It is hard to say that a damping factor over 200 is inaudible, because the amps with very high damping factors do usually sound better. The huge power supplies needed to get a high DF also contribute in other ways. For example, my old 125 wpc Audire amps use 4 26,000 mf caps per channel (x 4 in my bi-amped system), while the contemporary Bryston with 200 wpc uses 2 4000 mf caps per channel. Guess which amp starts losing bass at high volume? Not the 125 wpc per channel one.
Damping Factor - Interesting article
Benchmark Media published interesting article on Damping Factor. I already knew that it does not make much difference for the damping of the membrane, but low output impedance is necessary to drive changing impedance ot the speaker (ideal voltage source). According to this article DF=100 produces about 0.5dB variations typically, while DF=200 reduces it to 0.1dB. DF above 200 is inaudible.
