Do I need to add a preamp to the integrated amplifier? Many audiophiles have this question. There are three factors here. First, is the signal output from the audio source large? The output signal of many foreign CD players is relatively small. Adding a preamp can amplify the signal. The second is the sensitivity of the speaker. For speakers with a sensitivity below 90dB, the sound performance will be better if a preamp is added. The third is the amplification of the amplifier. A standard integrated amplifier with a gain of 30dB can amplify the input signal by about 15 times. The integrated amplifier with a gain of 20dB has an amplification of about 10 times, which is slightly insufficient and lacks dynamics. If you have very high requirements for sound, it is best to add a preamplifier as a supporting device and use the integrated power amplifier as a power amplifier. The preamplifier can increase the amplification amount by 10 times, and the combined gain of the two units can reach 40dB. At this time, the power amplifier will push more easily, the sound density will be high, the details will be rich, and the transient will be stronger, and the performance of the sound system will be perfect.
Stereo amplifier knowledge is as follows:\n\n1. A stereo amplifier is an audio device that can amplify weak electrical signals and modify and render the sound at the same time. It allows you to hear clearer, more realistic and more detailed sounds. \n2. A s
For home theater, the decisive factor in home theater must be the subwoofer. It can be said that the subwoofer is the soul of the entire home theater. Why do you need a subwoofer?1. In audio, the low-frequency part consumes the most power when reproducing it, especially the low-frequency part below
Simply share some knowledge about tube amplifiersTube amplifiers operate at high voltage and low current. The screen voltage of the final power amplifier tube can reach 400-500V or even thousands of volts, while the current flowing through the tube is only tens to hundreds of
Three Factors Affecting the Gallbladder SystemDoes the integrated tube amplifier need to add a preamplifier? Many enthusiasts have such questions. There are three factors here.

Do you also like to listen to vacuum tube speakers? The pleasant sound it produces comes from the vacuum tube circuit, and many factors are taken into consideration to achieve such a pleasant sound quality. The author will share with us his experience in self-study of vacuum tube circuit technology,
Why tube amplifiers don’t deserve to be called “hi-fi” audio equipment?What should I do if the final sound of the amplifier is unpleasant?Use tubes for the preamp!Once a power amplifier uses vacuum tubes, it basically falls out of the category of "highly faithful audio"!Don't jump, grab the ground w
The basic composition of the listening system and the selection of amplifiers and speakersFirst, let’s talk about the composition of a complete system. Simply put, it can basically consist of the following three parts:Audio source, amplifier, speakers.Sound source:Regardless of digital or analog sig
How powerful should the audio amplifier be?In a sound system, using a power amplifier properly is not as simple as you think. It is really necessary to discuss it.1. What power amplifier should be used? Generally, before choosing a power amplifier, the first problem you e
