Offered is „CTH-8550 Mk2“ by Dartzeel as exhibit from the category „Transistor-Fullamp“ on audio-markt.de - the online market place for high-end. The advert with the number 5989613173 ends on 12.10.2026 at 10:40 o'clock.
The timing is favorable here because this is an established, endgame-class integrated rather than a current-generation model, so the question is really about value and condition, not chasing the newest thing. At €28,000, it is well above the typical used market for this model: versus a median of €13,270 and even the 75th percentile at €20,840, this asks for a clear premium and reads as ambitious rather than fair.
That premium only makes sense if the unit is exceptionally clean, complete, and provenance-rich, because the CTH 8550 is prized for its grip, authority, and very low-fatigue presentation, with a big, spacious, controlled sound that has kept it collectible. If it has original packaging, full accessories, and strong service history, it is still a serious piece for a buyer who wants one of darTZeel’s most respected designs; at this price, though, I’d want evidence of extraordinary condition or rarity to justify stepping well past normal used levels.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
darTZeel: Swiss Precision Engineering for Discerning Audiophiles
darTZeel Audio SA was founded by Hervé Delétraz in Switzerland, with the brand name itself an anagram of the founder's surname. The company emerged from a philosophy rooted in humanistic design principles, viewing music as a medium for soul expression and spiritual development rather than mere entertainment. This foundational ethos has guided the Geneva-based manufacturer's evolution into a respected name in high-fidelity audio, with the iconic NHB-108 monoblock amplifier first presented in New York in 2002 establishing the brand's early reputation for excellence.
The brand is primarily known for reference-grade amplification, including both monoblock and integrated designs that have garnered universal acclaim from professional reviewers. Beyond amplifiers, darTZeel has expanded into digital audio with innovative products like the LHC-208, a "danalogue" integrated unit combining streaming, DAC, and amplification capabilities with support for high-resolution formats up to DSD256. The company's manufacturing approach emphasizes meticulous CNC-machined aluminum casework and sophisticated assembly, with products instantly recognizable by their distinctive industrial design.
darTZeel occupies the ultra-premium, boutique segment of the high-end audio market, positioning itself as a reference-quality manufacturer for discerning collectors and serious enthusiasts. The brand's reputation rests on uncompromising engineering, limited production runs, and a commitment to sonic purity that has made its components aspirational within audiophile circles. Recent expansion into North America through darTZeel America Inc. signals the brand's continued growth while maintaining its exclusive positioning in the luxury audio landscape.
