Starting Over and I need your help

The more I read…….the more I become confused!…..Do I simply need to start over with more carefully selected components?

I currently own a Musical Paradise MP 301 III, Bluesound Node 2i, Omega 7 speakers, and a Rotel RCD 06 SE CD player. To me, this system sounds underwhelming, especially when streaming. I use Apple Music as a source but I am open to switching to another. I only play CDs and stream and do not see myself incorporating vinyl into the mix. Musical tastes are jazz and acoustic. The room size is smallish home office. By the way, I also own a Parasound Zamp that I currently don’t use because I do not have a preamp……should I sell or keep that?

I am willing to sell it all, if needed, to get better sound.  If you were me, what would you change or keep? My total budget would be under $3000 and by buying some used I bet you guys can help me figure out what I should pursue within Audiogon to purchase.

Many thanks in advance for your expertise and opinions!
