Hi Daniel,
I think you have a really nice set up. If you are happy with it Don't change it. But if you must... from what I have read I think you have gotten some really solid advice. So you have time on your side to research. I am adding a few options to explore.
Rogue is very powerful, Dynamic friendly to tube rolling.

Stage 3 Concepts is a fantastic cable company. They build great power cords. Add this on to any preamp/ amp, its like adding another component.

Add this to your existing preamp and it will most likely give you what your looking for.
