About the Mont Blanc E12

The FiiO Mont Blanc E12 is a portable headphone amplifier known for its impressive power output and audiophile-grade sound quality at an affordable price. It measures approximately 124 x 65.5 x 14.5 mm and weighs around 158-166 grams, making it roughly the size of an iPhone 4. The device features a robust build with a brushed aluminum finish that is durable and resistant to scratches. It is powered by a clean battery and uses a combination of OPA1611 and LME49600 operational amplifiers, with an ALPS potentiometer for volume control, ensuring low distortion and high fidelity sound reproduction. The E12 delivers over 880 mW of output power at 32 ohms, making it capable of driving demanding headphones such as the Audeze LCD-2 and Sennheiser HD800 effectively. It includes useful features like a gain selector (0 or 16 dB), bass boost, and a crossfeed switch designed to improve the listening experience, especially with older recordings. The amplifier is praised for its tight, well-controlled bass, detailed midrange, and a forward sound signature with good PRaT (Pace, Rhythm, and Timing). It has a signal-to-noise ratio of about 110 dB and a very low total harmonic distortion (THD) of 0.003%. The E12 runs on an 880 mAh battery providing around 12 hours of use per charge, with a charging time under 2 hours. It is highly regarded for its sound quality, build, and value, though it has been discontinued and replaced by newer models like the E12A and A5. The E12A variant offers improvements such as longer battery life (>20 hours), a slightly lower power output (420 mW at 16 ohms), and a more refined bass boost implementation. Overall, the FiiO Mont Blanc E12 remains a respected portable amplifier for audiophiles looking for powerful, clean amplification in a compact form factor.
