At USD499 for a 10ft Acoustic Zen Tsunami III, this strikes me as a fair ask on the used market—right in line with typical pricing for clean examples. New retail hovers around USD450 for shorter 6ft lengths, and I've seen comparable used 10-footers go for USD400-550 depending on condition, so no steal but not overpriced if it's truly very good shape.
Before biting, verify the terminations for oxidation or loose pins—common on these 6N copper builds after a few years—and confirm the stock plugs are intact, as swaps can alter the warm, dynamic sound signature. Ask for close-up pics of the strain relief too; early Tsunamis had occasional flex fatigue there.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Acoustic Zen: Brand Overview
Acoustic Zen Technologies was founded in 2000 by legendary design engineer Robert Lee, establishing the company in San Diego, California. From its inception, the brand has pursued a focused mission: exploring acoustical behavior and sonic transmission to develop innovative cable and loudspeaker designs grounded in advances in materials research and precision engineering. Products are assembled in San Diego using a combination of domestic and imported components, reflecting the company's commitment to American manufacturing standards.
The brand is primarily known for high-quality audio cables and loudspeakers. Acoustic Zen's cable portfolio encompasses interconnects, speaker cables, power cords, and digital cables—all hand-manufactured in California. The loudspeaker line complements this focus, with designs engineered to deliver precise musicality, extraordinary sonic dynamics, and accurate soundstage reproduction. This dual emphasis on signal transmission and speaker design reflects the founder's deep expertise in cable acoustics and system integration.
Acoustic Zen occupies the high-end boutique segment of the audio market, positioning itself as a premium brand for discerning listeners who prioritize sonic accuracy and component synergy. The company's philosophy—expressed in its motto "Music… No compromise!"—appeals to audiophiles seeking uncompromising sound quality rather than mass-market convenience.
