I also agree with post by @mclinnguy … it is difficult to answer until his additional questions are answered. Your speakers and amplification are solid performers. However, I cannot comment on the theater processors you are using for I do not have any experience with these units. I also recommend starting with the digital front end. If your budget is $30k, I would spend half on a DAC and half on a streamer/server. My favorites that get you to near world class performance are a Mola Mola Tambaqui or Bricasti M1 with an Aurender N20, preowned W20SE or Grimm.
What should I upgrade next in my system?
Would a music streamer be the best place to spend money?
