I would have to agree with Pass-Labs XA60.5 or better yet XA60.8 mono-blocs. I had the XA30.8 stereo amp and it sounded terrific with 93db speakers. I seldom moved the meter on it and I played some music pretty loudly ! Don't let the 60WPC fool you into thinking that's not enough power . Pass designed these amplifiers with lots of power-supply. They are 60WPC class A into 8 ohms and double into 4-ohms. You should be able to find a pair of 60.8 mono's within your price-range. Many times, Maggies are demo'd with Pass-Labs amps which obviously sound great. Good Luck on your amp-quest !
