No other headphone amp offers as much power with so few components in the signal path as the Soloist. Conventional headphone amplifier designs use IC op-amps in the signal path. Since each op-amp contains over 50 low-quality components, most of them not even required for audio playback, these packed-together chips distort the audio signal, it’s in their nature. The Soloist is perfectly tailored with a symmetrical current feedback circuit with only 21 components in the signal path explaining the wonderful sound.
