Just received a pair of these and so far:
-bass lacks the character of the DBR-62, looking again at the measurements the DBR-62 there's about 5 more Hz of extension, but as I've previously talked about, the DBR-62 also has great bass "character", which I suppose could be either cone speed, cone flex (or lack of), or maybe the surface texture of the CF cone? The UBR-62 bass is accurate, noise-free, but lacking in depth and character. I am not surprised, but disappointed nonetheless as I want to use these for library listening so no sub. Maybe with more break-in time the bass character will improve, only about 8 hours so far.
-they do not play super loud happily, unlike the DBR's which seemed to love power. I was worried I might damage the UBR's despite their 140 w continuous rating. This seems to be confirmed in Erin's review with the compression results? I'll name specific pieces of music and levels in a follow-up.
-they have excellent clarity and midrange, voices are very good, they are enjoyable to listen to at low to moderate volumes, much better than the DBR-62 in this area
-agree with others they fall down a little on "ethereal" highs. not getting some of the atmospheric effects I would expect at this price, but more testing needed since placement is sub-optimal right now.
-imaging could be good, still need to test with the speaker placements set properly- I have them too far apart and too close to the listener at the moment. I will say that I don't think the vertical dispersion is that good. The test data is apparently good so not sure what's going on. horizontal is ok, but I had them upside down with the tweeters slightly above ear level initially and they were beaming pretty bad, it was obvious they were too high. With better placement it's still narrow. Edit: KEF's arrived today and positioned as the Elac's initially were the vertical off-axis image is better. The KEF's off-axis is looking very good, maybe won't "place" instruments so well but they sure sound good atm. More testing to do to see.
I'm about to receive three other speakers to test them against - the KEF LS50 meta's, Monitor Silver 100 7G, and Wharfedale EVO 4.2. I expect the KEF's will beat them on the highs and imaging but let me down even more on bass (the old LS50's did). Not sure what will happen with the Monitors and Wharfes. The Monitor bronze's I tested last year had bad port chuffing and then weak bass if you plugged the port, and highs were simply unremarkable, but I've heard good things about the silvers and a brief test of the previous silver towers suggested they imaged very well, giving Pink Floyd's the Wall better depth of soundstage than I expected at that price point.
As an aside, also just briefly listened to the Fyne 502MP's and holy crap are they good (granted at $6k a pair). I suspect I will find some flaws with more listening but tentatively very exciting, and I dread to imagine how badly they probably measure.
