System Upgrades for Streaming

Hi all. Wondering if some of the experts here could lend me a hand. About 3 years ago, I purchased a Rogue Cronus Magnum II, KEF LS50s, Project Debut Carbon with Ortofon 2M Red cartridge, and Peachtree Audio DAC iTx. BlueJeans RCA and Analysis Plus Oval 12 speaker cables. I recently added a KEF C4 subwoofer for movies. System is pretty good for my 800 sq foot Brooklyn apartment. Main room for sound system is 12' x 40'.

I find myself streaming a bit more (mostly Grateful Dead/Phish) and am considering a switch to Tidal from Spotify. If I were to upgrade the system to make it easier to stream via Bluetooth, what's the best method? Apple TV to DAC to Cronus? Is that going to erase any benefit from Tidal loss-less?

Also, what's the next upgrade for this system? Should I be looking into better power supply? A better sub (REL or JL Audio)? Since I don't use the vinyl daily (weekend mornings mostly), I'll probably avoid upgrading that to a Rega/Music Hall, but I could be convinced. Any comments on my cables?
