The M&K speakers are really designed for a HT system. If this is your primary use then they would be a good choice. The Triad speakers are a little more traditional design and likely better for both stereo and HT use than the M&K. Be mindful that both are not full range speakers and need to be supplemented with a subwoofer. Best results in building a theater system usually are achieved if you use all the same speakers or at least the same brand within a system. Once you choose, plan to stay on the same path or start over completely with something else.
