No, they are different, but both have ribbon tweeters, and they have slightly different specs. Ascend is more well known than Philharmonic Audio, but you're not going to go wrong with either choice (and both are highly regarded). If curious, talk to Dennis Murphy at Philharmonic Audio.
I too have heard great things about KEF and Warfedale, but haven't auditioned their speakers. Let's face it, there are a lot of really nice speakers out in the wild, and probably many of us would be very happy with dozens of them.
