🏠 For Audiophiles at Home
I’ve always loved the ritual of coming home, settling into my favourite chair, and firing up a dedicated setup. Gear labelled For Audiophiles at Home is made for those moments — when you can really sit back and appreciate music in its purest form 🛋️. These products tend to be more powerful, larger, and often require wall power — perfect for a stationary rig.
Here’s the trade-off: these setups often involve external DACs, amps, or full-size headphones, which means more space, more power, but also more immersive listening. They shine when used in quiet environments, where detail, depth, and dynamics can truly be appreciated.
When you see '🏠 For Audiophiles at Home' products, expect: exceptional fidelity, stronger output, and the kind of soundstage that makes you never want to leave your listening chair.
🔗 Connect With Cable
In my experience, there’s still nothing like the dependability of a wired connection when it comes to audio 🎧. I love describing it as the direct flight of music — no delays, no turbulence. When a product says “Connect with Cable,” it means you’re getting the most reliable signal path, with zero wireless compression and minimal interference.
Here’s what’s actually happening: a physical cable transmits uncompressed analog or digital signals directly from your source to your gear. This results in lower latency, no signal drops, and consistently better sound — especially when paired with a good DAC or amp. It’s ideal for critical listening, gaming, and professional use. The trade-off? You’re tethered — but for a lot of audiophiles, that’s a small price to pay for sonic purity.
When you see '🔗 Connect With Cable' products, expect: pure, uninterrupted sound quality that lets your gear perform at its full potential — perfect for focused, high-fidelity listening.
Why it Sounds Amazing
🚀 Power Output
I like to think of power output in audio gear like engine horsepower, it determines how much muscle your setup really has 💪. Whether you’re trying to drive a pair of power-hungry planar headphones or just want headroom for dynamic peaks, power output is the spec you want to check first.
Technically, it refers to the amount of electrical power (measured in mW or Watts) an amp or DAC/Amp combo can deliver to your headphones. More power means better control, improved dynamics, and the ability to handle demanding gear without distortion. But more isn’t always better, too much power with sensitive IEMs can introduce hiss or harshness.
When you see '🚀 Power Output' products, expect: strong driving capability, better dynamics, and optimal performance with headphones that need serious juice to shine.
⚖️ Balanced Output
I often say balanced output is like using both hands to carry something heavy — it distributes power evenly and keeps things stable. In audio gear, balanced output helps reduce unwanted noise and interference, especially over longer cables. Think of it as a cleaner, more efficient way to transmit your music, ideal for anyone using high-end DACs, amps, or studio-grade headphones 🎧. You’ll typically find it on gear with XLR or 4.4mm connectors, and it's a must-have if you’re chasing that ultra-clean signal path.
Here’s what’s actually happening: a balanced output uses two separate signals, one inverted, so when interference is picked up along the cable, it gets cancelled out when the signals are recombined. The result? Cleaner audio, better dynamic range, and more power output — especially when paired with balanced headphones. The trade-off? You’ll need gear that supports balanced connections on both ends to really enjoy the benefits.
When you see '⚖️ Balanced Output' products, expect: ultra-low noise, more headroom, and better synergy with high-impedance headphones or sensitive IEMs — ideal for serious listening setups.

DESCRIPTION
TOPPING INTRODUCES A HIGH-PERFORMANCE AMPLIFIER - THE L70, A PERFECT MATCH FOR THE E70
One of the first manufacturers of some of the cleanest and distortion-free DACs & Amps is TOPPING. Their product lineup has received positive reviews and is well-liked by the audiophile community. TOPPING amps have incredible performance capabilities and are powerful, clean, and precise. To level up their game, TOPPING engineers had to come up with something unique, which gave rise to the ultra-high-performance headphone amplifier - the L70. TOPPING engineers have incorporated their most dependable and high-performing NFCA module in the L70. It has been "calibrated" to be a perfect match; with the high-performance DAC - the E70. The L70 is an all-around headphone amplifier that can be "paired" with your preferred choice of DACs. Experience the might and power of the L70 that can power even the most demanding headphones of the lot.
