You can reproduce the sound of a piano with a little over a watt of power with certain speakers. 200 watts of power is only needed in the largest rooms with the least sensitive speakers. The problem with blanket statements like this is they do not take into account many factors that are critical to the amount of power actually needed.

Hi, problem solved. I am going to get the new KEF powered subwoofer. I am very lucky that I suffer from confirmation bias. If I think about an read all the reviews on stuff I want to buy and then I finally get it, it sounds Great!. The power question comes from me reading someplace that to reproduce the sound level of a real piano takes 200 Watts. So I will not feel that I am hearing the full experience unless my amps have 200 watts or more. Thanks so much for all the answers to my question. You guys do good work and plenty of it !.
