This is a fair ask, sitting almost exactly on the recent used-market median of £1,210. At £1,231, it is well below the £1,459 75th-percentile mark but not the bargain territory below £1,144, so value depends on condition, provenance, and completeness.
The SDA-2400 remains a particularly capable power amplifier: compact, cool-running Class D design, substantial output of 200W per channel into 8 ohms and 400W into 4 ohms, plus balanced, single-ended, optical, and coaxial inputs. Its clean, powerful presentation and unusually flexible connectivity make it useful in both stereo and AV systems, while signal-sensing standby and 12V triggering add convenience. At this price, a clean example with the rack kit and original accessories would be a sensible buy; otherwise, modest negotiation would be reasonable.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Lyngdorf Audio was founded in 2005 by Danish audio innovator Peter Lyngdorf, who brought decades of industry experience to the venture. Lyngdorf's career in high-fidelity began in 1975 as a distributor of home entertainment components, followed by the establishment of HiFi Klubben, a Northern European retail chain, and the creation of DALI (Danish Audiophile Loudspeaker Industries) in 1983. This heritage of audio entrepreneurship and technical expertise informed the company's mission to achieve absolute perfection in sound reproduction through advanced research and development.
Lyngdorf Audio specializes in high-end digital amplifiers, preamplifiers, and surround processors built around proprietary technologies including the Equibit digital amplification system and RoomPerfect room correction software. The company is known for pioneering fully digital amplification and for integrating sophisticated digital signal processing into premium audio systems. Their product philosophy emphasizes the transformation of digital audio data directly into optimized speaker-driving signals, eliminating traditional analog conversion stages.
The brand occupies the luxury segment of the high-end audio market, positioning itself among the world's most sophisticated audio manufacturers. This positioning was solidified in 2007 when Steinway & Sons, the legendary piano maker, granted Lyngdorf exclusive rights to develop audio systems under the Steinway Lyngdorf brand name. Today, Lyngdorf Audio operates as part of the broader Steinway Lyngdorf portfolio, serving discerning audiophiles and professionals who prioritize cutting-edge digital technology and meticulous sound reproduction over conventional amplification approaches.
