SPEC RSA-717EX

摘要

Company co-founder Shirozaku Yazaki had been an inveterate hi-fi hobbyist in his spare time, designing and building his own valve-based amplification. This interest informs SPEC'S solid-state Class D amps - like this £3900 RSA-717EX - which aim to recreate the distinctive characteristics of 300B-powered amplification, described by the company as 'Real Sound'. It's the least expensive amplifier in the SPEC range, delivering a claimed 50W/8ohm, and double that into a 4ohm load, figures which our lab tests showed it just about achieves. On first acquaintance, the RSA-717EX impresses with the simplicity of its design and the quality of its build.
