongs at or near the top your short list. It’s one of the two best portable headphone amplifiers now being produced.”

“Though professional cynicism is supposed to mistrust a maker's self-salutary 'best we ever made' statements, the Mk3 straight—single-ended in/out, zero bass boost—really did trump the Mk2 and original Continental...Kudos to Ken and his team for pursuing their dream to the very end.”
