#1 SMSL HO200 eBay
Pros: Audio Science Review measured a SINAD of 121 dB, so its noise and distortion are inaudible. The maker rates it at 3,000 mW into 32 ohms, enough for nearly any headphone including demanding planar magnetic models, with 6.35 mm, 4.4 mm balanced and 4 pin XLR balanced outputs. It accepts RCA and XLR inputs, offers three gain levels and doubles as a preamp for powered speakers.
Cons: It is a headphone amp only, so you need a separate DAC. Rivals with the same rating offer more power, such as the Topping A30 Pro at a rated 5,500 mW. It is a desktop unit of over a kilogram rather than something portable.
