Indeed. +4 dBu is nearly 3.5 V pp, you can't expect much more
from a single 5 V power supply.

A decent 'pro' line out will be able to drive something like
+20 dBV (10 V RMS) into 200 ohms. That's 1/2 W.

It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
