don't know if there's a way to disable wifi (fyi, i did load the latest 1.45 firmware). i also got this specifically as a power amp...been buying way too many dacs recently. i do like the multiple inputs/BT/echo functionality.
as far as power goes, i'm not happy at 12 watts on standby, but at 24/7/365, it should cost me less than $10 a year, and as far as heat, i can always stick the device on a power strip...if you need outlet level control, they do make powerstrips with switches per outlet. they also make smart adapters with individual outlet controls by app.
When you press the power button, does it turn it off (or at least into the <1W standby) or does it just go into standby?
@estuardo yeah, but convenience and desk space are both worth something too.
