Hallo, technisch wie optisch sehr gut erhaltene Phonovorstufe im charakteristischen Röhrenklang, mit OVP, Nichtraucher. Folgende Beschreibung aus hifitest.de heauskopiert:
Röhren-Phonovorverstärker (MM/MC) mit passiver RIAA-Entzerrung
Top Röhren-Phonstufe im Reference Design. Verbindet alle Vorzüge einer High-End Röhren-Schaltung mit den Tugenden einer optimalen Phono-Signalaufbereitung.
Das leistungsfähige Netzteil ist ausgelagert um keine Störeinstrahlung auf das NF Signal zuzulassen. Der gesamte MC-Zweig ist über selektierte handgearbeitete Übertrager von großer Bandbreite realisiert.
Die RIAA Entzerrung ist passiv ausgelegt, ohne jegliche Störungen und Einstreuungen auf das Nutzsignal. Handverdrahtet, ohne signalbeeinflussende Lötstellen direkt über die wichtigen Anschlußpunkte.
Das Ergebnis kann sich hören lassen. Reich an Klangfarbe, ohne Dynamik und ultimative Offenheit zu vernachlässigen entführt einen die Reference 40 in bisher nicht gehörte Musikwelten.

At €950, this Opera-Consonance Reference 9.9 monoblock is a clear bargain compared to the obvious alternative: typical European listings for this rare 845 triode amp sit between €1,450 and €1,600, and even a recent used asking price hit €1,999. Ground-truth data from your own database anchors the fair used range tighter: with a median of €885 and a 75th percentile of €917, this €950 listing sits just above the top quartile but still well below international market norms, making it an excellent value for a well-regarded tube amp.
The Reference 9.9 is prized for its lush, midrange-rich sound and the musicality of its 845 triode output stage, delivering ample power with a warm, organic tone that rivals far more expensive amplifiers. At this price, you’re getting a rare, original-owner monoblock in excellent condition with meaningful upside: genuine scarcity in Europe, proven reliability of the 845 design, and a price that rewards patience over chasing inflated overseas listings. This is a buying opportunity, not a caution.
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.
