I owned a pair of these, but never owned any Mc gear at the same time. Klipsch and Mc were often sold together--they are a good match. However, most of the time you do not need the power of the Mc. You could easily drive the La Scala's with a 3 watt SET, which is what I would do if I still had mine.
If you have not heard the La Scalas, you should before you buy. They are extremely dynamic--one of the best in that regard. They will play louder than you want or your neighbors or pretty much anyone in the same zip code. However, their ability to do these things does give them limitations. They do not go that low in frequency response. They roll off quite a bit at 30 Hz. Klipsch rated them only to 35, but they are better than that. They are also somewhat soft in the top end. Lastly, they lack micro detail and imaging (or soundstaging).
What they do well--they do very well. If dynamics and the ability to play loud is your top priority these speakers are very hard to beat and I really doubt can be touched for their price. If do listen softly and listen for imaging and micro-dynamics, then I would not recommend these.
