What equipment should I invest in next?


I think I have a really good setup for my needs (see below). What should I get next to go with my setup for best sound bang for the buck? Am thinking of a PS Audio power regenerator or Townshend seismic platform for my speakers. Anything else o should consider? 
If it helps, I listen exclusively to classical and jazz. I’m a classical violinist, so I hear a bit differently. I want to hear the individual instruments, their separation, clarity and transparency of sound (no coloring of the recorded audio) and the details of the imaging.

Thanks!

Thanks all. Question. How can I tell whether the power coming from my home electrical circuit is clean-ish or not?  Thanks!  Note that I’m not well versed in this area.

Understatement of the week. But that's not the dig. No one is. That's the dig.

Yes a better conditioner, power cords, outlets, etc etc will be better.
Very nice gear!  I've found that the First Watt amps respond well to a decent power cord. ( I run a J2,and an F5) The J2 is paired with an Anticables Level 3. I've noticed a wide,deep,and tall soundstage compared to a Zu,PS Audio cables I've been using.  YMMV. Enjoy the ride! 
You are asking the question... so clearly there is a problem. You are not glued to your listening chair with a big smile on your face. You know there is more. I reach plateaus... where I am just plain happy. So, I recommend being really introspective... what is missing? Is it rhythm and pace? Musicality? Or bass. Your components seem well matched. I will say that you have to put a lot of money into a Phonostage to have good one. But if your analog end sounds much better than your digital end then that could be it.
