#2 Topping A50 III: $199.00 Amazon eBay
Pros: Audio Science Review measured a SINAD of 121 dB, so its noise and distortion are inaudible. A rated 3.5 W into 32 ohms and 760 mW into 300 ohms from its balanced output is enough for nearly any headphone. It has 6.35 mm and 4.4 mm balanced outputs and costs less than the Schiit Midgard at the same rating.
Cons: It is an amp only, so you need a separate DAC. Its balanced input uses 6.35 mm TRS rather than XLR, and there are no line outputs for passing the signal on to speakers.
