Bruce, being an owner of either of the two units probably wouldn't be helpful in answering your question. The transparency of each in amplification would be a given and the question would simply be one of the relative maximum power capabilities. Although the difference between 125 watts and 200 watts appears large from just the numbers, the logarithmic nature of the calculation of sound levels shows that the difference is only 2.04dB. For example, if a certain momentary peak could be played at 110dB using 125 watts, it could be played at 112.04dB using 200 watts. It's highly unlikely in the real world that this would be significant, keeping in mind that at a comfortably loud average listening level the speakers will be using about 1 watt.
