That was my issue with R as well, all perfect except for narrow dispersion. While 50ish isn’t exactly very wide, and as you mention many other speakers are even wider, with KEFs stellar imaging would be perfect. Erin did compare R and maybe original reference to new reference Meta which is around 50-60 - making it his one of his favorite speakers. Perhaps in bigger rooms at bigger distances/spread narrower dispersion doesn’t matter but us people with smaller rooms do prefer it for it to be wider.You are right here, I just checked the ls50 and ls50 Meta. They both are more or less 50 degrees. In real life R Series was always narrow to my ears, and ls50 meta wide. Never listened to the Orginal ls50s. In a typical Hi-Fi Store, everything else sounds wider than uniq. Hardly heard any hifi speaker narrow as the r series recently. But they image better than everything. You cannot get both on a speaker if m not wrong.
