amazon Nuforce Air DAC reviews
Although the world is gradually digital but in the field of audio, analog is still dominant. A system of cumbersome equipment, space-time, complex connections with tangled strings of wire and a lot of time, money to mix well may have become common in the audiophile world. However, there was a lot of people who believed in the superiority of digital technology and they started replacing their bulky analog sticks with smaller, more versatile digital devices. Nuforce is one of the early device manufacturers to recognize the trend and market with innovative technologies such as Air DAC.
The NuForce Air DAC debuts at CES 2012. It’s a pretty small device that’s even smaller than Apple’s Airport Express audio output jack. Plastic housing made entirely of plastic with simple and effective disassembly. The machine uses external power 5V level through a rectifier adapter. Comes with a USB Wi-Fi transmitter to connect to ultra-compact computers. In addition, there is another version with iTX communicator Apple uses to connect to iPhone, iPad, iPod.
The NuForce Air DAC’s technological highlights are its superior wireless capabilities using SKAA technology from Eleven Engineering, a Canadian manufacturer of Wi-Fi transceivers used in the audio industry. St. Based on the HPX Compression Data Transfer Protocol, a Wi-Fi player connected to an Apple computer or device will encrypt and compress the original audio data from 16 bits to 5 bits and transmit to the set. Receivers through Wi-Fi waves. The receiver will do the task of decompressing, moving the 5 bit data to 16 bits and returning the original audio data. By compressing such data, the transmission of audio data files over a Wi-Fi environment becomes simpler, with no interruptions or muting, as is common in other devices. In order to ensure the quality of compressed sound, Eleven Enginerring uses a number of special techniques to maintain extremely low latency and the THD + N (combo distortion and noise) levels are comparable. Comply with the specifications of the standard CD. Another noteworthy point is that although it operates on the 2.4 GHz common frequency but due to the use of the WFD data transmission protocol, SKAA’s Wi-Fi technology is completely free from conflicts with other Wi-Fi sources. For streaming device players, this is a very important point.
Using SKAA technology, Air DAC main unit can be connected with 4 Wi-Fi players simultaneously. As such, the Air DAC can play the role of the center of the audio system, easily connected to multiple sources such as computers, iPhones and iPads.

The inside of the Air DAC is quite simple. The main part is the SKAA audio decoder attached to the Wi-Fi antenna of Eleven Enginerring. The audio signal after being decoded and restored to the original digital format will be transferred to AKM4426 decoder IC of Akasi Kaisei (Japan) for conversion into analog signal. The AKM4426 is a new 24-bit DAC that is compact, yet powerful enough to deliver high-definition audio reproduction. The audio signal output at 2Vrms and output directly to the RCA port without the capacitor. The circuit is quite compact and uses maximum components to reduce the size, which gives the shortest possible signal line.
Connecting the Air DAC to your PC is simple, no need to install, set up Wi-Fi parameters. Simply plug the Wi-Fi player into the USB port, the computer will automatically recognize the device.
Using the laptop as a source, connecting the Air DAC to the digital amplifier, the NuForce Icon 2 gives the AKG 701 headphone signal, using the Foobar 2000 software to test with some of your favorite music, this system delivers superior audio quality. Exceeds the investment and can completely satisfy the difficult ears. The sound of NuForce Air DAC is quite detailed, solid and dynamic. The sound of hard-to-reproduce musical instruments like Piano, Violin sounds pretty good.
Continuing to test the Air DAC connection with a Marantz old midrange receiver and bring the sound to the pair of Dynaco speakers are relatively difficult to pull, Digitize recognizes the sound quality of the NuForce Air DAC is not much inferior to the top CD Arcam 72. Although the Arcam CD72 is a relatively good CD player, it sounds pretty impressive, but compared to the tiny NuVorce DAC with the same recording, the Arcam CD72’s outstandingness is not that great. Through this experiment, it can be seen that this inexpensive device can completely replace a midrange CD player, keeping sound quality at a hifi level which reduces a lot of cumbersome inconvenience.
