I have 2.3's that I power with the MF A308cr separates, an upgrade of 450W>4 ohms from the MF A308 Integrated I had for about 5 months, rated at 300W>4 ohms. I had to do the upgrade; no matter what I listened to, classical to jazz to rock to electronica to whatever, the ease and fluidity of this combination made me constantly want a little more volume. By the time it'd get where I wanted it, peaks would cause the A308 Integrated to break up with a very loud TICK sound from one or both channels. I have to have music loud enough to cause a physical reaction from me to really submerse myself in it, and it took more than the Integrated's 300 watts to do it. But I have to tell you -- the combo of the MF A308cr separates and the 2.3's (with my Velodyne HGS-II 12" sub) is a remarkable experience to listen to, no matter the genre. If you get enough juice to your 2.3's, they can and will improve the quality of your life!
