Chatting to Andrew Hutchison from Dellichord and Brad Serhan from Serhan Swift, Jon De Sensi from OAD Ultrafidelity tells all about his Australian made cutting edge HiFi amplifiers.
OAD Ultrafidelity was founded in 2015 by Jon De Sensi. Operating out of his workshop at home, he developed unique design prototypes of a fully discrete Class A preamplifier and Class AB power amplifier.
In 1990, he started Music Labs whilst working for the Department of Defence as a civilian engineer and later re-designed parts of Australia’s weather radar by replacing, by then, the unreliable vacuum tube designs with solid state designs for superior performance. Music Labs manufactured one of the best and most technologically advanced DACs the world had seen at the time. Preamplifiers and Power Amplifiers with unique designs were also part of the line up.
The current model Padma preamplifier sports a fully CNC remote control and chassis of premium grade aluminium, ensuring an inert and stable base featuring revolutionary volume control and dual mono layout. The current model Vajra amplifier is also a fully CNC premium grade aluminium chassis and features the world’s first known use of Power Supply Slit Foil Electrolytic Audio Capacitors.
The team discuss the Stereonet HiFi & AV Show in Melbourne 2024 where Jon De Sensi will once again demo these “staggeringly” amazing products and the how and why of these spectacular Australian made HiFi products.
