I have been meaning to post since purchasing a pair of Kensai speakers. I connected them to my Naim Superuniti in place of the PMC DB1i speakers and immediately the sound was transformed. For the first time, having tried and used many different models of small speaker, I could properly hear vocals and understand announcers and newsreaders on talk radio stations. Music was full range and very evenhanded with a surprisingly believable and extended bass. I had fairly recently added the townshend supertweeters to the DB1i's which certainly opened them out and improved all aspects of their performance but the Kensai's are still way ahead of anything that that combo could do. So all in all, they're a bargain. Friends who have listened have been very impressed. I can hardly imagine how they can be further improved with AudioSmile supertweeters but I assume there is even more to be had with the addition of those. I'm interested in what the tweeter might be able to do in conjunction with my Naim Audio S400 Ovators. I was reading a White Paper on the Ovators and their BMR unit which Naim published a couple of years ago. It mentions among many things the pattern of sound coming from the BMR. So I would guess that the supertweeters would take things further there. Anyway, thanks again to Simon for the speakers and your help and info. :)
