A 36'x36' square room is your biggest issue to tackle. Not sure what the solution is but this will always be a tough room to get maximum audio quality in. Definitely work on any acoustic treatment recommendations first before moving on to equipment upgrades. Seeking the help of an acoustic professional would be your best investment at this point IMO.
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?
