Good to hear you like them, I alway liked the 1038Be and I am sure these are better. The Sopra 2s are on my list of speakers to hear. Do you use an active crossover? If not it would make a huge difference.
I have had a pair of JL E112s in my system for about two years (pre-ordered them) and run the internal active crossovers. It makes all the difference in the world and lets you cross-over higher (60hz-ish worked best for me)
I am looking at the Sopra 2 but am leaning toward the Magico S1 or Vivid B1 (with duel subs). Have you heard either of those speakers before?
