You may want to try out the YBA passion integre, which is above the 2K budget but worth the extra cost. At 100 wpc it is more than enough to drive my 88 db Revelation Audio Mistral S6 monitors. I imagine the SF speakers would be a breeze for it and I can assure you that this integre is quite musical ... from my own experience of course ... I pair it up with an audio aero capitole MKII SE.
just a thought.
