Hi Luna. I'm assuming you want to improve your sound, not just change speakers-because you're 'bored' with them.
Judging from your system notes I'd say your biggest improvements would come from investing in some conditioning and isolation for your digital, and your preamp, along with a power cord like an MIT Shotgun AC1, or better, for each. For your amp, try to find an MIT Z Stabilizer or Z Stabilizer ll to plug into the adjoining receptacle of your amps power cord plug in. If you would like any details feel free to ask.
