Good morning Kren,
Here is our take on the Paradigm vs Kef shootout, both of these are great loudspeakers.
Kef throw a huge soundstge, very clean and natural midrange, good treble detail, very tight bass.
Paradigm, more holographic soundstage, greater clarity in the treble and midrange, very tight bass.
In a direct shootout we would take the Paradigms, however, the Paradigms require a bit more system matching. The clarity of the Beryillium drivers is amazing but does require a wamer voicing before they sound magical, vs the Kef which tends to sound great on a wide variety of electronics.
The T+A gear is spectacular on most speakers, the T+A sound is slightly warm in the midrange, smooth top end, a very wide and deep soundstage, excellent information recovery, tight but a bit on the warmer side of bass, extremely well designed, beautifully made with usually an upgrade path
Hope that helps.
