Notable as a versatile, properly high-end amp/DAC rather than merely a headphone volume control. At A$1,999, this is essentially a fair market price: it sits just above the A$1,936 median, below the A$2,053 75th percentile, and well above the A$1,359 lower quartile. It is not a bargain, but it is defensible if the unit is clean and complete.
The HDV 820 remains appealing for its refined, low-noise presentation, strong drive for high-impedance headphones, and unusually comprehensive connectivity: USB, optical, coaxial, balanced and single-ended analogue inputs, plus 4-pin XLR, 4.4 mm and 6.3 mm outputs. Its built-in DAC supports high-resolution PCM and DSD, while preamp functionality adds useful system flexibility. At this price, confirm the condition, remote or original accessories, and that every output and input works; otherwise, negotiate toward the median.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Founded in June 1945 by Dr. Fritz Sennheiser in a farmhouse near Hanover, Germany, Sennheiser began as Laboratorium Wennebostel, producing voltmeters and early microphones amid post-World War II reconstruction. Seven engineers from the University of Hannover joined the founder, quickly pivoting to broadcast microphones like the DM 2 in 1946 and the groundbreaking MD 82 shotgun mic in 1956. Renamed Sennheiser electronic in 1958, the family-owned company passed to second- and third-generation leadership, maintaining its innovative spirit over eight decades.
Sennheiser excels in professional and consumer audio, renowned for microphones, wireless systems, and headphones that set industry standards. Pioneers of the first open-back headphones (HD 414 in 1968) and enduring studio icons like the MD 421 and MD 441, they also produce high-end headphones, earbuds, soundbars, and conferencing solutions. While strong in pro audio like mixers and geophysical gear, their consumer focus centers on headphones and wireless tech rather than amplifiers, speakers, turntables, DACs, or cables.
Sennheiser commands a premium position in the hi-fi market, blending mid-tier accessibility with high-end excellence for discerning buyers and professionals. Trusted for reliability and sonic precision, it appeals to audiophiles seeking reference-grade headphones without boutique obscurity, backed by a heritage of technological firsts that sustains its global leadership.