EXPERIENCE THE MAGIC OF NFCA MODULE FUSED WITH UHGF PROVIDING SPECTACULAR AMPLIFICATION
TOPPING is known to incorporate high-grade components, and the L70 is no different. It hosts the same ultra-high performance NFCA (Nested Feedback Composite Amplifier) module as the A90. TOPPING has introduced voltage current hybrid feedback architecture fused with UHGF (Ultra High Gain Feedback) technology to provide excellent DC and AC performance, ultra-low THD+N and a high dynamic range of 146dB. Ahead of the competition, the high output current drive capabilities, low output impedance, and ultra-low noise of 0.3uV provide more than enough assurance for driving headphones. With a variety of features, enabling high-fidelity music to be vividly rendered on various headphones. Experience the magic of L70 and enjoy your music; in a way, you have never experienced before.
DOUBLES-UP AS A PREAMPLIFIER FUSED WITH A 12V TRIGGER INTERFACE
In addition to the amp mode with exceptional output levels, the L70 also has a preamplifier mode. When it is in preamp mode, you can get the same high performance as the headphone amp mode, and the 20-Ohm SE and 40-Ohm balanced output impedance are widely suitable for various power amplifiers and speakers. The full-featured remote control makes it more convenient for you to control the L70 from the comfort of your couch. This design provides greater convenience when connected to a power amplifier or monitor speakers. The TOPPING L70 also hosts a 12V Trigger interface. The 12V Trigger interface on the L70 can be "configured" for active control (Trigger out) or passive control (Trigger in). 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. With this setup, you can connect L70 to the TOPPING E70 high-performance DAC, and you can form your desktop audio chain.
SUITABLE FOR VARIOUS HEADPHONES WITH IMPECCABLE POWER DELIVERY WITH TWO GAIN LEVELS
The engineers at TOPPING have calibrated the L70 to be compatible with almost all kinds of headphones. L70's output has high output voltage, high output current, low noise, and low output impedance, allowing it to power most headphones. The high output voltage can drive high-impedance headphones, and low-sensitivity headphones can obtain sufficient power thanks to the high output current. High-sensitivity IEMs are not affected by background noise thanks to the low noise of the L70. When driving low-impedance headphones, the low output impedance won't have an unneeded impact on the frequency response (FR). The L70 is capable of simply "driving" a variety of headphones. To provide even more control over the choice of your headphones/IEMs, the L70 has a two-level gain setting. The two gain settings cover a range of needs to meet the requirements of different headphones, from low-sensitivity full-sized over-ears to high-sensitivity IEMs. With the help of low noise 0.3uV, even IEMs will not capture any background noise.
GROUND LOOP NOISE TERMINATOR WITH R2R VOLUME CONTROL DELIVERS A FLAWLESS LISTENING EXPERIENCE
Ground loop noise is "experienced" when multiple devices are "connected" in combination. The 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," which terminates the ground loop noise. The L70 has a customised volume control that uses an R2R volume control composed of relays and resistor networks, bringing the advantages of precise control, longevity, complete channel balanced and remote control. The L70 can be "set" to memorise the volume and gain for "8" output settings. It can be adapted to be more personalised when connecting different earphones and other devices, which improves the convenience of use. To prevent unexpected loud noises after pressing the power on/input switch, the L70 can have a safe volume adjusted according to the customised settings.
BUNDLED WITH REMOTE CONTROL AND THOUGHTFUL INPUTS AND OUTPUTS FOR EASY CONNECTIVITY
The L70 comes with a fully functional remote, which allows you to; access various functions with "ease". The L70 is compatible with "common" headphone jacks like 4-pin XLR balanced, 4.4mm balanced, 6.35mm single-ended, and 3.5mm single-ended. The built-in fully balanced amplifier circuit fits well with balanced headphones and has "perfect" performance with single-ended headphones. The L70 provides combo and RCA input ports and is available for XLR, TRS and RCA connection. With these functionalities, the TOPPING L70 is the most versatile amplifier; that will make your music come alive!

TOPPING INTRODUCES A HIGH-PERFORMANCE AMPLIFIER - THE L70, A PERFECT MATCH FOR THE E70
One of the first manufacturers of some of the cleanest and distortion-free DACs & Amps is TOPPING. Their product lineup has received positive reviews and is well-liked by the audiophile community. TOPPING amps have incredible performance capabilities and are powerful, clean, and precise. To level up their game, TOPPING engineers had to come up with something unique, which gave rise to the ultra-high-performance headphone amplifier - the L70. TOPPING engineers have incorporated their most dependable and high-performing NFCA module in the L70. It has been "calibrated" to be a perfect match; with the high-performance DAC - the E70. The L70 is an all-around headphone amplifier that can be "paired" with your preferred choice of DACs. Experience the might and power of the L70 that can power even the most demanding headphones of the lot.
