Update - the Symphonic Line Kraft 250 monos have been in my system for two weeks now. While they didn't even have 100 hours on them when they arrived and so are still breaking in/settling in a bit, I can say that they are stunning with the Salon 2s.
Detailed high end without fatigue, amazing dynamics and micro-dynamics, extended powerful bass without bloat or boom , plucked instruments sound like they're really being plucked, and vocals are smooth without being euphonic. Fast as all get-out too.
Really though the best thing I can say about them is that they simply produce the music so that you can listen to it without hi-fi considerations intruding into your consciousness - I know that sounds a bit New Agey but I don't know how else to say it. I also don't know why they aren't better known over here.
Actually I can kinda guess even though I'm no marketing expert: no USA advertising or show appearances, confusing English-side website, odd nomenclature for gear, and Mr. Gemein's apparent penchant for not providing the kinds of technical measurement we Americans crave. Be advised for example that the nominal 250 watts into 8 ohms output designation is essentially meaningless; these puppies drive my Salon 2s louder than my Plinius SB-301 with a stated 310 wpc does.
Despite all that, the product is "until death do us part" incredible and is well worth investigating in the top tier of solid state amplification. Thanks to Klaus Bunge, the Symphonic Line USA rep (and Odyssey Audio principal), for alerting me to their availability when I called with an inquiry about the history of the SL tube pre-amp I ended up getting. I thought he was over the top when he gushed on and on about the Kraft 250s, but after two weeks of listening to them I can say that his enthusiasm was entirely justified.
