CS-315S CD Receiver Shelf System

Emitting the Sweetest, Sharpest Audio from a Solid-Looking, Compact Unit

The biggest challenge for compact audio systems is to take any music genre and reproduce a detailed, balanced audio output. If we judge the CS-315 CD receiver system on that basis alone, we have a winner. Anchored around Onkyo’s Wide Range Amplifier Technology (WRAT), the CS-315 excels in revealing the nuance of CDs or MP3 tracks recorded to disc. Another outstanding option is to team it up with Onkyo’s RI Dock for the iPod® to bring audio fidelity to all digital music files stored on your PC. Looking as good as it sounds, the CS-315 is enhanced by its striking front aluminum panel and vibration-reducing build. Don’t forget its versatile mobility—this system will easily slot into most spaces that you choose. Forming a competent audio chain with the distinctive D-N7BX 2-way, bass reflex speakers, you can expect the CS-315 to create all the right impressions wherever you place it.