EXPERIENCE THE MAGIC OF NFCA MODULE FUSED WITH UHGF PROVIDING SPECTACULAR AMPLIFICATION
TOPPING is known to incorporate high-grade components, and the L70 is no different. It hosts the same ultra-high performance NFCA (Nested Feedback Composite Amplifier) module as the A90. TOPPING has introduced voltage current hybrid feedback architecture fused with UHGF (Ultra High Gain Feedback) technology to provide excellent DC and AC performance, ultra-low THD+N and a high dynamic range of 146dB. Ahead of the competition, the high output current drive capabilities, low output impedance, and ultra-low noise of 0.3uV provide more than enough assurance for driving headphones. With a variety of features, enabling high-fidelity music to be vividly rendered on various headphones. Experience the magic of L70 and enjoy your music; in a way, you have never experienced before.
DOUBLES-UP AS A PREAMPLIFIER FUSED WITH A 12V TRIGGER INTERFACE
In addition to the amp mode with exceptional output levels, the L70 also has a preamplifier mode. When it is in preamp mode, you can get the same high performance as the headphone amp mode, and the 20-Ohm SE and 40-Ohm balanced output impedance are widely suitable for various power amplifiers and speakers. The full-featured remote control makes it more convenient for you to control the L70 from the comfort of your couch. This design provides greater convenience when connected to a power amplifier or monitor speakers. The TOPPING L70 also hosts a 12V Trigger interface. The 12V Trigger interface on the L70 can be "configured" for active control (Trigger out) or passive control (Trigger in). 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. With this setup, you can connect L70 to the TOPPING E70 high-performance DAC, and you can form your desktop audio chain.
SUITABLE FOR VARIOUS HEADPHONES WITH IMPECCABLE POWER DELIVERY WITH TWO GAIN LEVELS
The engineers at TOPPING have calibrated the L70 to be compatible with almost all kinds of headphones. L70's output has high output voltage, high output current, low noise, and low output impedance, allowing it to power most headphones. The high output voltage can drive high-impedance headphones, and low-sensitivity headphones can obtain sufficient power thanks to the high output current. High-sensitivity IEMs are not affected by background noise thanks to the low noise of the L70. When driving low-impedance headphones, the low output impedance won't have an unneeded impact on the frequency response (FR). The L70 is capable of simply "driving" a variety of headphones. To provide even more control over the choice of your headphones/IEMs, the L70 has a two-level gain setting. The two gain settings cover a range of needs to meet the requirements of different headphones, from low-sensitivity full-sized over-ears to high-sensitivity IEMs. With the help of low noise 0.3uV, even IEMs will not capture any background noise.
GROUND LOOP NOISE TERMINATOR WITH R2R VOLUME CONTROL DELIVERS A FLAWLESS LISTENING EXPERIENCE
Ground loop noise is "experienced" when multiple devices are "connected" in combination. The 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," which terminates the ground loop noise. The L70 has a customised volume control that uses an R2R volume control composed of relays and resistor networks, bringing the advantages of precise control, longevity, complete channel balanced and remote control. The L70 can be "set" to memorise the volume and gain for "8" output settings. It can be adapted to be more personalised when connecting different earphones and other devices, which improves the convenience of use. To prevent unexpected loud noises after pressing the power on/input switch, the L70 can have a safe volume adjusted according to the customised settings.
BUNDLED WITH REMOTE CONTROL AND THOUGHTFUL INPUTS AND OUTPUTS FOR EASY CONNECTIVITY
The L70 comes with a fully functional remote, which allows you to; access various functions with "ease". The L70 is compatible with "common" headphone jacks like 4-pin XLR balanced, 4.4mm balanced, 6.35mm single-ended, and 3.5mm single-ended. The built-in fully balanced amplifier circuit fits well with balanced headphones and has "perfect" performance with single-ended headphones. The L70 provides combo and RCA input ports and is available for XLR, TRS and RCA connection. With these functionalities, the TOPPING L70 is the most versatile amplifier; that will make your music come alive!
