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.

Read my review of the Gold Note PA-1175 MkII Amplifier  with switchable damping factor. It appears at Dagogo.com

Kijanki, you are a respectful member of this forum, and I thank you for that politeness. Many would become obnoxious at such an exchange, and I would cease communicating with them at that point. 

It seemed to me that you questioned the result directly when you said, "Is it audible? Perhaps for trained ears, but it is not as dramatic as DF=20 vs DF=2000. There will be more sound change from less than perfect driving, than lower damping IMHO." 

My reaction to your comment is that you feel it is quite insignificant. I am telling you that you are wrong; the difference was more on the order of swapping an amp, or as you say, sound change from less than perfect driving (which is a good analogy). 

Regarding the Benchmark products, I am somewhat familiar with the culture of the Benchmark Audio mindset, and I also go against the grain when it comes to such things as the DAC being influenced by cables, or the amp by power cords. Read my reviews of these components also at Dagogo.com 

Some audiophiles, perhaps yourself, find it difficult to accept that there are significant sonic changes in situations where they calculate that there should not be. I'm in no position to argue with you about your prodigious specification assessment, but I am in a position to tell you that if you think Benchmark's sensitivity to cables, or Gold Note's PA-1175 Damping Factor function are insignificant, you would benefit from hearing such things.  :)
