That wouldn't be a Leema Pulse would it?
Because of Leemas move of premises, this has slowed down me hearing their other products (we do the Elements range in store), but that should be sorted after Bristol.
You probably heard the older Reference range with the square cabinets PP? If so, the current range has changed vastly.
For treble attack/dynamics, the nearest I've found is PMC, which was the OB1i. The new Twenty series will be interesting to see if it has the same characteristic (I have a specific test for it), but I do know the Twenty series is now more open sounding.
For bass, not sure. The Reference has such an even, tight bass with vast headroom, I'd probably have to say the larger ATC boxes.
The Reference range have always been pretty easy to place as well, as they're mostly front ported, and have such little cabinet coloration that they can be place quite close to walls, closer than most speakers at their price point.
Off axis performance is probably the hardest to match. You may find some that will image as well as the KEF's, but very few speakers have the same wide dispersion characteristics of the UniQ driver, so very few compare in this respect.
I've always said one of my favourite speakers is the 205/2. If I had to choose something below those, I think it'd have to be something from the PMC Twenty series or the KEF R series. Both of these ranges are easier to drive than the Reference, so won't need huge amplification in order to hear them as they should sound.
But headroom is one of the key words here. Where the Reference excel, other than a neutral balance, is the vast headroom they have, with the right amplification of course. Their ability to remain sounding the same at louder volumes and still have the same dynamic cabilities is almost second to none at the price point. I've never bottomed out a pair of Reference - it's something you never need to think/worry about.
