OAD Ultrafidelity UF-1 Power Amplifier Custom 4 channel power amp in one box from Melbourne’s own respected Jon D’Sensi. Originally two of these built in 2022 for a LinkWitz loudspeaker project which did not go ahead. I grabbed one of them so I could bi-amp the Osborn Titan speakers. (Padma preamp, also for sale in separate ad, has simultaneous parallel RCA and XLR outputs which both feed this power amp.)

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.
