I'd like to be able to support both my in-ear monitors at 18 Ohms or an external headset at 600 Ohms. I'd settle for just the in-ears to start though. > If these are too much for your ears, there is the 8-pin DIP LM386; Jameco= has the LM386-3 which can drive up to 700 mW at 8 ohms, for $0.79 each.

I find it utterly astounding whenever anyone else is interested in what I'm doing. It's not that it never happens, it's just that I tend to build things to make my life easier, and that other people's interest is never really part of my thought process. Probably why I haven't made some super fancy gadget that's taken over late night TV infomercials! Thank you!
