“The ALO Audio Rx Mk2 portable headphone amplifier has been a wonderful, reference tool that has served Playback (and its readers) well in countless evaluations of high-performance earphones and custom-fit in-ear monitors. The Rx Mk2 is one of those rare components that can make all types of music and most if not all types of earphones/headphones sound their best. Though not inexpensive, the RX Mk2 does it all, offering clarity, detail, tonal purity and richness, and faithfully conveying the life and natural warmth of the music.”
“What can the RxMkII drive? Anything. That’s not a typo or ill-considered hype. Using Ken Ball’s 3.5-to-6.3mm wired adaptor, the toughest loads I could throw at his small amp were Fang Bian’s HiFiMan HE-6 and HE-5LE orthodynamics. Nobody should/would walk the streets with them or any other expensive full-size headphone on a silly 3-meter leash. At home meanwhile, if such an amp could replace a regular wall-powered component, why not?”
“Original vs. MkII: Bass power improvements in mass, impact and reach were the obvious difference on all my earspeakers but particularly impressive with headfi’s godzilla of bass, the recabled Audez’e.”
“Out of the box, it was immediately apparent that this thing was quality. Having been more accustomed to reviewing in-home amplifiers, I had more of a desire for hearing a portable with a beefier sound. The RX prescribed just the cure for that. I was able to drive quite a variety of headphones with authority.”
“The RX is a phenomenal sounding headphone amplifier, with it’s main characteristics being it’s tight, controlled and punchy sound. Instrument separation is the best we’ve heard in a portable, and there is a great sense of balance and accuracy that is commonly missing in the portable market. We were able to drive a variety of both IEM’s and full sized headphones, making the RX MK2 versatile enough to use with most headphones out there. Our reviewers, preferred the RX MK2 over the Corda Move, Fiio F7 and what USED to be our reference amp, the RSA Hornet.”
“Having mostly the same sound signature as the original Rx, the question of “is it worth upgrading?” would be asked by most of the original Rx owners. Comparing the two amplifiers, the new amp has a slightly larger soundstage, a bit more forward presentation, and a little more bass presence. Not only is there more bass quantity, but the punch is also stronger, especially when driving fullsize headphones like the LCD-2. The Mk2 is one of the punchiest portable amplifier around. The new amplifier is also slightly smoother and more refined.”
“The Rx has always been a superb portable amp, and the Mk2 will undoubtedly be another favorite. If you are looking for a portable amplifier, the Rx would be one of the amplifiers that I recommend.”
IMPORTANT - Please note: For critical listening if using a cell phone as a music source we highly recommend setting your phone to "airport" mode or turning off the cell send and receive function. The Rx Mk2 amplifier warranty does not cover cell phone noise as a warranty issue as all portable amps will be susceptible to this interference when a cell phone is placed on top of the amp. We could have used a slightly more insulated chip set, at the cost of weaker sonic capabilities. ALO's goal is to make the absolute most dynamic and best sounding portable amp in the market and the components used the the Rx Mk2 does not compromise for overall sonic performance. We use a iPhone 4G with a Wi-Fi network and experience negligible instances of cell noise with all networks ON.
