Magico A1 or Sopra 1 or Marten Oscar Duo

Hello,

I am looking for a new speaker to replace my 803d3’s. I don’t need the lowest frequencies in my 4 by 6 meter room. So, what would be a good replacement?

Can someone  tell me about differences in sound?

My amps are: pass labs xp12, Bryston 14bsst2

cd: simaudio 650d, Bryston bcd3.

thanks!,
