The NAD 2200 was a great amp for the money. They have good power but don't especially like low impedance. With a pair of reasonably efficient 8 ohm speakers, I would not hesitate. I'm not familiar with the I.Q. speakers you mention. There is a part that fails on the 2200, I can't remember specifics but it will cause a channel to intermittently drop out. Mine did this after some long hard use but you will want to make sure all is well before buying.
