True Ribbon™ SR1a.
The world's first Earfield™ headphone monitor.
The SR1a by RAAL-requisite is the world’s first Earfield™ headphone monitor. Experience mixing, mastering, and home listening with unparalleled accuracy and realism in a soundfield devoid of room acoustics and comb-filtering caused by work surface reflections. Earfield™ technology delivers unheard of program accuracy and a speaker-like soundfield experience.
"Well, that was either the most superlative laden, over the top, word salad of a review you've ever read or you're currently adding the SR1a to your online shopping cart. I understand if some readers think I was a bit too liberal in handing out accolades to the SR1a, but I have no problem standing behind every one of them. The RAAL-requisite SR1a is truly a game changer. There's no headphone like it available today, with respect to both design and sound quality."
"The SR1a is the only headphone to ever pull me away from my main two channel speaker based system. This doesn't mean I'm converting from my Wilson / Constellation system to headphones, because nothing could be further from the truth. There are many things headphones just can't do. There's no Johnny Cochran to get one around the laws of physics. However, the amount of time I now spend listening to my main system is substantially reduced because these headphones are so good.""All music lovers, audiophiles, and even gear junkies need these headphones as part of their audio arsenal. It's just that simple. The RAAL-requisite SR1a are unequivocally the best headphones and the most notable audio product I've ever heard. Period. End of story."

"The Raal Requisite delivers a combination of bandwidth, resolution, speed and dynamics like no other headphone currently to market."
Weighing in at only 425 grams (15 ounces). Unlike standard headphones who’s weight and heat create listener discomfort over time. The SR1a Earfield™ design eliminates heat buildup on the ears providing a cool, natural airflow. Your ears will also appreciate the complete absence of sound pressure against the eardrums caused by traditional sealed can designs. SR1a headphones can be worn comfortably for many hours at any listening level.
Remarkable Sound & Remarkable Design.
Unparalleled musicality and detail… A completely adjustable soundstage, able to reproduce a near-field loudspeaker experience (not approximate or fake, but real, two channel imaging).
"A radical departure from traditional headphone designs that presents speed, dynamics and imaging that exceeds flagship planar and electrostatic systems. Arguably the most exciting new development in headphone engineering in a long time."
World class professional monitors I can take on the road! I can finally trust my sound everywhere.

"What else can I say about this stellar combination of the SR1a true ribbon earfield monitors and the HSA-1b that I haven’t already said? It is simply right there with the very best personal audio can get…period! Incredibly transparent, clean and open sounding, this setup really will have you smiling every time you listen to your favourite songs. If that wasn’t enough the ability to have a truly endgame amplifier for even your most power-hungry orthodynamic headphones like the Abyss Phi TC, Hifiman Susvara or Audeze LCD-4, the value proposition of this amplifier really shines through. And if that wasn’t enough, hook up any pair of efficient desktop speakers to the taps on the back of this amplifier and you really have the Swiss Army knife of amplifiers. The HSA-1b has punch, dynamics and a level of transparency that is truly outstanding and will have you staying up late at night just to listen to one more track. If you already own the SR1a headphones and are looking for an end game amplifier, look no further than the HSA-1b amplifier! Especially if you’re like me and have a collection of other great headphones that you’re looking to drive, this amplifier will scratch every upgrade itch you may have in the future!"
