#12 Soncoz SGA1: $649.99 HiFiGo eBay
Pros: Audio Science Review measured 118 dB SINAD, so its noise and distortion are inaudible. It offers 6.35 mm, 4-pin XLR and 4.4 mm balanced headphone outputs, RCA and XLR inputs and outputs, and a stepped electronic volume control, with 840 mW into 300 ohms for high impedance headphones.
Cons: It is an analog only amp with no digital inputs, so you need a separate DAC. Soncoz rates it at 420 mW balanced into 33 ohms rather than 32, which drives most headphones but is modest next to the Topping L30, a higher rated amp that costs far less.
