CAT amp/preamp & Sonus Faber Stradivari

What do you think of the combination of CAT SL1 Ultimate preamp, JL3 monoblocks and Sonus Faber Stradivari speakers? I haven't found much info on such combination on the forums. Thank you for your answers.
I belive one of the Branimir's friends uses this combination. You have o ask him.
Just wanted to let you know that I extensively evaluated the Strads with my SLI/JL2 combination as I used to be a huge Sonus Faber fan (still am I guess!) having owned Guarneris and Amators. However, while the Strads were good, I did not find them to have sufficient transparency and micro-dynamics. I have subsequently purchased Ascendo System M which I find to be significantly better in every way. See my comments about them in their discussion threads. Hope this helps!
