Specs

THD+N at 1kHz A-weighted: <0.00007% @ 500mW output (32Ω) and <0.00006% @ 80mW output (300Ω). This 7uVrms measurement reflects the level of distortion and noise present in the output signal at a frequency of 1kHz.

At an impedance of 32Ω and an output of 500mW, the Total Harmonic Distortion plus Noise (THD+N) at 20-20kHz is less than 0.0001%. For an impedance of 300Ω and an output of 80mW, the THD+N is even lower, at less than 0.00009%. These results showcase exceptional sound quality with minimal distortion levels.

Output at 1kHz with A-weighting reaches a maximum of 141dB, showcasing the impressive dynamic range at the same frequency. The frequency response spans from 20Hz to 40kHz with a minimal deviation of ±0.05dB.

Huge Purposes for Headphones. L30 has a excessive voltage swing of 26Vp-p, energy of 3500mW per channel when each channels are pushed and output impedance of lower than 0.1ohm. It simply drives energy for headphones with a variety of various impedance.
3 Steps Achieve Settings. L30 is supplied with three acquire settings of -9.9dB/0dB/9.5dB.Wide selection of acquire settings and the 0.3uVrms ultra-low noise makes L30 simply adapt to all forms of headphones from extraordinarily delicate IEMs to most energy demanding full-sized over-ears
Excessive High quality Amplifier. The NFCA modules of L30 should not solely capable of drive the headphones but additionally apply to be a pre-amplifier with the identical ultra-high efficiency. When it’s in preamp mode, the output impedance is as little as 20 ohm, which is extensively appropriate for numerous units. It’s a nice companion of lively screens stacked with E30 DAC when L30 working in preamp mode
Good Companion for Audiophile. Designed with a conveyable and compact physique, L30 might be your HiFi gadget on-the-go for day by day life. Merely take it anytime anyplace, you’ll get pleasure from pure excessive constancy music
