#1 Topping A30 Pro: $349.99 HiFiGo eBay
Pros: Audio Science Review measured 121 dB SINAD, so its noise and distortion are inaudible. Topping rates it at 5,500 mW into 32 ohms and 840 mW into 300 ohms, enough power for nearly any headphone, with 6.35 mm, 4-pin XLR and 4.4 mm balanced outputs plus RCA and XLR inputs. Pass-through outputs let it sit in a chain ahead of speakers.
Cons: It is an analog only amp with no USB or other digital input, so you need a separate DAC. The Topping A50 III rates the same with the same measured SINAD for less.
