I got to hear the Sopra 2 and 1 at my dealer yesterday. The speakers were powered by the Cary SLI-80 tube integrated running in Triode mode (40watts) .I was never a Focal person (except the out of my league Utopia line but these are special. The stand mounted and floor mount speakers demonstrated tight and defining bass not boomy. A pleasant midrange and the top end is not harsh like those focal speakers I had heard in the past. I asked and the speakers have about 200 hours on them. To sum up my experience, rich, clean and transparent . The 1's play a lot bigger than they are.
