OAD Ultrafidelity UF-1 Power Amplifier For those in the know, this amplifier should need no introduction. Designed and built in Australia by Jon DeSensi of Music Labs fame, the UF1 is a hugely capable amplifier, designed to be able to drive complex loads with ease. Huge capacitor power ensures heaps of reserve power for highly dynamic music. From the OAD website: The UF1 is extremely fast with ultra-bandwidth and has a high current capability. The amplifier copes gracefully with impedence dips to 4 Ohms and lower. As the load impedence of an amplifier is decreased to below 8 Ohms large s
Timing matters here because this is an older power amp in a mature product line, so the real question is whether you want this generation’s sound rather than waiting for a newer replacement. At A$3,000, it looks like a strong deal versus the recent AUD comps: it sits well below the A$4,966 25th percentile and far under the A$4,988 median, so this is priced like a bargain rather than a merely fair buy.
What makes it worthwhile is the usual appeal of OAD Ultrafidelity gear: serious build, audiophile-first execution, and the kind of no-nonsense power amp that can anchor a system without fuss. If it’s clean and working properly, the upside is getting into a respected piece of kit at a price that leaves room for servicing or re-cabling if needed. For a well-regarded amp at this level, that’s exactly the sort of listing seasoned buyers should move on quickly.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
OAD Ultrafidelity emerged in 2015 from Melbourne, Australia, founded by veteran designer Jon De Sensi. Operating out of his home workshop, De Sensi drew on decades of high-end audio expertise, including his earlier Music Labs venture in 1990, where he pioneered advanced DACs, preamplifiers, and power amplifiers while engineering for Australia's Department of Defence. His collaborative spirit shone through contributions like the digital stages for Redgum's RGCD2 CD player, cementing his reputation before launching this boutique brand.
The lineup centers on meticulously crafted amplification and source components, including fully discrete Class A preamplifiers like the Padma, robust power amplifiers such as the Vajra, MM/MC phono stages like the UP1, and a versatile DAC/streamer. Dipole speakers round out the offerings, all hand-built with unique topologies emphasizing purity and performance. These Australian-made pieces prioritize solid-state innovation over mass production.
Positioned as a niche high-end contender, OAD Ultrafidelity earns acclaim for "staggeringly" flawless sound and cutting-edge design, appealing to discerning buyers seeking Melbourne-crafted excellence. Reviews praise its smooth, authoritative delivery, though as a relatively new player, it thrives in specialist salons rather than mainstream dominance, backed by three-year warranties and premium pricing around $10,000 for flagships.
