No he is not the one. I have seen this comment many times in many forums. I personally feel it bit bright in upper mids too. The R11 is dark, as the bass is quite few dbs above the mid and treble and same is the story with blade 2 meta.I listen to them several times a week, but not more than an hour. more than hour on weekends. I have other things to do. I have Topping D90Le, Purifi with bypassed buffer. Even some people think chinesse equipment is bright I do not see it.
Personally I consider them as many people "not bright" even DARK speakers despite flat curve.
You are first person to call them bright.
Maybe it is room decoration or some amp helping in "brighntess". I do not know. Even on Youtube via headphones they are dark. Reference series on youtube is not Dark but R is dark.
I like R3.
R11 is a bargain, if you like the blade 2.
