Sound of nature -- Wistao NFC Bluetooth 4.0 HIFI Bluetooth acoustics hit market, wireless HIFI come from here!


Sound of nature -- Wistao NFC Bluetooth 4.0 HIFI Bluetooth acoustics hit market, wireless HIFI come from here!


It has been used in high-end Bluetooth stereo that CSR's Bluetooth 4.0 chip with apt-x Professional codec technology widely, and become a trend in wireless HIFI acoustics. Recently, Wistao Technology released a pair of separated HIFI tube Bluetooth acoustics, and two HIFI Bluetooth speakers which based on CSR Bluetooth 4.0 technology and apt-x decoding all. For both Bluetooth speakers, one is a 2.0 channel stereo HIFI Bluetooth speakers, the other is an integrated desktop HIFI tube Bluetooth acoustics.

These HIFI Bluetooth acoustics are two-channel stereo output, adopt CSR Bluetooth 4.0 technology, and support CSR apt-x professional decoder. All cabinets of HIFI Bluetooth speaker is made of high quality MDF (medium density fiberboard); separated HIFI tube Bluetooth acoustics and integration Desktop HIFI tube Bluetooth stereo, whose preamplifier is made of tubes, and their out power are from 2 X 25W to 28W, fully to meet the demand for enjoying music indoor . Cabinet of speaker are designed and tuned by professional engineers and its circuit is completed to adjust by the UK experienced engineering team in order to make sure it more perfect sound quality, let you enjoy HIFI music. Overall feeling is, that surging tide of audio sound, powerful bass, treble highly resolving power, and human voice being rich sense of the scene, accurate sound field positioning, like a "good voice" singer standing in front of you…... In addition, all models above can be built-in NFC chip as an option, so you don’t need to open the Settings menu of smart mobile terminals, and can quickly achieve Bluetooth pairing, greatly enhancing users’ experience.

And if you download and install a lossless music formats player (such as WMA, AAC, FLCA, AIFF, etc.), it will achieve to reproduce HIFI music with a wireless way .Due to adopting Apt-x professional audio decoding technology, its performance will be strived for further improvement to compare with normal speaker, or even pull away, and easily to achieve CD-quality sound.

Main characteristics of CSR APTX audio codec technology is low-power, low-latency (when sampling frequency is 48 kHz, it is less 2 ms), fault tolerance (When BER <1:10,000 perfect to regenerate), high-quality, etc. Its high sound quality is main reflected in frequency response range of 20Hz-22kHz, supporting 16bit, 24bit audio, sampling frequency up to 48kHz, dynamic range in 16bit> 92dB, 24bit > 120dB, but sound basis of dynamic range is 96dB for minimum sample rate of 44.1kHz CD-quality of 16bit stereo (entry-level quantization bits). From comparison above data of apt-x, we can draw a conclusion that it is not difficult to see how it reach and exceed t CD quality. It can break through the barriers of bandwidth with Bluetooth connection to transmit excellent reproduction of stereo sound with CD-quality stereo audio. At the same time, CSR provide Clear Voice Capture (CVC ®) technology for high-end Bluetooth stereo acoustic echo and noise cancellation. (More specific features of apt-X audio decoding technology, please see "Bluetooth 4.0 version of the CSR series chip key features of" and "CSR Bluetooth 4.0 and apt-X high-fidelity audio technology").

Perhaps, these figures may sound so professional that you are boring, ok, let look at evaluation to apt-x from manufacturers such as Nokia, Samsung.
Nokia's evaluation it that apt-x audio codec technology of CSR can break through the barriers of bandwidth, with CD-quality stereo audio through a Bluetooth connection to a wide variety of consumer electronics applications Transfer ".
Samsung's evaluation is similar, CSR apt-x technology demonstrates superior stereo audio Bluetooth connection quality, and its completed audio frequency bandwidth consistent complies with high-fidelity performance.

What are you waiting for still? Why do not you work together with us to enjoy this fantastic wireless HIFI music!



We also have another Bluetooth 4.0 Speaker except the above, this is portable Bluetooth 4.0 Bluetooth speaker with NFC and also support apx-t, the link is below:

Tube Amplifier Hybrid HIFI 6N3 Preamplifier 2 x 15W

Tube Amplifier Hybrid HIFI 6N3 Preamplifier 2 x 15W



It is a HIFI hybrid tube amplifier, which pre-amplifier is made of tubes 6N3 and power stage adopt TDA1521A IC power amplifier. 

Workmanship and choice of materials are very cautious, used a double-sided fiberglass PCB, low loss transformers, excellent vacuum tube and full brushed aluminum casing. 

Sound authentic, no deliberate modification, nor omission, is a good partner of full-range speaker.

IWISTAO HIFI 2x100W Bluetooth4.0 Power Amplifier Audio NE5532 Preamplifier 2SA1941/2SC5198 APT-X

 IWISTAO HIFI 2x100W Bluetooth4.0 Power Amplifier Audio NE5532 Preamplifier 2SA1941/2SC5198 APT-X


This is a HIFI Bluetooth Music Amplifier that adopts To shiba 2SA1941 and 2SC5198 transistor, and support Bluetooth 4.0, its output power is up to 2x100W. There is two modes of signal input, Bluetooth and 3.5mm AUX line-on two modes, you can select by yourself.


IWISTAO HIFI 2x100W Bluetooth4.0 Power Amplifier Audio NE5532 Preamplifier 2SA1941/2SC5198 APT-X from IWISTAO HIFI MINIMART1 on Vimeo.


The HIFI Bluetooth music amplifier is designed as class AB with full structure of separated components and parts, and scientific, rational PCB layout and strict sound adjusted so that it performs distinctive sound. And add distortion servo circuit in the circuit design, so when large dynamic come, its performance is leisurely, unhurried. Meanwhile, its amplified circuit adopts NE5532 as a preamp, and T oshiba tube as power amplifier stage, these two parts complement each other. In addition, it builds amplifier speaker protection circuit inside to protect your speakers. Cooling system is made of blackening treatment process of heat sink, and a fan that connected with heat trace wire to the heat sink with forced cooling.


Brushed aluminum panels, black metal housing, it is noble and elegant. It is adopted that transformers toroidal with all copper, high efficiency and low leakage, which provides powerful current, thus providing better, more pure sound. As a HIFI Bluetooth desktop amp, front panel has a third selection for signal input, Bluetooth / PC / AUX; and there is tremble and bass knob for tone adjustment and AUX input jack.


Also there is bass and tremble adjustment knob on the front panel.
