I believe the Resonessence Mirus can do 110/220 volts and does DSD and PCM beautifully. I considered this DAC very carefully and auditioned it for a week and thought it was one of the best I have heard. It also has an SD card reader on it so you can load music onto a 128G SD card, slide into the slot and avoid all digital jitter from a transport or a USB cable. It is definitely in your price range. The designers of the Sabre DAC chips decided they know their chip better than anyone else and built this DAC to prove it.
