I’m surprised no one has mentioned Magnepans. I have the Harbeth SHL5+ speakers and love them. I wouldn’t describe them as warm, however. They sound very detailed and natural in the mids, and without coloration. After owning Klipschorns, Tektons, and others, these are my endgame speaker. Based on what you said you’re looking for, I think the Harbeth 30s would suit you perfectly.
I also have Magnepan 1.7i’s and LRS speakers. The Maggies have very nice, rich mids. For me, the Harbeths are superior to the Maggies in most areas, but the Maggies sound very nice, and I enjoy switching them into the system every now and then. I would suggest that you’re on the right track by making tonal quality a priority. There are plenty of speakers with a detailed, analytical sound, but I greatly prefer the organic, natural sound of the Harbeths and the Maggies.
