LOL...I am a salesman. Just not audio stuff.
I know a lot about the R and Q series because I lusted after the Uni-Q since I first heard it back in the 1986 time frame. My youngest son (who I refer to here as a fellow KEF owner) wasn't even born yet but I had two young kids and couldn't afford KEF. I opted for a pair of Hafler 200 stand mount then. As I was telling my younger son about that ordeal about 3 years ago now, he had already begun going through the stages of upgrade, from a HTIB BIC America system to a Sony, and Polk. He bought me a pair of KEF iQ10's on closeout as a Christmas gift, and it was "game on." He bought himself Q300's and I liked them. I couldn't have the same (dad has to have better), so I shopped R300 with him in tow and came home with R500.
It's been back & forth, mostly me buying for myself and him, him buying...what SWMBO allows for him.
While of course it's the KEF sound profile that I truly enjoy, part of the attraction is the styling. For me, the R series is "understated elegance" with the grills on but technically exquisite with them off. I don't care for the copper look of Klipsch, nor a fan of the yellow drivers in PSB and B&W. I do like the sound of the PSB though. I actually enjoy the sound of Paradigm Prestige series too, but the styling is a little to gaudy for my taste. I definitely do not like the plain flat black look of so many speakers, replicating a movie house or nightclub. My listening space is my living room, so I have to look at speakers as well as listen to them, and so do my guests. Some fail to even notice them if the grills are on and not playing. Others notice the music quality straightaway, a few like to see the grills off. I listen to music with them off, and appreciate that other difference between R and Q series, mine have magnetic grill attachment.
I couldn't be a salesman for KEF. When in sales of a particular product, everything they make is good or "the best." KEF subwoofers are not much of a bargain, and only average in performance...or worse. I'm no fan of the T series, they just don't have the panache of a full cabinet speaker. And they sound "average." The Ci5160/ Ci3160 are incredible, the LS50 is too. Reference series is sublime, though others in that price range intrigue me more. So yeah, I'm a fan of what I own and know but I don't sell them and I also know other speakers from competitors are good for different reason and appeal to different people. Nothing wrong with that.
