Tube Preamp with Solid State Amp?

Greetings!

I’ve seen some folks using Tube Preamps with Solid State Am ps. I’m thinking of doing that with my system as part of an incremental change. I currently have a Parasound P5 preamp with a Parasound A21 driving Klipsch Cornwall 4’s. Will a decent / good Tube Preamp really make a difference in my sound? I enjoy what I have now but really want to experience Tubes in my system. Thanks!
