Description :
The B&K ST-140 is detailed, beautifully sweet and airy at the top, capable of reproducing remarkable depth and spread, and all that with a truly authoritative low end that can compete with the best. Though it is only rated at 105w/c, the ST-140 packs the dynamic punch of a far more powerful amplifier. Still, it does not deliver the beef that a 200 watter amplifier can do. Those last vestiges of control and impact at the extreme bottom are missing, it can't make most speakers shake the walls the way a truly high-powered amplifier can. Anyway, the amplifier is not meant for playing loud headbanging music in the first place. Where it excels in its ability to reproduce low-level information particularly from cds. The listener is able to hear things like very soft bass drum beats or those quiet cymbals in the background distinctly. The B&K ST-140 is a mosfet amplifier. Hence its sound is tubelike. It sounds mellow, rich and has a tendency to soften detail so it won't be harsh. Overall, it's one of the best amplifiers within its price range.
