IWISTAO Vacuum Tube 6922/E88CC Tubes Preamplifier Stage Built-in Regenerative Power HIFI Audio

Many electrical appliances are converted from AC power to DC. Work at the peak of the AC, which causes the peak of the AC to be cut, causing a lot of harmonic interference. The distortion is generally up to 5%, or even higher when it become more serious. Power processing equipment can effectively reduce Interference, but it can’t be eliminated. The P20 which is recognized as the best American regenerative power supply, has an index of only 0.5%, and the sound is much better!

However, if the power of the regenerative power supply is large, the distortion is difficult to be low. If there is only power that less than 100W ten, it can still achieve ultra-low distortion power, which is applied to the pre-amplifier.

Now, many audiophiles had used a regenerative power equipment, which brings amazing changes in sound, reduces power interference, and significantly improves sound quality.

This tube preamplifier stage built-in an ultra-low distortion 60W regenerative power supply in order to achieve ultra-low distortion and ultra-high signal-to-noise ratio, its distortion is less than 0.01%, ultra-low distortion.

As you know, the greater the material density of the speaker enclosure, the less the vibration produced by the enclosure. Solid wood is more reflective of sound than other materials, and tightness of the wood is higher, and the sound can be effectively expressed by the vibration of the air inside the box. We often say that the sound of wooden speakers is warm, in fact, the word warm means the balance of tri-band that are low, medium and high frequency; if the frequency is too low or too high, it will make people feel uncomfortable. The advantage of wooden speaker is that its playback effect is good, the vibration of the sound inside the box is stable, and the sound effect will be balanced and full.
