Oh, I don't know, Panomaniac, I'm just a fool for complicating everything--kind of my approach to art projects like this.

Seriously, the iPod provides a decent poutput line level. However, I do plan to run two SI boards in the box, so I'm splitting the signal in half, and I assume that will cut the input level to each board somewhat. Is that correct, or can I ignore this?

Probably a bigger concern is the CD player. As far as I've been able to find, there is no available decent portable CD player with a line out available these days. To my ears, the Sony I'm using sounds better when its output isn't near full volume, which means the signal level is pretty low. I just picked up a PlayStation 1 to rebox into a real CD player, but it seems a lot of reengineering would be required to make it run on battery power, so that's a long way off for me.

Plus I'd just like to get a better handle on the op-amp thing as a learning experience, and maybe use it as the basis of a little more complex equalizing to get the TB 4" Bamboos sounding their best in this small and crowded box. Like I said the Greg Ball GB-BX what was what got me thinking along these lines in the first place.

As always, thanks for everybody's suggestions.
