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(Sliver)

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, 4.4 mm balanced, 6.35 mm single-ended, and 3.5 mm 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,
