Afterdark Project ClayX GIESEMANN OCXO Clock - Emperor Double Crown Master Digital Clock For sale is my Afterdark Emperor Double Crown clock. This was used as a significant upgrade to an Etherregen. As I no longer stream, the clock is no longer required and is for sale. It was purchased from the manufacturer in 2022 (receipt available), is in excellent condition and includes the Mogami clock cable pictured. It does not include a power supply (12v). It also does not come with original packaging, but will be carefully packed for shipping. Please see the manufacturer website for further speci
The clock angle is what makes this one notable, but at A$1,750 it is still very ambitious against the local used market. With your database anchor at a A$493 median, A$358 25th percentile and A$567 75th percentile, this listing sits far above even the upper quartile, so I’d treat it as a specialist-pricing ask rather than a normal fair-value buy.
That said, if you specifically want this calibre of master digital clock, the upside is the precision-focused reputation and the appeal of a premium, well-kept example in excellent condition. For a buyer who values the design, OCXO stability and the rarity of the piece more than resale math, it can still make sense — but only if the package is complete and you’re happy paying for scarcity rather than market benchmark.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Crown Audio traces its origins to 1947 in Elkhart, Indiana, where minister and radio enthusiast Clarence C. Moore, alongside his wife Ruby, founded the International Radio and Electronics Corporation (IREC) in a converted chicken coop. Initially focused on rugged open-reel tape recorders for missionaries in remote regions, the company pioneered innovations like the world's first tape recorder with a built-in power amplifier in 1949. Ruby's suggestion in the 1960s led to the adoption of the Crown name, inspired by the crown emblems on their 'Royal' and 'Imperial' models, with the corporation officially renaming to Crown International, Inc. in 1975.
The brand shifted from tape recorders and compact loudspeakers in the 1950s to standalone tube power amplifiers by 1959, cementing its expertise in professional amplification. Crown became renowned for groundbreaking products like the DC300 in 1968—the first high-power solid-state amplifier—and the M600/M2000 in 1972, featuring patented technologies such as the ground-bridge circuit. Today, under Harman International since its 2000 acquisition, Crown specializes in high-output amplifiers for touring rigs, cinema venues, installed systems, portable PA, and commercial audio, prioritizing reliability and innovation over consumer categories like speakers, turntables, DACs, headphones, or cables.
Crown holds a commanding position as a pro-audio powerhouse, trusted by industry leaders for its durable, high-performance amplifiers that define live sound and installation standards. Far from high-end audiophile or vintage collector fare, it dominates the professional market with over 75 years of technical milestones, though recent production shifts to Mexico reflect ongoing evolution. For the discerning hi-fi buyer eyeing pro-grade power, Crown delivers uncompromised authority.
