Germanboxers, I ran my Capitole MKII CDP directly to several amps(YBA Passion monoBlocks, ARC VS110, Cello Duet350, Krell KSA80, ML333, ML335). I've tried balanced and single ended configurations for several months now.
My conclusion is that Capitole MKII CDP works a lot better with balanced connections. Sound is globaly more rigorous (in the good sense), more precise, more detailed, fuller, clearer. Soundstage is definitively better defined and more precise. I strongly recommend to go this way. But give it a try first because I experimented a big big hum on 2 amplifiers.
One observation: I recently tried a couple of power cords. Results were amazing with Shunyata Anaconda VX (after the cord remains plugged 24h). AudioAero people don't know how their own CDP can be that good! Strongly recommended.
