Please help optimizing my equipment.

Currently using a Marantz SR7005

                           Accom GFA 555ms (to power 2nd zone of wired speaker that are no longer needed)

                              KEF LS50 anniversary ( for turntable and Roon streaming)

                               MHDT Orchid DAC for streaming

                                iMac mini for streaming  

                                Oppo 105 (just for CD’s)

                                 SVS PB12 NSD sub (for the LS50’s and streaming)

                                  Victrola stream carbon  (for Sonos and KEF LS50’s)

What im trying to accomplish is best sound utilizing the Adccom amp and existing speakers with my turntable and streaming   

I want to eliminate the Marantz,since i dont run it when watching TV   ( I’m using a Sonos Arc and Sub)

What are my best options ? Yes i know the Victrola is sub par for stream  but, i like that option  

TIA  for any advice
