"With their gorgeous, drop-dead looks, exacting build standard and technological prowess the KEF Reference 1 loudspeakers are a rare but refreshing combination of beauty and brains.  They really do not have any weaknesses save that they are brutally honest in regards to source material and may not sound their best with poorer recordings.   Their superb resolution and extraordinary imaging will present the performance like no other stand mounter and will totally immerse their lucky owner into the music.  These certainly are a Reference by which others will be measured"
