amazon Nuforce BTR100 reviewsThe trend of media integration on handsets has led to the growing presence of portable music players that do not need to be connected by wires such as wireless speakers, wireless headsets or wireless music players. The biggest market share is still Bluetooth music players. The advantage of this device is that it is small, easy to setup and very popular, able to connect to almost all devices. However, most Bluetooth music players on the market sound pretty bad, mostly due to poor circuit design and cheap integrated DACs. Another reason why Bluetooth music players are unpopular is the perception that Bluetooth transmission reduces the quality of the sound due to the compression of the data. Therefore, only a handful of brave sound makers go in the direction of producing Bluetooth-enabled audio devices for audiophile use. And Nuforce is one such manufacturer.
The BTR100 can be considered one of the cheapest devices in many of the audio equipment manufactured by Nuforce. However, cheap does not mean poor quality. When opening the plastic cover of the device, the circuit inside is done quite carefully and arranged neatly. The main part of the circuit is a DAC using Wolfson WM8524 decoder. A Wolfson WM8804 IC is also receiving signals from the bluetooth receiver to transmit to the decoder chip. The components used on the circuit are all components of good technical specifications. The machine uses 5V power from an external adapter, then through a component that stabilizes the voltage down to 3.3V to supply the entire circuit. A 3.5 mm jack can connect to the headphones and use a pair of wires to connect the amplifier. The machine also has an optical port that outputs digital signals in case of connection to an external DAC or digital amplifier.
To overcome the disadvantages of the Bluetooth transmission method in ensuring sound quality, Nuforce uses Bluetooth connectivity with the AtpX symbol. This is a form of audio data compression protocol with a 4/1 ratio but retains the same specifications as an older CD player (16 bit and 44.1 KHz). This technique also maintains the same frequency and dynamic range of sound as that of a midrange CD player.
Connecting BTR100 to a mobile device for use as a music source is simple. Just turn on the Bluetooth mode on the handset and select “pair” the device with the BTR100 and run the music player software, the audio signal will appear at the BTR100 output. Testing the connection between BTR100 and Samsung Galaxy Note 3, Apple iPhone 5S, iPad and MacBook, the signal is very good at less than 10m. Choose the mode of tripping, stop the post on the phone, BTR100 reception almost instantaneous, no latency as encountered with Wi-Fi connection.

The BTR100 connects to the ampli – speaker for excellent sound quality, beyond imagination for a cheap device. The sound of the BTR100 is relatively detailed and poised, especially in recreating the bass notes. The stage is quite focused and seems to be moving towards the listener. Testing the BTR100 with some of the popular, easy-to-pull headsets such as the Sennheiser HD598, AKG5500, the sound is good, but not as professional as the professional players, but it’s hard to ask for more than one device. Integrate many functions with such price range.
Although it can only bring the level of a hifi device, it is hard to compare with the good readers and can not stand on the same level as expensive wireless devices that play lossless music, $300 can say BTR100 is a bargain for the audio player if you want to have an experience with the source is the phone is used. Collect high-quality digital music, install dedicated music software with multiple tuning modes, and stream music via the BTR100 to the terminal – nothing more. BTR is a 2-in-1 wireless device, both a DAC and a music player. A good circuit board plus bluetooth for audio technology makes the BTR100 fair enough to compete with a midrange CD player, just like Nuforce’s criteria when it launches.
