NAD C 658 Preamplifier & DAC With BluOS Streaming

The NAD C 658 is a Preamplifier and Digital Audio Converter with BluOs streaming capabilities. BluOs is a music management software that allows users to stream and access music on any device within your home network, allowing users to project audio using a smartphone, tablet, or controller. This powerful preamp helps audiophiles upgrade their sound system for the 21st Century by fulfilling the roles of a network streaming device, digital audio converter, and a standard preamp, all in one. This creates a highly controlled and balanced sound, in one neat, cost-effective package.

High Resolution in Every Detail
Most NAD components have been High Res for 45 years with very wide bandwidth, low distortion, and ultra-low noise. We just never had High Res source material to play. With High Res digital recording and streaming, combined with advanced technology like MQA, record companies are opening their vaults and releasing Studio Master Quality recordings. MQA decoding is available through BluOS Streaming content. The C 658 is pure High Res from input to output and features the ESS Sabre 32bit DAC , one of the best performing DACs on the market today with its 118dB Dynamic Range and incredibly low jitter spec. All preamp functions are executed in the digital domain including the same wide range non-truncating digital volume control used in our Masters Series components. This offers an incredibly short analog signal path that, rather uniquely, is identical for all volume settings. Sophisticated active power supplies provide super clean voltages to all circuits to keep noise and distortion at the edge of measurability.

    Good Fit for 2025 Honda CR-V EX-L
    Very happy with purchase. Fit like a champ. Be prepared to work to change the engine air filter. It is more about Honda's design the the filter itself.

    Very durable and quality produced.
    These filters seem very durable and quality made. The air filter looks exactly and feels exactly the same on the factory filter and very easy to replace. The cabin filter was also very easy to replace. This cabin filter feels a lot heavier and higher quality than the factory OEM. Be sure the rigid sides of the filter will fit on the left and right side when installing. If you try to install the filter with the information written on it facing out, then the cover will not fit properly. When the filter is in place correctly, the cover will be easy to put back in place. Both filters seem very durable and quality made.

    Perfect fit
    I started changing my own filters about 10 years ago when I realized how much I could save, and how incredibly UNcomplicated it is. Anyone can find super easy instruction and videos on YouTube. Obviously some cars differ, but I've yet to find one that isn't as easy as replacing batteries in a remote. These filters are the exactly same size, and are made from good quality materials that are equally as good as the OEM filters I pulled out of my 2025 Honda CRV Gas vehicle. They're wrapped in plastic, so they're as clean as an be when you get them. It literally takes less than 10 minutes to switch out these filters, so you're saving a bundle by doing it yourself! Compared to having a dealer do it, this is a super great value, as they not only charge for labor, they probably charge twice as much for the filters themselves. So far, I have had any issues with air flow, and have not gotten any weird warning signs, so clearly they're functioning in the same way the dealers parts do. I mean, they look and act just like the parts already in the vehicle, so I don't expect any issues.

    Easy DIY replacement
    This engine and cabin air filter kit was an easy and worthwhile replacement for my vehicle. Both filters fit exactly as expected and matched the originals in size and shape. Installation was quick and straightforward. The cabin air filter slid right into place, and the engine air filter seated properly with no gaps or bending. Airflow immediately felt improved, and there were no warning lights or fitment issues after installation. The filters appear well made and sturdy, not flimsy or overly thin. It’s convenient having both the engine and cabin filters included in one kit instead of purchasing them separately, especially for routine maintenance. If you drive a compatible CR-V or Civic and want a simple, cost effective DIY replacement, this kit does the job well and saves time.

Overall, a reliable and practical kit for anyone looking to maintain their vehicle’s performance and improve interior air quality.
