#8 Topping L50: $169.00 Amazon eBay
Pros: Audio Science Review measured a SINAD of 121 dB, so the amp adds no audible noise or distortion. A rated 2,800 mW into 32 ohms and 540 mW into 300 ohms is enough for nearly any headphone, including demanding planar magnetic and high impedance models. It offers a 4-pin XLR balanced headphone output and accepts balanced 6.35 mm TRS or RCA inputs.
Cons: It has no DAC, so it needs a separate source with line outputs. The Topping A50 III rates slightly higher with more rated power for a little more, and the passthrough outputs only work while the amp is switched off.
