Onkyo announces three new CS compact Hi-Fi systems

CS-N775D blackOnkyo continues to bring excellent hi-fi performance to their compact systems. They have announced three new package systems – the flagship CS-N775D Multi-room Receiver System, CS-N575D Multi-room Hi-Fi CD System, and CS-375D CD Receiver System.

Each one of the new systems blends component-grade musicality with effortless operation. Best of all, this opens the door to people of all ages, especially those less familiar with network audio.

Two network models support Chromecast built-in, DTS Play-Fi, proprietary multi-room distribution for network and analogue audio. The CS-N775D adds AirPlay wireless audio streaming platform. Spotify, TIDAL, Deezer, and TuneIn are integrated together with mobile music and audio on networked media server via the Onkyo Controller app for iPad, iPhone, and Android devices.

The receivers also showcase a new JOG dial and advanced display technology. These will no doubt help everyone find and play music in seconds.

The CS-N775D and CS-N575D feature information-rich LCDs providing visual reference when navigating content. Operation is demystified for listeners that prefer intuitive front-panel control.

CS-N775D Multi-room Receiver System

Central to the CR-N775D concept was development of patented a 3-state Bitstream switching amplification. Onkyo says that this achieves class-beating frequency response, flat linearity, and analogue-like fluency with ultra-wide-bandwidth resolution.

Where conventional switching amplifiers use only two digits (“on” or “off”) to reproduce the sound wave, 3-state Bitstream adds a third digit or “neutral” position. This is to smoothly shape a waveform similar to that produced by an analogue amplifier.

CS-N775DHigh power elicits peak performance from low-impedance speakers, distortion levels vanishing as sound-pressure grows to fill the room with vibrant music. The amplifier excels with quality sources decoded by an AK4490 768 kHz/32-bit DAC from AKM.

With 40W + 40W (4 Ohms, 1 kHz, 10%, 2-channels driven, IEC), the CR-N775D is paired with D-165 2-Way Bass Reflex Speakers. These are fitted with Onkyo’s premium 130mm N-OMF woofer and 30mm ring-radiator tweeter in an MDF enclosure with thick baffle.

Users can stream any music from Chromecast-enabled apps to the CS-N775D and any other supported speakers with Chromecast built-in.

DTS Play-Fi

DTS Play-Fi technology, meanwhile, allows streaming from online services, media server, or device library over 5 GHz/2.4 GHz Wi-Fi via the Onkyo Music Control App.

Furthermore, this tech also connects systems for synchronised music in every room, and can also stream different music to different rooms. Users can easily structure a comprehensive ecosystem that satisfies virtually any need.


Onkyo also includes proprietary multi-room network and analogue audio distribution baked into the Onkyo Controller app. Mirror audio from the CS-N775D in other rooms or configure speakers for grouped playback.

AirPlay is also included to share audio from supported applications, such as iTunes, from mobile devices and PC over Wi-Fi. There is, of course, Bluetooth which offers a versatile wireless connection to almost any device.

Music servers

In another first for Onkyo, portable HDDs can function as a music server for the CS-N775D when connected to a USB input.

Listeners can also download music to PC and copy the files to the HDD via the home network. File playback includes 192 kHz/24-bit FLAC, ALAC, and WAV as well as Direct DSD 11.2 MHz*6, DSD 5.6/2.8 MHz, and compressed audio formats.


Further entertainment is served via FM/RDS and DAB+ tuners, front-loading CD player, 192 kHz/24-bit-capable co-axial and optical digital audio inputs, and line-level input.

IR input/output and subwoofer pre-out join gold-plated speaker posts on the rear panel.

CS-N575D Multi-room Hi-Fi CD System

The CR-N575D receiver generates 20W + 20W (6 Ohms, 1 kHz, 10%, 2-channels driven, IEC) for enthusiastic hi-fi sound.

Original switching amplification features Optimum Audio Control DSP tuning, which integrates amp and loudspeaker characteristics for best performance. The efficient switching technology delivers high power for increased speaker sound-pressure and a wider sound-field.

CS-N575D angled silverWith processing and amplification performed in the digital domain, accurate detail resolution is possible across a wide frequency bandwidth. This produces rich, nuanced vocals, buoyant bass, and unstrained articulation of high frequencies.

Each supplied D-075 2-Way Speaker includes a 130mm pressed pulp-fibre woofer and 25mm soft-dome tweeter in a thick MDF baffle. Vibrant stereo sound is projected from a compact footprint.

The receiver features Chromecast built-in, DTS Play-Fi, Onkyo multi-room audio distribution. You also get the same on-demand music services as the flagship model with support for Onkyo Controller, Bluetooth streaming, FM/DAB+ tuners, and LCD with JOG dial.

The CS-N575D supports HDD playback via USB input and full support for Hi-Res Audio including Direct DSD 11.2 MHz.

Connectivity includes USB inputs, 96 kHz/24-bit coaxial/optical digital inputs, line-level input/output, IR input, subwoofer pre-out, and headphone jack.

CS-375D CD Receiver System

The CS-375D carries the same premium switching amplification with Optimum Audio Control as the CR-N575D receiver. The system serves magnificent sound with natural verve. Onkyo boasts that it beats class rivals purely on this alone.

All this is packaged in a system that offers great value.

You also get the JOG dial for easy operation, as well as coaxial digital and line-level inputs to route TV sound through the system or connect a media player for easy network audio. FM/RDS and DAB+ tuners add further value.

CS-375D blackBluetooth technology assures quick and stable wireless connection, the system powering up when detecting an incoming stream from an audio application.

Furthermore, it offers USB audio from flash-memory devices, and the CD player reads CD-R/CD-RW and well as MP3-encoded discs.

Additionally, the same high-quality D-075 speaker system as the CS-N575D completes a package that’s pitched at those seeking the best-sounding compact system on a modest budget.


Finally, to round-up, all three systems encourage families to make music a part of everyday life. Offering separates-level performance in unobtrusive dimensions, and cleverly integrating app-based audio and sharing it around the home. The new CS Series outshines in every respect.
