The next meeting of the AES Melbourne Section will be on Monday 10th August at 7:30pm
at The SAE Institute Lecture Theatre, 235 Normanby Rd South Melbourne.
Hugh Dean of Aspen Amplifiers (http://www.aksaonline.com) will present on the topic
Designing Practical High End Audio Amplifiers
Hugh will describe the history of his AKSA amplifier design, giving detailed information and methodologies. He will also highlight the importance of establishing an appropriate distortion profile to provide a more realistic merit indicator than a simple THD% figure.
He will challenge the efficacy of the “Vanishingly-small THD Figure” specification approach, offering a different approach to the distortion issue for amplifiers designed to reproduce music.
This should be a most interesting, informative, and thought-provoking presentation.

About Hugh Dean:
Hugh Dean was born in 1951, and attained two Masters degrees after a successful Army Career. His knowledge of analog power amplifier topology and design evolution is more than extensive. Over the past 20 years he has marketed a range of AKSA brand amplifier kits/built units to hundreds of customers worldwide. His design approach using LTSPICE adopts the essential performance criterion of a unique harmonic spectrum which resembles that of the best high end tube amplifiers. AKSA designs are rugged, reliable, broadly load tolerant and competitive with the very best high end solid state designs usually at lower cost. With hundreds sold worldwide, owner testimonials all attest a consistently musical and entirely satisfying listening experience. A Melbourne resident, Dean is married with two grown daughters.
