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.
