I have owned both the A20MKII/A300 and the Primare A30.1. I loved the Primare A20MKII. For the money used I doubt it can be beat. The MF wasn't as good a match with the speakers I was using (GR Paradox 1s, Linn Katan and Quad 12L). I thought the A300 sounded detached and just not as sweet sounding as the Primare. Imaging is rock solid as well. Bass seemed leaner but tuneful.
