Stanford Research Systems (SRS) Perfection 10 (Perf10) Master Digital Clock I've had this Rubidium Atomic Clock and Plixir Elite Balanced DC (BDC) power supply for four years, and the pair has done stellar service as a reference clock to my dCS Vivaldi Clock. I chose it over the Cybershafts, Mutecs etc. It might not be pretty, but it does a fantastic job! While I only used it with the dCS Vivaldi Clock, it should also work with other brands that have a 10MHz 75 ohm input, such as Esoteric and CH Precision. With its eight outputs you should be fine to clock all sorts of things. This is the
A$4,500 is a bargain against your A$41,623 median and sits massively below the A$35,126 25th percentile, so this is priced like a fast-moving clearance rather than a normal used listing. In other words, if the item is genuinely the digital clock described and it powers up cleanly, the asking price leaves a lot of room for a confident buy.
That’s especially attractive because a good master clock is the sort of piece that quietly lifts a whole digital front end: lower jitter, firmer timing, and a more coherent, settled presentation are exactly why people chase these. The upside is strongest if it’s complete, well cared for, and comes from a careful owner; at this price, the main check is simply that the unit is authentic, functioning, and includes any needed power or interface bits.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
CH Precision emerged from Switzerland's precision engineering heritage, founded in 2009 by Florian Cossy and Thierry Heeb in the town of Préverenges near Lausanne. The duo, whose surname initials inspired the brand name (with a nod to Switzerland's "CH" abbreviation), honed their expertise in the 1990s at Goldmund before launching OEM Anagram Technologies, renowned for its high-performance DACs. Encouraged by distributors, they established CH Precision to pursue uncompromising audio design.
The brand focuses on modular, upgradable electronics at the pinnacle of hi-fi, including preamplifiers, power amplifiers, DACs, phono stages like the recent P10, and integrated systems. Their products emphasize longevity, with components selected for enduring performance and a flexible architecture that supports ongoing enhancements—rare in an industry prone to obsolescence.
Positioned firmly in the ultra-high-end market, CH Precision commands respect among discerning audiophiles for its Swiss-watch-level craftsmanship and musical transparency. Operating from dedicated facilities for R&D, manufacturing, and listening, it delivers components that prioritize engineering integrity, earning a boutique reputation for systems that evolve with user needs while sustaining a core lineup for over a decade.
