Product Details

Onkyo Silver Integrated Digital Stereo Amplifier, Model A9555SIL

Digital amplification enables significant power efficiency savings and supports smaller, more compact designs—obvious benefits for today’s home lifestyles. However, at Onkyo, we believe that these benefits should not come at the expense of the most important consideration: sound quality. With the A-9555 integrated digital amplifier, sound quality takes precedence over all else. By using Onkyo’s exclusive Vector Linear (VL) Digital technology to remove any spike noise before it introduces errors into the inversion timing, it is possible to get a highly accurate analog-to-digital conversion. Also, at the heart of the A-9555 is a Pure Stream Power Supply—essentially a large power transformer—that ensures that you always have the on-demand power for the clarity and detail of a range of musical genres. By integrating the fundamentals of audio amplification with the potential of digital amplification, the A-9555 is a revelation in superior audio reproduction.
