Offered is „SIA 025“ by Vitus Audio as second-hand device from the category „Transistor-Fullamp“ on audio-markt.de - the online market place for high-end. The advert with the number 5302658597 ends on 12.11.2026 at 12:15 o'clock.
Timing matters here because this is the earlier SIA-025, and the market has clearly moved toward the Mk.II, but the asking price still lands well below recent comparable used listings. At €8,450, it sits under the €10,223 25th percentile and well under the €11,997 median, so this reads as a strong buy rather than a merely fair one.
That’s because the SIA-025 is still admired for its weighty, effortless class-A presentation, excellent tone color, and the sort of control and refinement that make it easy to live with for years. If the unit is clean, fully working, and ideally complete with remote and original packing, this is the kind of price that makes sense for a serious listener who wants top-tier sound without paying the usual used-market premium.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Vitus Audio emerged from Denmark in 1995, founded by Hans-Ole Vitus Nielsen in Herning, where he serves as owner, designer, and constructor under the AVA Group. Nielsen's vision has propelled the brand since its inception, with the debut products launching in 2003 and 2004, swiftly cementing its place among the world's elite high-end audio marques.
The brand specializes in premium solid-state electronics, excelling in power amplifiers, preamplifiers, integrated amplifiers, and digital-to-analog converters (DACs). Their lineup emphasizes reference-grade performance, prioritizing musicality, transparency, and build quality over mass production, with a focus on modular designs that appeal to discerning audiophiles seeking endgame systems.
Positioned firmly in the ultra-high-end market, Vitus Audio commands reverence for its uncompromised engineering and sonic purity, attracting collectors and enthusiasts who demand the pinnacle of hi-fi reproduction. Far from mid-tier or vintage appeal, it thrives as a niche boutique leader, where innovation meets artisanal precision in a competitive global arena.
