#25 Gustard A20H: $752 HiFiGo eBay
Pros: A rated 2.4 W balanced into 32 ohms and 264 mW into 300 ohms is enough for planar magnetic and high impedance headphones alike. Inputs include USB, I2S over HDMI, AES/EBU, coaxial and optical, with RCA and XLR line outputs and a 60 step relay volume control. Audio Science Review measured 103 dB SINAD, clean enough for nearly all listening.
Cons: Its 103 dB SINAD trails many cheaper rivals, and the Tanchjim Luna rates higher with cleaner measurements for a small fraction of the price. There is no Bluetooth input, and at 6 kg it is a very large and heavy unit for what it delivers.
