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!

Tannoy Kensington GR speakers
First Watt J2 amp
Pass xp 30 preamp
PS Audio Perfect wave DAC and SACD transport

Very comfortable listening chair.

(You seem to have the electronic part figured out already.)

@charles1dad he’s in grad school at Juilliard, yes in violin performance. Went to Oberlin Conservatory for his undergraduate. Main reason he went to OC was because he wanted to do a double degree in violin performance and computer science, but then on his fourth year decided to drop computer science. (I guess he’s just relegated to being another poor musician.)

Actually I’m pretty fortunate. His tuition etc is paid by scholarship, so we’re on the hook only for his apartment. Not bad really. Although I just realized that my expenditure on audio equipment is WAY more than Juilliard! Oh well. Best not to think about it.😂
@ssmaudio,
You are rightfully a very proud Papa😊.
I wish you son a bright and productive career in music.
