Our Work

The EL84/4 from Lyrebird Amplification. Our first tube integrated amplifier, designed and hand made in Australia! Available for demonstration in South Australia, Queensland, Victoria and soon Tasmania and ACT/New South Wales

"This is a smooth-sounding amplifier that makes listening to music enjoyable and pleasurable. It is not meant to be an analytical tool to dissect recordings, but rather, it’s about letting music flow in an effortless and graceful manner. It conveys the emotional intent of music performances and draws the listener close."

01

Design

Circuit design and installation by a Soviet trained technician with over 50 years of experience, right here in Adelaide, South Australia. Every individual component is tested before use to ensure it meets the required specification, with tightly matched power tubes understressed for long life and reliability. We source as much as possible from Australian manufacturers or suppliers.

02

Sound

Crystal clear high frequencies, surprisingly impactful bass and that classic sweet EL84 midrange. Able to drive even lower sensitivity speakers with authority and finesse. Try it with your speakers and let your ears be the judge, as they are the only ones that matter.
