I got two of these when it was at $200-- one for use, one for a backup in case it stops being manufacturered. I'm considering a third backup at the current price. That's how good this amp is. I also have the Apogee Groove at twice the price, as well as a Dragonfly, and this DACport handily beats both. If you want a tiny dac/amp that runs off USB power and works from Android phone, there's no better option. If you found one, let me know.
