meter only says +4. To hit + 30dbm takes about 16 to 17 volts on each
supply rail. No computer offers that much at its pci sockets. And some,
in an effort to be as power miserly as they can be, will have significant,

Driving the average earbud, they can get away with murdering the music &
few can hear the diff. Sad but true too many times.
