I have and LOVE Quad 989s. I too drive them with ASL amps, but mine are FIFTY-Watt SETs, the Explorer 805 DTs. My listening room is fairly large at c. 3200CF, but the amps will play the speakers louder than I ever want to listen. I drive them full-range and they have QUITE-ample bottom-octave energy for this lover of big-orchestra classical and film music. I use subwoofers in the home-theater mode. See my System for pics.
There are LOTS of 989 reviews on-line which include amp recommendations; I know nothing of the MC501s.
