How do the Elac Uni-Fi UB5s compare to more expensive bookshelf speakers?

I own the Wharfedale 10.1 and 10.2.i heard the Ls50 with ML 100 w, accompanied by audio research preamp and theta transport n dac with aq diamond ic n dragon sp cables, they blew me away, this speakers are capable of giving you anything you connect to them, there's limit of course...
The Elac UniB5 I heard at Axpona last year, connected with Audioalchemy gears n Audioquest cables, they also sound very very good.
So which one to choose? If you have budget and good gear Ls50 is the way to go.this is a quality speaker...well made, well built...The B5 you can't go wrong as well...no matter what they are musical...

Another point to keep in mind is the cost of the stands. They tend to make a noticeable difference in the sonics so you don't want to skimp when buying a $1500 speakers.

Kalali agree, sound anchor has a good stands owner is nice....

I gave the Elac Debut 6s a long audition at home. (Long enough to piss the dealer off.) My thoughts-

Great midrange and bass. 
Very finicky about placement. 
The upper register sounded muffled. Like someone had turned on the Dolby switch. 

The last item was the dealbreaker for me. Went with the KEF Q150. Haven’t looked back. 

I notice that Elac is already on .2 for most of its models. Can’t speak to their sound. Maybe the problems have been fixed. 

You can't hear what and likewise, I can't hear what you hear. Hearing, touch and taste are almost totally subjective.  The best speakers I've ever heard are Quad 63's but that doesn't make them best does it?
