Redo the room. If the ceiling is low (hope it's not), use GIK diffusor/absorption. 36' long by 25 wide. Study up on ideal wall construction. Stop fighting this if you will be in the home for a while. Bring in a EQUI-TECH balanced power wall unit and run a couple of dedicated lines. Accomplish this and you can begin to consider components. Believe me, quiet power gives something no component can deliver.
Does an upgrade make sense?
I may be coming down with the upgrade bug, and I’m open to suggestions. I’m quite happy with what I have—excellent imaging, musicality, dynamics. Maybe I could use a little more depth (left right is fine and speakers truly disappear), and maybe a touch more dynamics.
Almost everything I listen to is Qobuz streaming or hi res and flac files from a NAS (hard drive). My system:
Cambridge 851 Streamer/DAC
Bel Canto Pre5
Bel Canto Ref 500 monoblocks
Dali Mentor 6 floorstanders
Everything sits on maple plinths, Gaia iiis, or pucks.
Cabling is mid range Morrows. I previously had Kimber KS1116s but sold them as the Morrows sounded just as good, on the current set up.
What do I need to get more of everything? Speakers? DAC, Streamer? Amp?
