#9 JDS Labs Atom Amp 2: $129 JDS Labs eBay

Pros: Audio Science Review measured a SINAD of 120 dB, so its noise and distortion are inaudible. A rated 2,650 mW into 32 ohms and 286 mW into 300 ohms drives nearly any headphone, and it offers both 6.35 mm and 4.4 mm outputs. It matches the rating of the Topping L50 for less and adds RCA preamp outputs for powered speakers.

Cons: It has no DAC, so you need a separate source. Its inputs are RCA and 3.5 mm only, with no balanced XLR input, and the Topping A50 III rates slightly higher for a bit more.
