Every speaker builder now the moment when you have an idea for your own customized speaker and you are searching for an amplifier which fits the needs. Most of the chinese Amplifiers has a horrible background noise or large transient noise. Nothing is worser than to see your own build speaker which is ruined through a bad amplifier.
