2019年1月1日 · The C 399 Hybrid Digital DAC Amplifier is the clearest expression yet of NAD’s commitment to sonic excellence and lasting value. Employing NAD’s HybridDigital nCore™ amplification, which until now has been available only on Masters Series amplifiers, the C 399 is the new flagship integrated amplifier in NAD’s Classic Series.

2020年3月17日 · Shame to see quality control or design issues in a brand like NAD. Even if the digital inputs were not broken, the performance of the DAC fails to even match a half decent $9 phone dongle. So despite great feature set, NAD needs to go back to the drawing board and clean up its implementation. Needless to say I can't recommend the NAD C658.-----

2013年5月31日 · NAD isn’t like some manufacturers who will very consistently pick a single DAC chip and stick with it for multiple tasks, preferring to choose what works best in a given situation. In this instance, the DAC is a Burr Brown type and makes use of matching Burr Brown op-amps in the output stage.

2022年5月30日 · This is the review and detailed measurements of the NAD Wireless USB 2 stereo DAC. It is on kind loan from a member and costs around $250. The unit is smaller than it looks in NAD pictures. The transmitter is tiny and not much bigger than a USB charger. It is self powered over USB and gets...

2014年2月27日 · NAD DAC2 Wireless DAC Review The first and most important thing to point out about the DAC2 is that on a technical level, it does exactly what NAD set out to do. It builds on the positive attributes of the DAC1 and ensures you get a foolproof and utterly stable wireless connection between your computer and audio system.

2016年2月13日 · This is a review and detailed measurements of NAD M51 DAC and digital preamplifier. It is on kind loan from a local member. Even though it is still listed on NAD website, other retailers indicate it is discontinued. Looking around, it seems the cost is USD $2000. The unit has somewhat bland industrial design for my taste:

2022年5月30日 · NAD DAC2 uses the same frequencies as WiFi, so its propagation characteristics are the same as Wifi. However NAD DAC2 transmit power is way lower than Wifi, of course then its range is more limited. Note that besides the transmit power level, the propagation range is a function of receiver sensitivity, antenna gains, etc.

2022年5月30日 · I got nowhere: Even the NAD site lacks any information about the RF technology or type or specs. The NAD DAC2' FCC certification shows approval for 2.4GHz band but another source alluding to: "The wireless transmission takes place at frequencies of 2.4, 5.2 and 5.8 gigahertz, and you can access the three channels by using the manual switch…"

2022年5月30日 · That is -- why would someone not use a streamer device with it's own Network interface and SOC processor, and it's own audio interface (Chromecast Audio, WiiM, Node, Sonos Port, et al) controlled by an "App" that turns your mobile device into a remote control -- so you don't need to use the iPhone/iPad as the "streamer" (network interface ...

2022年5月30日 · Connectors are way up there in BOM cost, along with an extra usb receiver chip, some signal switching mux. Really after the chassis and Bare PCB, they are the most expensive components you'll find in a product. I'd rather pay 20-30$ more and have a "one fits all" device, but maybe it's just me.
