The 97db at 16ohm spec will be a great match for the ML2's and likely a better fit than 89db at 8 ohm. Of course all depends on the speaker and listening volume you require. With my ML2's I am using Reimer Teton's at 95db and 4 ohm and the amps control the drivers very will with all the volume I could possibly want.
