sdl4 - an outsider you might consider is Morrow. I ended up outfitting my studio with Morrow ICs and speaker runs. My comparisons weren't terribly extensive, but I did read widely and compare against some old Kimber, Straightwire, OCOS, Mogami, MIT, Magnum, and Audioquest, all from the 1980s. I landed at Morrow's "4" series as their cost-effective sweet spot. Morrow direct markets with periodic discount sales and a generous return policy.
If you do give them a try, or if anyone else here has tried Morrow, I am interested in your reports. To my ear it meets your "relaxed, detailed and natural" criteria at a modest price.
