HiFiMAN EF100 Headphone Amplifier & DAC @ TechPowerUp

HiFiMAN is well known for their mid- and high-end planar magnetic headphones, but today, we will take a look at a brand-new HifiMAN product, the EF100 DAC/amp that packs quite a few tricks. For one, it is not just a headphone amplifier as it also features an amplifier for speakers, 4 W strong, all integrated into its very small foot print. The topology harkens back to the EF1 and EF5 amplifiers with a tube-powered input stage and a solid-state I/V conversion stage, which brings a lot of benefits over a fully tube-based design to the table and has proven to work very well with low-to-medium impedance headphones. The on-board DAC is the CM102S, and it is alright, but the interesting bit about the EF100 is that it has two analogue inputs as well, one mini-jack on its side and RCA inputs on the back.
