The Neat Elite Classics were demonstrated at the Bristol Hi-fi Show last year, I am fairly certain with naim amplification - possibly a SuperNait 3.
My music buddy was looking / listening for a new pair of loudspeakers, and out of all the models we heard in that price range, the Neat Elite Classics were our favourite of the day. The only reason he didn’t buy a pair was because he upgraded his amplifier first and that improved the sound from his current loudspeakers so much he didn’t feel the need to change them.
If I was looking for new loudspeakers myself, they would be top of the audition list - though with my recent spend on the 300 series and the improvement the iBLs are showing me, that is a long way off!
