A Night with Hugh Dean, Aspen Amplifier Designer 8pm Wednesday 15th March, visitors welcome. Willis Room, City of Whitehorse Offices Maroondah Highway (Whitehorse Road), Nunawading Melway Map 48 Ref G9 Contact: 9437 1249 The name Hugh Dean is synonymous with the Aspen amplifier range. His kit form amplifiers have won many hearts among audio enthusiasts who appreciate a very high standard of sound. The Maya 200 and the SAKSA 85 amplifiers are a culmination of over twenty years innovative design, starting in 1974 with the Glass Harmony. The Maya was conceived in 2015 with a topology breakthrough, which Hugh will attest has brought huge improvements in speed, bandwidth and clarity. This 200W per channel amplifier comprises four discrete stages: Input stage including a feedback node, Voltage Amp stage, Driver stage, and the Output stage which uses a pair of very large 480 watt MOSFETS. Hugh's primary aim in his amplifier design is very low odd order harmonics. The MAYA avoids phase issues with extremely linear first and second stages. With very low THD, less than 0.025% into 200W and very low noise, the Aspen amplifiers have none of that solid state glare. The amplifiers can be bought as a DIY build from a pair of tested and assembled PCB modules, starting at $930 plus GST for the SAKSA 85, and $2200 plus GST for the MAYA 200. Both units can now also be purchased with purpose built full enclosures. An OPPO 105 multi-disc player will be playing the music, while a pair of classic KEF 105/3s will entertain us with their sound. The 105/3 was the first Reference Series Loudspeaker from KEF to incorporate Uni-Q technology. This four way floor-standing speaker embodies several advanced and unconventional design features for its time. Its bass section drivers are mounted within the cabinet in a double coupled-cavity configuration. The combined output of the two woofers is radiated through a front mounted 6" inch diameter port. The D'Appolito array on the front panel is shared with a pair of midrange drivers and a KEF Uni-Q driver, with a concentric 6-1/2" inch cone and a 1" inch tweeter. Midrange bloom, solid state glare, lifeless sound? None of that with Aspen Amplifiers.
