I think I am in apparent contradiction with Rich--I would look at the electronics first.
I ran my CD-25 (Shanling CD-S100) with a 70s-vintage HK 930 2-channel receiver (and DH Labs Silver Sonic cables). The 930 is widely regarded as the best-sounding receiver HK ever made and the later HK products I have heard cannot match it. The sound was not too bright and edgy, and this was in a large room with no sound absorption--curtains, upholstered furniture--at all.
I know what you mean about detail, though. The Shanling player can sound very detailed. It was when I swapped in an upmarket power cord that I realized that detail was a tad artificial. The new power cord let me hear closer to the back of the hall. (This is not to say the CD-25 is a bad buy. In its price range I think it is the best.)
If you can swap in an amp you know to sound smooth and warm in another system, that would tell you something about the source of the edgy brightness you hear in yours. My own preference for a movie system would be for solid-state amplification. I have not heard tubes give the slam I feel is needed for special effects unless they cost a lot. SimAudio, Bryston and Audio Refinement are names that come to mind, and I have heard them all sound warm and smooth. Creek is another.
That doesn't mean your speakers are not contributing largely to your edginess, but to me it makes sense to start troubleshooting upstream. Another important factor is room acoustics. It is IMHO better to have a bright-ish rather than an overdamped room, but carpets and some absorption in the corner areas have removed excess brightness for me.
