Technical specifications like frequency response and distortion ratings provide valuable insights into an amplifier's performance and sonic characteristics. Frequency response indicates the range of frequencies the amplifier can reproduce accurately, with wider frequency response typically indicating better audio fidelity. Distortion ratings, such as Total Harmonic Distortion (THD), quantify the level of signal distortion introduced by the amplifier, with lower values indicating cleaner audio output. Consider these specifications alongside real-world listening tests and reviews to assess an amplifier's sonic performance accurately.
