At US$15,599, this is a far better proposition than shopping for a lesser new amplifier at the same money: it is a genuine bargain against the Boulder 1160’s recent used market. The price sits well below the US$18,713 25th-percentile figure and roughly US$6,227 under the US$21,826 median, so even with the listing’s sparse condition information, the value case is unusually strong.
The 1160 is a serious, generously engineered power amplifier: 300 watts per channel into 8, 4, or 2 ohms, with substantial current delivery for difficult speakers and a clean, controlled presentation. Its fully differential circuitry, extensive output devices, and networked supervision add to its appeal. Before committing, confirm physical condition, service history, correct voltage, and that the substantial shipping arrangements are sound; otherwise, this looks like an excellent opportunity rather than merely a fair buy.
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.
