Offered is „Reference 5.5 MK2“ by Opera Consonance as second-hand device from the category „Tube-Fullamp“ on audio-markt.de - the online market place for high-end. The advert with the number 9268179177 ends on 27.11.2026 at 06:44 o'clock.
The timing is a little less about generation age than about whether these were built and maintained well, since this is a mature tube monoblock design rather than a fast-replaced model. At €1,900, the asking price sits well above the €954 median and even above the €1,428 75th percentile, so it reads ambitious rather than fair.
That said, this is a respected 845-based single-ended design with real cachet for buyers who want that big, spacious midrange and holographic presentation, and the monoblock format has lasting appeal. If the pair is clean, original, and properly serviced with known-good tubes and the right accessories, there is genuine upside here; if not, the premium leaves less room for maintenance risk than I’d want at this level.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Opera-Consonance, also marketed as Opera Audio, is a Chinese hi-fi brand founded in 1994 in Beijing by Shi Hui Liu, who is also identified as the company’s chief designer and owner. It is one of the earlier international high-end audio manufacturers to emerge from China, and the brand has long emphasized original design and in-house manufacturing.
Its product range is broad and centered on traditional audiophile components: amplifiers, preamps, CD players and DACs, turntables, loudspeakers, and related accessories. The brand has been especially visible in analogue and tube-oriented gear, including turntable systems and valve amplification, alongside digital source components and speaker designs.
In the market, Opera-Consonance sits in the high-end but still boutique tier rather than the ultra-luxury mainstream. It is better known among experienced audiophiles than casual buyers, with a reputation for ambitious industrial design, careful fit and finish, and strong value relative to more established Western rivals. In the U.S. and other Western markets, it remains a niche brand with a cult following rather than a household name.
