TOPPING L30 Headphone Amplifier / Preamplifier NFCA Black

Ultra high performance NFCA modules

The L30 uses the same NFCA (Nested Feedback Composite Amplifier) modules as the Topping A90 flagship. The hybrid voltage/current feedback architecture combined with UHGF (Ultra High Gain Feedback) technology provides excellent AC and DC performance. The unit's high output level allows it to easily accompany low impedance headphones. The L30's ultra-low noise of 0.3µV gives it a considerable lead over the competition, as does its extremely high dynamic range of 141dB. It is therefore capable of delivering vivid sound reproduction with unrivalled clarity. During measurements, the high limits of the Audio Precision APX555B analyzer have even been reached!

Suitable for all types of headphones

With an output level of 26Vp-p, a power of 2x 3500mW and an output impedance of less than 0.1ohm, the L30 will have no problem fitting to all types of headphones. The L30 will work equally well with high impedance headphones that require a high power input, as well as with in-ear earphones with very high sensitivity.

Excellent
Service audiophonics impeccable comme d'habitude.

Ampli parfaitement neutre et transparent.
Très grande précision alliée à une grande douceur.
Le sélecteur de gain est indispensable je trouve , j'avais systématiquement sur mes autres amplis un problème pour régler le volume avec mon Sennheiser Momentum ( trop de gain).
Tout cela pour un prix mini.
