Best Chinese Tube Amplifiers in 2024

Equipped with two 6K4 vacuum tubes, this amp produces warm and soft sound while eliminating digital noise to enhance your Hi-Fi experience. In addition, the default tubes can be replaced with other supported models due to the removable design.

It supports wireless sound transmission via Bluetooth 5.0, meaning that any Bluetooth-supporting device – smartphone, laptop or tablet – can be easily connected to the amplifier.

However, this amp is not very popular among customers, which explains its low ranking.

The idea of buying a Chinese amplifier can be intimidating at first. After all, the device is considered a part of a serious sound system. But if you just want to try it out, or need something small to complement your desktop setup, then this mini amplifier by Nobsound is a perfect option.

With a 3.5 mm AUX output, you can connect passive/active speakers, an amplifier (using this one as a stereo preamp), or a headphone set, making it a perfect choice for a PC system.

The amplifier uses a 6N3 vacuum tube, known for its ability to soften harsh digital sounds, providing warm and clear Hi-Fi sound.

The only reason this amplifier is ranked lower is that it’s not sufficient to significantly improve sound quality – you’ll need something more powerful for that.

While not necessarily ‘affordable’ – after all, this amplifier costs more than $150 – this device is loved by customers due to its impressive output power and low-frequency output. To amplify and improve the sound quality, it uses two GE5654 vacuum tubes, delivering intense Hi-Fi sound with soft deep basses.

In terms of connection to devices, besides Bluetooth 5.0, it supports Stereo RCA and MM Phono inputs, allowing you to use X1 as a tube amplifier and an MM phono amplifier. In addition, you can easily switch the input signal thanks to the input selection option. To put it more simply, the amplifier will support most of the smartphones, PCs, CD/DVD players and so on.

Customers note that the amplifier is fairly easy to set up, and the sound is deep and rich, but the price remains a major drawback.

As the brand name suggests, this Chinese amplifier can be a ‘good old buddy’ for audiophiles and audio enthusiasts, thanks to the high level of customization offered by the manufacturer.

For example, when choosing the preferred model on AliExpress, you can request an amplifier that supports Bluetooth wireless connection. While a bit more expensive compared to the default configuration, it will give you more flexibility in terms of sound transmission from your Bluetooth-supported devices.

According to the manufacturer, the working voltage of this model is more than 300 V, which is 10-20 times more powerful than ordinary transistor amplifiers.

Depending on the configuration, the amplifier will be equipped with 4 or 5 tubes, which perform incredibly well with full-range speaker vocals and strings.

As for customer reviews, they are mostly positive, except for a couple of recommendations to replace the default tubes with better ones.

It uses two 6K4 tubes, which render the vocals in a dense fashion, allowing you to fully enjoy the high-fidelity sound.

Whether you enjoy listening to symphonies or Hi-Fi music, this CHi-Fi amplifier with improved compatibility can vastly improve sound quality.

It uses two sets of tubes: two 6F1 and two 6U1 model tubes, which deliver rich and clean sound.

It is a 6P1 Chinese tube DIY kit, characterized by powerful sound with deep bass. It features a VU meter, headphones output, as well as volume, bass and treble regulators. As the manufacturer states, the output power of this amplifier is about 4W, while a speaker has a sensitivity above 90dB.

The tech components are encased in a 15 cm case with wooden panels, meaning that the device is fairly small and will fit well on your table.

There are no major complaints by customers, although some claim that the tubes may have traces of use upon delivery, which doesn’t reflect well on the seller.

The amplifier has multiple audio inputs (both physical and digital), ensuring that most devices can be connected: you’ll get Bluetooth 5.0, USB, COAX, and others.

While complimenting the sound quality, some customers complain that the tubes were damaged upon delivery, but this could be blamed on poor handling at the post office.
