Offered is „Opera Consonance Linear 1 + 300B PSE Monoblöcke“ by Opera Consonance as second-hand device from the category „Tube-Pre-/Powerampcomb.“ on audio-markt.de - the online market place for high-end. The advert with the number 5742000493 ends on 25.11.2026 at 18:52 o'clock.
This asking price sits well above the typical used EUR market for these Opera Consonance monoblocks, which centers around €1,649 with a 75th percentile at €4,036, so €4,700 is slightly ambitious rather than a bargain. It is not wildly out of line for a clean, desirable tube monoblock pair, but it should be priced with a bit of room for negotiation.
What makes it interesting is the 300B PSE architecture: these amps are valued for that big, textured midrange, excellent tonal color, and enough current to sound more substantial than many classic 300B designs. If the pair is fully healthy, properly biased, and complete with tubes and accessories, it can be a very appealing buy for someone chasing the Opera Consonance sound. At this price, though, buyers should confirm service history, tube condition, and any transformer or hum issues before paying up.
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.
