Trade: Amp design and repairs.
They really are an interesting company. The old reference series were great (104 a/b, 107's, etc.) I think the 104/2's were great sellers and good speakers but started down a path of "flubbiness". By the mid-90's the stuff was awful. Just downright awful. Their uni-q drivers really sucked, they were harsh and didn't seem to give any benefit, whereas Tannoy (who also had some bad years, don't get me wrong) at least gave you that high dynamic impact...thing.
I remember hooking up Q30's, 50's, 70's, they got worse as you went up the ladder.
My understanding about the new holding corp (and, don't skewer me for being wrong here, it's just what I heard at a fairly well educated dealer) is that the new owner quadrupled the R&D budget, threw out the old designs, and that's where we got the Muons, Blades, LS50's, and the models that have sprung both up and down from there (R series, reference series, etc.) They do seem to have some serious re-invigoration going on. But most importantly what they have back is personality.
I've never heard the maidstones but my concern with that was that they were at the tail end of the "kef dark age" and that uni-q driver in the top cabinet was just ball-sucking bad.
I really love the Uni Q drivers in my R105.3's! I'd find it hard to go back to normal separate tweeters... most of the sounding-different-depending-where-you-sit-and-what-angle-your-head-is-at is eliminated! They are not in the least bit harsh....
