Membrane motion braking current (Lenz law) passes thru speaker, wire, amplifier's output and the other wire. Would adding 0,002ohm (DF=4000) instead of 0.02ohm (DF=400) to speaker impedance make it sound different (damp/brake better)? Even if we assume 4ohm at low frequencies of 6ohm nominal impedance (1kHz) speaker, we get 4.002ohm vs 4.02ohm. As long as DF is decent (>20) it should be fine IMHO.
Do Harbeth speakers really need a 4000 damping factor?
Just got Harbeth C7ES-3 XD and using them with a "lowly" Yamaha A-S801 Integrated Amp - which with previous speaker (Canadian made Enigma) sounded OK. The Harbeth - are glorious with vocals and even piano sounds good but Orchestration seems somewhat muffled to me. I read that "Harbeth likes to demo with Hegel" (and Sugden?) but also that "Any good Amp will do".... The question is what is a good Amp? Would a Yamaha with 240 Damping factor suffice or really something like the Hegel with 4000? I am mentioning the damping factor specifically since it was such an obvious difference. On paper it looks like this might have a significant effect (assuming to the positive) on the sound. Any first hand experience opinions are appreciated.
