This is a buyer’s market for this category, and the asking price looks ambitious against the recent used pool: A$1,100 sits above the 75th percentile of A$997, well over the median A$648, so it’s not priced like a quick-turn bargain.
What makes it interesting is the niche utility: a good audio switcher can be a tidy, low-loss way to manage multiple sources without touching the signal chain too much, and these sorts of boxes appeal to system tinkerers who want flexibility. At A$1,100, I’d only lean in if it’s genuinely pristine, fully original, and includes the exact cables/manuals you need; otherwise, buyers have room to wait for a more sensibly priced example.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
System Audio, a celebrated Danish loudspeaker specialist, traces its origins to 1984 in Roskilde, when guitarist and electronics technician Ole Witthoft grew frustrated with the lack of musical realism in prevailing home audio systems. Dissatisfied with the era's bulky, complex, and costly hi-fi speakers, Witthoft crafted his own designs for personal use and friends, sparking a company dedicated to accessible excellence. From modest beginnings, it expanded through Valby in 1994 and back to Roskilde by 2002, embodying Denmark's storied electroacoustics heritage amid a nation of audio innovators.
The brand focuses intently on loudspeakers, blending minimalist Scandinavian aesthetics with high-end engineering for tactile finishes and precise sound reproduction. Their range spans traditional floorstanders and stands to innovative wireless models, prioritizing music's emotional core over gimmicks. While not venturing into amplifiers, turntables, DACs, headphones, or cables, System Audio's speakers deliver studio-like fidelity with effortless integration into modern setups.
Positioned as a multi-award-winning mainstay in the high-end market, System Audio appeals to discerning buyers seeking mid-to-premium tier performance without ostentation. Renowned for bringing listeners closer to beloved music through Danish precision, it holds strong esteem among audiophiles, rivaling peers in a competitive Scandinavian landscape.
