I think Steven was talking about the phono input, not about headphones.The headphone output is also perfectly fine if you use headphones with a low ohm rating.
The Sundara closed back, for example, with its 20 ohms can be operated well and the PEQ helps with the individual optimum setting.
EDIT: For me personally, the Wiim Ultra would fit my needs much better if would also allow my laptop to connect to it through USB. Maybe for a future update to the product…
