CD Hi-Fi Mini System

High End Audio Technology in a Compact System

Onkyo’s proven Wide Range Amplifier Technology concept—along with upgraded Three-Stage Inverted Darlington Circuitry and VLSC™ noise-canceling technology—lies at the very heart of Onkyo’s premium hi-fi separates range. The good news is that this same technology is now powering selected compact models such as this one. Combined with the symmetrical layout of the left and right channels and an audiophile-grade 192 kHz/24-bit DAC, distortion is all but eliminated and your music is brought to life. Hear your cherished albums played back with the sort of depth and clarity you might expect from a high-end system. With the CS-555, you can spin CDs or listen to radio, plug in an iPod or flash drive to the USB port, or enjoy the iTunes library on your PC via 96 kHz/24-bit digital inputs. Our latest bookshelf loudspeakers feature N-OMF cotton and aramid laminate cones with center -mounted bullet equalizers to minimize vibration. These speakers smoothly handle phase-matched and boosted bass without obscuring the m id-range frequencies. Robust construction and a quality finish reflect the premium audio technology inside, all in system everybody can afford.
