Ultra High-Performance NFCA Modules

The TOPPING L30 headphone amplifier incorporates NFCA(Nested Feedback Composite Amplifier) modules from the flagship A90. The TOPPING L30 amplifier provides excellent AC and DC performance by using a voltage-current hybrid feedback architecture.

The L30 amplifier incorporates TOPPING’s UHGF (ultra high gain feedback) technology in a voltage-current hybrid feedback architecture. The TOPPING L30 amplifier can drive any pair of headphones without compromises, providing a perfect and flawless musical representation accompanied by unparalleled levels of clarity.

Surpassing The Limits Of APX555B

The APX555B is a two-channel audio analyzer by Audio Precision© (AP). It is widely recognized as the global standard in audio testing equipment, helping engineers worldwide design, validate, characterize, and manufacture audio products.  Over the years, we have witnessed many companies claiming ridiculous numbers with no proof to back up their claims. High output power, low distortion, and high dynamic range.

Three Gain Settings

TOPPING L30 has multiple gain settings including -9.9dB gain setting to allow for the finest, granular gain control.

TOPPING L30 Gain Settings:

• Low (-9.9dB).
• Mid (0dB).
• High (9.5dB).

Three gain settings that include unity and low-gain (-9.9dB) should provide a considerable amount of usable volume control for sensitive IEMs. Switching between the three gain levels is a relatively straightforward process, simply flick the dedicated metal gain toggle switch on the front panel.

Low and mid-gain levels (-9.9dB and 0dB) are suitable for driving efficient over-ears and IEMs, Owners of power demanding, hard-to-drive headphones will find themselves frequently switching to high gain (9.5dB). TOPPING L30 is capable of powering all different kinds of headphones, from highly sensitive IEMs to power demanding full-size headphones.

Excellent Amplifier + Preamp

The TOPPING L30 can be used in two modes, amplifier and preamplifier modes. One of the advantages of TOPPING’s NFCA modules is their ability to transfer the same performance and allow their use as a state of the art preamplifier. The NFCA modules of the L30 are capable of providing the same transparent performance of the L30, but doing so with an astonishingly low out impedance of 20 ohms.

The preamp functionality is easily accessible by a dedicated switch on the front panel. Many users will appreciate this approach as it avoids the need to unplug your headphones to use the preamp function. To use the TOPPING L30 as a preamplifier, simply toggle the front switch, and now you can use the L30 to control the volume of your powered speakers or attenuate the volume of your power amplifier.

External AC Power Supply

To preserve the tiny footprint and ensure consistent performance under all circumstances, TOPPING chose to take a different approach using an external AC adapter to power the L30.

Using an external transformer-based AC adapter to convert a higher-voltage current provides many advantages compared to DC.
