I'm planning to build a PIMETA for use with my future Etymotics. I have some questions regarding portability issues:
How significant are they benefits of using an 18V power supply over a 9V power supply, if any?
If the 18V power supply is worthwhile, what would be a good enclosure for the board and two 9V batteries?
Should I NOT bias the opamps into class A if I'm using battery power?
Any answers or other advice are appreciated.
