Feature(may vary by option.)
●👍 Ultra-High Performance NFCA modules ▶️ L70 uses the same NFCA (Nested Feedback Composite Amplifier) module with A90. Voltage current hybrid feedback architecture along with UHGF (UItra High Gain Feedback) technology provide excellent DC and AC performance, ultra-low THD+N and absurdly high dynamic range of 146dB.
●👍 Fully balanced ▶️ The L70 is compatible with common headphone jacks including: 4-pin XLR balanced, 4.4mm balanced, 6.35mm single-ended, and 3.5mm single-ended. The built-in fully balanced amplifier circuit can not only fit well with balanced headphones, but also have perfect performance with single-ended headphones.
●👍 Compatible with almost all kinds of headphones ▶️ TOPPING designed the L70 to be able to power the vast majority of headphones. With high output voltage, it easily drives high impedance headphones. With high output current, it easily drives low impedance headphones. And with low output noise, it easily powers highly sensitive IEMs without creating background hiss.
●👍 A Headphone Amp, also a Preamp ▶️ The L70 is not only able to drive the headphones but also served as a preamp. When it is in preamp mode, you can get the same high performance as the headphone amp mode, and the 20ohm SE and 40ohm balanced output impedance are widely suitable for various power amplifiers. The full-featured remote control makes it more convenient for you to use.
●👍 E70 will be the best dac for L70 ▶️ L70 and E70 have fully matched design languages and styles, L70 is suitable for almost all kinds of headphones. The E70 and L70 can be switched on and off through the 12V Trigger interface, so that the L70 can be synchronized with the automatic or manual on/off of the E70.

Ultra-High Performance NFCA Module
Adopts the same NFCA module with A90, it provides a high performance to driving kinds of headphones.
-
Low distortion while outputting high power
The L70 can maintain ultra-low distortion output under high power load.
-
Multiple Input Ports
L70 provides Combo and RCA input port, and is available for XLR, TRS and RCA connection.
-
Customize Settings
A safe volume can be set for the L70 to avoid sudden loud sound after power on/input switch
-
A Headphone Amp, also a Preamp
In preamp mode, you can get the 20ohm SE and 40ohm BAL output impedance to meet various power amp.
GND Ground Loop Noise Terminator
Ground loop noise may be encountered when multiple devices are used in combination. L70 has a GND/LIFT switch to solve this problem. When in normal use, set it to GND; and when ground loop noise is encountered, switch it to LIFT. Then the ground loop noise is terminated.
12V Trigger Interface
The L70 is equipped with a 12V Trigger in & out interface. With only one easy-to-obtain 3.5mm to 3.5mm cable, the L70 can be turned on and off synchronously with other devices equipped with a 12V Trigger interface.
L70 can easily drive different headphones.

Various Headphone port
L70 is compatible with common headphone jacks including: 4-pin XLR balanced, 4.4mm balanced, 6.35mm single-ended, and 3.5mm single-ended.
-
8 Output Settings
L70 can be adapted more personalized when connecting different earphones and other devices, wich greatly improves the convenience of use.

High-performance headphone amp
- Output Voltage: Balanced 52Vpp / SE 26Vpp
- Output Current: Peak 1.4A
- Output Impedance: <0.1Ω
- High output voltage can easily drive high impedance headphones
- High output current provides enough power for low-sensitivity headphones
- Low noise allows high-sensitivity IEMs unaffected by any background noise
- Low output impedance wont unduly affect FR when driving low-impedance headphones
