A “small hot hatch” like HPA
Topping L30 Headphone amplifier
- Hi-Res Audio
- 3 step Gain settings
- NFC A Modules
- <0.00007% THD+N
- 141dB DNR
- <0.3uVrms Noise
- <0.1Ω Output Impedance
- 3500mWx2 Maximum output power
The actual noise level is obtained by boosting the noise of L30 by 100 times using a low noise amplifier in front of the APX555B then dividing the measured noise by 100 times.
Ultra-High Performance NFCA modules
L30 uses the same NFCA (Nested Feedback Composite Amplifier) module from flagship A90. Voltage Current hybrid feedback architecture along with UHGF (Ultra High Gain Feedback) technology provides excellent DC and AC performance.
High output current drive capability allows the amp driving low impedance headphones with ease. Ultra-low noise of 0.3uV is miles ahead of the competition, giving an absurdly high dynamic r^nge of 141 dB and no audible noise and darkest background for the most sensitive IEMs.
Wide range of adaptation to headphones
L30 has a high voltage swing of 26Vp-p, power of 3500mW per channel when both channels are driven and output impedance of less than O.1 Ohm. It easily drives power-hungry headphones with a wide range of different impedance.
3 step gain settings, adapt to various sensitivities
L30 is equipped with three gain settings of -9.9dB/0dB/9.5dB. Wide range of gain settings and the 0.3uVrms ultra-low noise makes L30 easily adapt to all types of headphones from extremely sensitive lEMs to most power demanding full-sized over-ears.
Also an excellent preamp
The NFCA modules of L30 are not only able to drive the headphones but also apply to be a preamplifier with the same ultra-high performance. When it is in preamp mode, output impedance is as low as 20ohm, which is widely suitable for various devices.
L30+E30, what a wonderful combination
It’s a great companion of active monitors stacked with E30 DAC when L30 working in preamp mode.
