Are spendor speakers competitive in sound quality to KEF, B&W, ProAC, Audio Physic

 ARE SPENDOR SPEAKERS IN THE SAME LEAGUE AS THE ABOVE BRANDS?. THE COMPANY DOES NOT TO APPEAR TO DO MUCH ADVERTISING, AND THERE ARE FEW REVIEWS OF THEIR PRODUCTS, IN PARTICULAR, THE MODEL A6R

I know from reading reviews, KEF, B&W have changed their house sound, Audio Physic has changed its sound signature but not as dramatically as the former brands indicted.  ProAc and Spendor  are often described as more the traditional BRITISH sound. I have listened to the above three over the years, but never auditioned either the Pro's or the Spendor in a home setting or audio showroom 

Thank you,
