I also am a Polk LSi15 owner, and I also find it to be superior to the LSi25. Getting that active sub to mix well with the rest of the speaker its a bit of work.
Having said that, I drive my speakers with a Perreaux Radiance R200i integrated and love the sound. The one thing about the LSi15s is that you need an amp with a high damping factor to control the woofer on the speaker, otherwise they may sound a little loose on the bottom end. So, you almost certainly want to drive them with a solid state amp. Prior to having the R200i, I drove them with a Perreaux 200iP. That produced a slightly different sound, one that seem to be, not as neutral, but seemed to have a little bit of more body to it (I'm talking about very minimal differences here). That is a very satisfying integrated amp that won't cost an arm and a leg, and will make your speakers sing.
