L30 uses the same NFCA (Nested Feedback Composite Amplifier)module from flagship A90.Voltage Current hybrid feedback architec-ture 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 range of 141dB and no audible noise and darkest background for the most sensitive IEMs.
Upper limit of performance was limited by APX555B
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 0.1Ohm.It easily drives power-hungry headphones with a wide range of different impedance.
3 step gain settings,adapt to various sensitivities
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.
