Delphi the Paradigms are a way better loudspeaker than the Kef 205 we had both, the difference is the Kef 205 is much more forgiving and in particular the 205/203/207 had a slightly more colored midrange that was in fact quite beautiful.
If you heard the Paradigms at many dealers they might sound really poor unless they were really dialed in correctly, if you heard them at your place the other issue might be that your gear which works wonderfully well with a warmer loudspeaker the Kef 205 would probably not work well with the Paradigms.
If you let us know your room size, matching equipment, musical tastes we can give you a recommended loudspeaker that might work for you.
However, the newer Kef line Ref 3 are similar and sound dramatically better in all ways over the 205.2 that you have, however the midrange on them too will be a bit more neatural, but overall you will hear the similarities.
Also as noted kef is running a close out special on Ref 3 and 5 in rosewood and walnt that makes them espeically tempting.
If you are in our neck of the woods or can fly into our shop we have the entire Kef Reference line on display as well as most of the Pardigm Persona line as well plus a lot of other great loudspeakers.
