OAD Ultrafidelity UF1 Power Amplifier 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 signal non-l
Against the recent AUD comps, A$2,950 sits a touch below the A$3,005 median and under the A$3,037 75th percentile, so this reads as a fair-to-good buy rather than an aggressive ask. It’s close enough to the center of the market that I’d view it as properly priced, with a small edge to the buyer if the unit is clean and complete.
The appeal here is getting a well-regarded piece of OAD/Ultrafidelity kit without paying top-of-market money. If it’s in honest working order, that’s where the value is: these are the kinds of listings that reward a buyer who moves on a tidy example with original packaging or accessories. With condition unknown, I’d just want clear confirmation of functionality and cosmetic state before committing.
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.
