The term 'High Fidelity' means 'faithful reproduction' i.e. without adding or subtracting anything at all from the musical signal. This implies that in order to achieve a clean, clear transparent sound quality, there has to be zero added distortions of any nature (including THD, IMD, added noise, or slew rate limiting).
With the Ultra Analog THE 1, THD+N and IMD are virtually immeasurable, making it the highest performing Operational Amplifier available today.
Simply, the best kept secret in the Professional Audio Industry - Ultra low noise, Ultra low distortion (0.00001% THD+N), and high slew rate...
