I would have to agree with JohnK. Tom, you mentioned "that the average listener may not be able to hear the dfference" and that you hear those distortions at reference levels. Personally I know that I do not turn my system up to ear bleeding levels, ever. I don't see the need for it and for those that do turn it up to those levels, I would be surprised if they kept it at that level for extended periods. I feel the trap that most of us get into is that we feel that there is not enought power in our system when, as JohnK pointed out, we need to use the power we do have or pay for the power we are waisting. I would go with the speaker addition. Then, if you do hear distortion, and with money saved, go with the M200's for the centers in the future.
