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!

what is a particular reference that we might listen to ?

by the way, in my line of work ( retired ), government work was super high precision, hope your gps works well. ha.

Perhaps upgrade the Morrow Audio cables, I tried them and thought they lacked detail, there’s better available around the same price range.
@tomic601  hi there,  thanks!  No offense meant with the government work. I have a lot of respect for the civil service and the scientists who work for the govt. My vaccine is one example.   Also my computer science research in grad school was funded by DARPA.  So have a lot for which to thank the bureaucrats. 
Two new tech products I have recently found transformational in my 50 years of trying near every damn thing, including MC's spring thingys. 

1) equipment and speaker supports from critical mass systems.  CS2 and LS2 respectively.

2)audiophile switches.  These clean and reclock your ethernet signal.  Three I know are Melco, SOTM and uptone audio's Ethernet Regen.  The last is the cheapest.  More than one in series is a further upgrade. I use three. 

Happy listening.
