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)

Ultra-High Performance NFCA Modules: The L70 utilizes the same NFCA (Nested Feedback Composite Amplifier) module as the A90. The voltage-current hybrid feedback architecture, combined with UHGF (Ultra High Gain Feedback) technology, delivers excellent DC and AC performance, ultra-low THD+N, and an exceptionally 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 integrated fully balanced amplifier circuit fits well with balanced headphones and also performs perfectly with single-ended headphones. Compatible with Almost All Kinds of Headphones: The L70 is engineered to power the vast majority of headphones. With high output voltage, it readily drives high impedance headphones. With high output current, it readily drives low impedance headphones. And with low output noise, it readily powers highly sensitive IEMs without introducing background hiss. A Headphone Amp, Also a Preamp: The L70 not only drives headphones but also functions as a preamp. In preamp mode, it delivers the same high performance as in headphone amp mode, and the 20ohm SE and 40ohm balanced output impedance are broadly suitable for various power amplifiers. The full-featured remote control enhances convenience for your use. E70 Will Be the Best DAC for L70: The L70 and E70 share fully matched design languages and styles, and the L70 is suitable for almost all kinds of headphones. The E70 and L70 can be powered on and off via the 12V Trigger interface, allowing the L70 to synchronize with the automatic or manual on/off of the E70
