Topping is the GOAT for the price! - Amazing amp! Reference-Grade Control, Effortless Power, and Dead-Silent Performance. Remote control, Volume know has a very satisfying click for each db change.

Next step The E70 Velvet! ## Features - 👍 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BKG65KXJ | | Best Sellers Rank | #77,712 in Electronics ( See Top 100 in Electronics ) #51 in Audio Component Preamplifiers | | Customer Reviews | 4.3 4.3 out of 5 stars (40) | | Date First Available | October 25, 2022 | | Item Weight | 3.58 pounds | | Item model number | TOPPING-L70-BLACK-KGUSS | | Manufacturer | TOPPING | | Package Dimensions | 12.87 x 10.75 x 4.09 inches | ## Images ![Topping L70 Fully Balanced NFCA Headphone Amp - 4-Pin-XLR/4.4mm Balanced/6.35mm SE Headphone Jacks Amplifier 7500mW x 2 Ouput R2R Volume Control HiFi Amp Audio Hi-Res Preamplifier(Black) - Image 1](https://m.media-amazon.com/images/I/51T5+HT5gWL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ More power than needed *by C***R on March 12, 2026* More power than you'll ever need, and clean that is also ### ⭐⭐⭐⭐⭐ Amazing amp!

Next step The E70 Velvet! ### ⭐⭐⭐ Not adequate for my setup with two flaws *by J***P on July 24, 2025* I thought this amp would have enough power for my Audeze LCD-S20. I was wrong. I then encountered a known flaw with Topping amps that affects planar headphones with low impedance and high sensitivity. The amp will go into safe mode and cut out audio when the volume is turned up beyond the 70 range. Topping tried to address this with a firmware update but this didn’t fix the problem. I returned the L70 and tried the A70 Pro and ran into the same problem. No issues with dynamic headp. ## Frequently Bought Together - Topping L70 Fully Balanced NFCA Headphone Amp - 4-Pin-XLR/4.4mm Balanced/6.35mm SE Headphone Jacks Amplifier 7500mW x 2 Ouput R2R Volume Control HiFi Amp Audio Hi-Res Preamplifier(Black) - Suanqi XLR Cable XLR Adapter Cable XLR to XLR Microphone Cable, 3-Pin Female to 3-pin Male Balanced Shielded XLR Cable (6in) - Topping E70 Velvet AK4499EX DAC Audio Decoder- Bluetooth5.1 LDAC Hi-Res XU316 32Bit/768kHz DSD512 BT/USB/Coax/Opt Inputs RCA/XLR HiFi Stereo Digital-to-Analog-Convertor Sliver --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/514060908-topping-l70-fully-balanced-nfca-headphone-amp-4-pin-xlr](https://www.desertcart.com.ar/products/514060908-topping-l70-fully-balanced-nfca-headphone-amp-4-pin-xlr) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-20*
