symphonic line kraft 250

Hi folks, does anyone have experience with Symphonic Line Kraft 250 power amp? I've heard (from some German reviewers) that this one (especially in the monobloc version) has an excellent sound (powerful but very refined with silky, airy hights). If that is the case, I would consider to buy this power amp in the future to replace my Accuphase A-50V, because I think more power would be beneficial in my current system (Dunlavy SC-V speakers). A complete stressfree solid state amp with a refined spacious sound (like well designed OTL's) is on top of my wishlist.
