I keep reading trying to tame the Spatial speakers on bright recordings. Well, you can't in 40 years in this hobby no matter the format, but let's use vinyl, they had many recordings that sounded thin and bright and others that sounded compressed and dark with bass like mud. No speaker I owned ever changed the way they sounded. So the bane of Audiophiles we want recordings all to sound great but that will never happen. My M3's Sapphires can sound warm and sweet, then another recording brighter with much less bottom end, and that is the way it should be. It's not the speaker causing it, but the recordings themselves. Some recordings sound dynamic and others sound flat and not much microdynamics, those, of course, are the current recording of today and the really the past 10 years that are overly compressed for loudness. If all recordings are that way then look at your room, cables, etc, or just the type of music you enjoy is recorded that way. But in my year with my M3's once broken in that is a wonderful musical speaker with the only limits to the music played and its production sound quality, and setup.
