Description :
These Restek Extract Mono power amplifiers have a build quality that would put most manufacturers to shame. There is also a musicality that transcends the normal expectations of mono's at this price point. The Extract proves to be remarkably neutral and transparent. When used with valve electronics, the Extract imparts a touch of cool to the sound, especially vocals. It is easy to detect a leaner portrayl than either all-valve system offered. But there are surprises - the Extract produces richer, warmer bass than one's prejudices may anticipate. Despite the rating, the Extract does not suggest the sort of power nor the dynamics of a 180w/c amplifier. It does not run out of steam and you have to hammer them to detect even mild compressions and restrains. The Extract is about refinement and comportment. It positions sound with precision, each with its own space. When down to brass tacks, the Restek Extract does the "German" characteristics with transients and percussive attack. At the frequency extremes, the tranients are tight, deliciously fast and well-controlled, with realistic decay, again benefitting material of a rousing nature.
