Ich verkaufe meinen Boulder 866 in der Version mit integriertem Streamer und DAC. Wegen eines Umzugs habe ich künftig nicht mehr genug Platz für die Anlage, deshalb gebe ich ihn schweren Herzens ab. Er wurde immer gut gepflegt und ist in neuwertigem Zustand.
Gekauft habe ich ihn im Januar 2024. Er liefert 200 W pro Kanal und wird über das Stromnetz betrieben. Bedienen lässt er sich über den Farb-Touchscreen oder die Boulder-App.
USB, Ethernet, AES3 und Toslink sind dabei, außerdem unterstützt er AirPlay und Roon.
The 866 is an older-generation model, having replaced the 865, but its integrated DAC/streaming architecture remains highly capable rather than obsolete. At €12,900, though, this example is clearly above your comparable-market 75th percentile of €12,734 and €1,470 above the €11,430 median, so the asking price is ambitious rather than a standout deal.
It remains a serious one-box solution: powerful, exceptionally transparent, rhythmically precise, and able to drive difficult speakers with real authority. The DAC is derived from Boulder’s higher-end design, with extensive digital input and network functionality, while the build quality and removable digital board add reassurance for long-term ownership. Excellent condition helps justify a premium, but at this level the listing needs complete accessories, confirmed software/network operation, and ideally documented servicing; otherwise, negotiating toward the low-€12,000s would make it considerably more compelling.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Boulder Amplifiers traces its roots to the professional recording and broadcast world of the 1970s, when founder Jeff Nelson, a self-taught electronics expert, built mixing boards for studios. In 1984, the company formally launched in Colorado—initially in an old farmhouse near Superior, later relocating to Louisville—with the debut of its rugged 500 power amplifier, prized by engineers for its clarity and durability. Under Nelson's leadership for over four decades, Boulder transitioned from pro audio gear to the pinnacle of home high-fidelity, maintaining full vertical integration in a sprawling 23,000-square-foot facility where every chassis, circuit, and component is crafted in-house.
The brand specializes in solid-state power amplifiers, preamplifiers, and integrated electronics, epitomized by flagships like the 2150 monoblock and 800 Series. Absent from speakers, turntables, DACs, headphones, or cables, Boulder's focus remains laser-sharp on amplification, delivering ultra-neutral sound with vanishingly low distortion—such as the 2150's 0.00036% THD and 1000W output—and peerless signal-to-noise ratios.
Positioned at the apex of high-end audio, Boulder commands reverence among discerning audiophiles for indestructible build quality, cost-no-object engineering, and machined-aluminum casework that sets unmatched standards. As North America's last fully in-house audio manufacturer, it appeals to buyers seeking unflappable performance and heirloom longevity, with prices reflecting its elite status, like $110,000 pairs of monoblocks.
