HIgh-performance Headphone amplifier
with some some serious punch!Topping’s L30 Headphone Amplifier is the companion to the highly regarded E30 DAC. With the ability to be utilised as either an amplifier or indeed a pre-amplifier, the L30 comes fully equipped with NFCA modules as found in Topping’s flagship A90, features 3-step gain settings and is fully Hi-Res Audio certified.
The L30 uses NFCA (Nested Feedback Composite Amplifier) which enable it to drive low impedance headphones with the upmost of ease. The L30 also boasts an ultra-low noise level of 0.3uV that blows away similarly priced competitors, while producing a high dynamic range of 141dB with no audible noise or dark backgrounds in sensitive IEMs!
