In original boxes with accessories. 30/11/23 receipt See my review here: - https://raalrequisite.com/wp-content/uploads/2023/01/Review-of-the-new-RAAL-REQUISITE-CA1a-pdf.pdf https://www.stereophile.com/content/raal-requisites-circumaural-ribbon-headset-ca-1a The CA-1a is a circumaural version of Raal's landmark SR-1a open baffle ribbon headphone. Unparalleled accuracy and realism in a soundfield devoid
A$2,750 is fair-to-good, not a steal, for a CA-1a in today’s used market. New pricing has been around A$4,790, and used listings I found include one at A$2,199, so this ask sits above the low end but still well below new, which makes it reasonable if the condition is genuinely clean and the full package is intact.
It’s worth buying because the CA-1a is one of the more distinctive true-ribbon headphones: fast, open, and highly resolving, with a presentation that can sound startlingly “speaker-like” when driven properly. The value improves if it includes the transformer box, both pad sets, and original packaging, since those pieces matter to the ownership experience and resale. At this price, I’d mainly verify completeness and cosmetic condition rather than worry about intrinsic risk.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
RAAL-requisite emerged from a strategic partnership between two respected names in high-end audio: the Serbian RAAL group, renowned for ribbon tweeters and loudspeakers, and Requisite Audio Engineering, a California-based manufacturer of studio-grade components. The joint venture brought together decades of expertise in advanced driver technology and professional audio design, positioning the brand at the intersection of studio precision and consumer hi-fi.
The brand has carved a distinctive niche through ribbon-driver headphones, most notably the SR1a EarField™ Monitor—marketed as the world's first earfield monitor headphone—alongside the HSA-1b Switch-Drive amplifier. Rather than pursuing a broad product portfolio, RAAL-requisite has maintained laser focus on ribbon transducer technology across headphones and amplification, reflecting a philosophy of specialization over diversification. This narrow but deep product strategy underscores their commitment to mastering a single technology rather than competing across multiple categories.
RAAL-requisite occupies the upper echelon of the hi-fi market, serving discerning listeners, recording professionals, and mastering engineers who prioritize accuracy and sonic transparency above mass-market appeal. The brand's reputation rests on uncompromising engineering, premium pricing, and a devoted following within audiophile circles. Their positioning as a boutique, high-end manufacturer—rather than a mainstream consumer brand—reflects their target audience: those willing to invest substantially in specialized, purpose-built audio equipment.
