Has anyone heard the Tannoy XT8Fs?


Hard to find info on these speakers, but they look like they are capable of delivering that "Live" edge of your seat kind of sound I am looking for.  Great imaging, powerful low end, forward mid range and transparent top end.  Even the XT6F may suffice, but I think I am after a larger speaker with a little more force.  Wharfedale Reva 4s are not delivering for me in any of these areas, especially in the mid low end.

Thoughts?

Thanks for the response, much appreciated.  I am pretty convinced that these Tannoys are the next step for me.  I currently have a pair of Wharfedale Reva 4s that I am not thrilled with.  Now I just have to figure out how to get a listen to them.  Finding a Tannoy dealer has proven to be pretty tough.  Looks like I will have to either go into the city one day (I am in NJ, but it's still a day trip) or buy them on Amazon.
yes, had a listen looking for new speakers- heard them on two occasions in two different rooms and supporting equipment.  
bass was overblown / boomy and the treble was noticeably edgy, crispy and the upper midrange was unrefined.  
The XT6F are far better sounding and I could have lived with them.  
Mid range was more refined on the 6’s too?  Obviously the highs were still edgy and crispyz
