Korie, the 310 came out more than 10 years ago and the features are quite dated, of course. If it's still in good operating condition though, it should do the job as far as basic amplification goes. The 60 watt two channel driven rating(and HK is typically somewhat conservative with its ratings)would be sufficient to drive average sensitivity speakers, such as the M3s, to slightly over 100dB on brief peaks. This should be plenty for most uses.

Enjoy the music, not the equipment.
