Redo, an amplifier isn't a musical instrument. All that it does to make the music "come to life" is to increase the input voltage about 25-30 times so that it's loud enough to hear. All amplifiers do this. One which would make the sound different, rather than amplifying transparently, would either be incompetently designed or damaged. A basic principle of audio technology, well-summarized by the Audio Critic, is that "Electronic Signal Paths Do Not Have a Personality!".

Enjoy the music, not the equipment.
