ok, good start, you might keep an eye out for a second MC502.
for more power, that amp can be used in mono, 150 wpc/8 ohms
so, avoid speakers with low impedance dips, it will do stereo 50 wpc @ 8 ohms; 75wpc @ 4 ohms, or 150wpc mono @ 8 ohms (no 4 ohm use in Mono)
gives you a bit more freedom when choosing speaker's efficiency.
