TOPPING L30 II

TOPPING L30 II - L30 II

TOPPING L30 II NFCA Big Power Low Noise 3 Gain HIFI Desktop Headphone Amplifier for E30 DAC

Description

Headphone amp/ preamp application

Hi-Res Audio

3 gain settings, high, mid, low

NFCA modules

<0.00006% THD+N

144dB DNR

<0.3ɥVrms noise

<0.1Ω output impedance

3500mW x 2 @16Ω, 260mW x 2 @300Ω, maximum output power

*The actual noise level is obtained by boosting the noise of L30II by 100 times using a low noise amplifier in front of the APX555B then dividing the measured noise by 100 times.

What are the differences from L30?

L30 II

Amp: improved NFCA

THD+N: 0.00006%

Dynamic range: 144dB

Output power at 300Ω load: 560mW x 2

Gain: -14dB/0dB/16.5dB

Output voltage: 37Vpp

L30

Amp: NFCA

THD+N: 0.00007%

Dynamic range: 141dB

Output power at 300Ω load: 280mW x 2

Gain: -9.9dB/0dB/9.5dB

Output voltage: 26Vpp

Improved NFCA

L30 II uses redesigned NFCA(Nested Feedback Composite Amplifier)module. It provides 2x output power at 300Ω load to L30.

The new circuit has 0.3ɥV ultra-low noise and 144dB dynamic range as well as 0.00006% tHD+N.

*3500mW x 2 @16Ω

*2700mW x 2 @32Ω

*2000mW x 2 @64Ω

*260mW x 2 @300Ω

Sound quality is never a problem

With the help of NFCA, L30 II easily reaches the top of the industry, and it has almost perfect performance regardless of distortion, dynamic range, and multi-tone esting.

Compatible with almost all kinds of headphones

L30 II output has high output voltage, high current, low output impedance, so no headphones that can’t be dealt with.

High output voltage can easily drive high impedance headphones; high output current allows low-sensitivity headphones to obtain enough power.

The low output impedance will not bring unnecessary effect on FR when driving low-impedance headphones.

Different headphones can be easily driven by the L30 II.

*Output voltage: 37Vpp

*Output peak current: 1400mA

*Output impedance: <0.1Ω

Low distortion while outputting high power

The L30II can maintain ultra-low distortion output under high power load. Under 32Ω load and 2500mW output, the THD+N is lower than 0.00008%; under 300Ω load and 300mW output, the THD+N is lower than 0.00007%.

The gain settings to suit different needs

L30 II has three gain options: -14dB, 0dB, 16.5dB. Improved gain settings can cover a wider range of needs to meet the needs of different headphones from low-sensitivity full-sized over-ears to high-sensitivity IEMs. With the help of extremely low noise 0.3ɥV, even IEMs will not hear any background noise.

E30 II is the best DAC for L30 II

Best combo for active speakers

We also recommend that L 30 II and E30 II be used with active speakers. Connect the two outputs of L30 II to headphones and active speakers. By switching the outputs of L30 II, you can enjoy music on headphones and active speakers respectively.
