IWISTAO Earphone Amplifier HIFI Solo with Bluetooth 4.0 CSR8670 32-bit DAC AK4490 Hardware Decoding Optical Inputs APT-X

After the Bluetooth decoder with hardware decoding hit market, we also have developed an earphone amplifier with  Bluetooth 4.0 CSR8670 APT-X, 32-bit DAC AK4490 Hardware Decoding, and Optical Input.

This is a Bluetooth decoder with Bluetooth 4.0 CSR867 and DAC AK4490. The Bluetooth 4.0 version CSR8670 implemented digital signal transmission thought wireless function, the digital to analog conversion of audio output used a professional decoder chip AK4490 to play that the digital signal is decoded into an analog audio signal, and finally OP amplified the analog audio signal and output it.

At the same time, the unit is compatible with optical input, optical input devices can be connected to any other optical fiber output, such as televisions, set-top boxes, projectors, DVD player, CD player, sound cards and other digital computer.

Are you afraid that there isn't enough power for tube amplifier?

Are you afraid that there isn't enough power for tube amplifier?

Sometimes audiophiles are afraid that there isn't enough power for tube amplifier? Now, you don’t be afraid of it. If there is a tube amplifier with output power up to 2 x 50W, that will be ok.

It is a mono-block integrated tube amplifier with 2 x 50W high output power with high cost effective, which is made of pure tubes, adopt 2pcs 12AT7 plus 2pcs 6N8P to drive 2pcs FU13, and its recrifier adopt tube 5Z4P.

Tube FU13 belongs to antique one and is equeal to tube 813, which is a direct thermal beam shot tetrode with thorium tungsten cathode, graphite anode. In the radio equipment, it can be used for the oscillator power amplifier tubes, and its using frequencies are up to 30MC. When it is used as a power amplifier (such as Class AB), its output power is up to 300W or above, it is high reliable, excellent linearity, and not only does it perform tigers’ roaring and thunder exhaustive, but also can perform thin piano voice with detailed and delicate, it is the master of tube amplifier.

FU13 sound is very good, power and life are outstanding, air sense and sound field is far better than with that cannot be compared, you may not want to listen to small power output tube after listeningFU13.Due to its high power output, it can drive high power speakers that tube amplifierwith lower output can't drive.It is the first choice to drive low-sensitivity, high-power and high-end speaker.

For example, when making or DIY tube amplifier, often the holes are opened on the top plate, frankly to say, this job, if without the special equipment to do, it may be a difficult task. Or you want to make the holes on a pure copper, which is more difficult to complete.

However, these seem more difficult to do, now it can be more easily accomplished. We now introduce such a customized service to solve the problem that quantity from one piece.

You just need tell us your requirements with your drawing, we may accept 2D or 3d format, CAD (2D) format drawings like as dwg, dxf, pdf include parts precision tolerances, surface treatment and other special requirements or processing equipment. CAD drawing format; 3D model formats include Sldprt, step, igs, stp, x-t, prt. And, parts’ material may be aluminum, copper, stainless steel, or plastic.

Through pre-sales communication, we have an offer for you. After you complete online payment, we quickly complete your order until delivery.
