I used an X2.5 with Bel Canto's Evo power amp with good results. It sounded best in balanced mode, but has extra gain. My main complaint with the X2.5 was that the volume steps at 3 dB each were just too much. It was either too soft or too loud.
I listen at lower volumes in the evening and getting the exact setting I wanted was very difficult. I had no complaints about the sound.
