The sound of HPs are so personal and system dependent. Until recently, my go to HP was the LCD-4, but I would occasionally go to my HD-800 (no S) for a change (but I did this more often before the LCD-4 , when my everyday HP was the 3F). Anyhow, for me the brightness of the HD-800 was too much, especially when I had the LCD-4 to listen to. I thought about changing to the HD-800S, but by the the Focal Utopia (FU) was on the horizon and went with them.
At first I still preferred the LCD-4, as the FU was a bit bright and, at times, even stringent, even though a lot was good about them. Then I changed the wiring loom of my system (interconnects, power cables, distributor strip, ground, etc) to a pretty expensive mid-range Nordost one. Big system overall sound improvement. Also a swap in my HP preferences with the change of system sound. The FU was now wonderful, no longer bright, just articulate, and the base pretty near perfect. Alternatively, the LCD-4 now sounded better as well, easy to listen to and great base, but in comparison to the FU, now IMO somewhat veiled by comparison in overall sound -- and this even applied to base articulation.
So can readily see why the variation in peoples' HPs perceptions, as everything. even for one individual, is so system dependent! Who knows, my next system change may reverse again my HP preferences!
