Fully Balanced NFCA Headphone Amplifier
Topping - L70
(Black)
Ultra-High Performance NFCA modulesTopping's L70 uses the same NFCA (Nested Feedback Composite Amplifier) module as the A90, giving it that TOPPING “house sound”. This, along with UHGF (Ultra High Gain Feedback) technology, provides excellent DC and AC performance, ultra-low THD+N, and an absurdly high dynamic range of 146dB.
Fully balancedThe built-in fully balanced amplifier circuit performs exceptionally well with both balanced and single-ended headphones. Additionally, the L70 includes four jacks to accommodate most headphones: 4-pin XLR balanced, 4.4mm balanced, 6.35mm single-ended, and 3.5mm single-ended.
Ultimate compatibilityTopping 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.

Amazing Features
Say goodbye to ground loop noise
When multiple pieces of equipment are used in conjunction, ground loop noise can occur. Ground loop noise most often manifests as a buzzing or humming sound, which is capable of being loud enough to damage speakers. Although it's known to happen most often in single-ended feeds, it can happen in balanced feeds, too.
The L70 solves this issue with a GND/LIFT switch. When in normal use, set the switch to GND. If you encounter ground loop noise, set the switch to LIFT, which will change the ground point of the L70 from its chassis to the equipment it’s connected to, eliminating the noise.
2 gain settingsThe L70 has 2 gain settings, which cover a wide range of use cases from low-sensitivity full-sized headphones to high-sensitivity IEMs.
R2R volume controlThe L70 uses an R2R volume control composed of relays and resistor networks, bringing the advantages of precise control, longevity, and complete channel balance.
Doubles as a pre-amp With the L70 in pre-amp mode, connect a power amplifier to drive bookshelf, desktop, or floor speakers. With the included remote control, you can control it all from the comfort of your couch.
Volume memorizationThe L70 can memorize the volume and gain settings for 8 separate outputs. These settings can be customized to different headphones and other devices, vastly increasing its usability.
12V trigger interface The L70 comes with a 12V trigger on the back panel. This simple jack lets you create a network between any units that also feature a 12V trigger. When connected, it makes one product control the power of the other products in the system. When you turn on one unit, the rest of the system comes on automatically.
