and a 4th here, but I suspect a few more on here ;-)
For those that don't know, 3 Sad Bastards is the name of a HiFi podcast on Spotify where 3 Australian audiophiles discuss all things HiFi of course..
I was listening last night and this episode came on: https://open.spotify.com/episode/27X3uuaNeQdadQi90JMql9?si=VmXqj-6bTR-Jn9VVOcr1Uw
They had a guest on, Roger Sanders of Sanders Audio Systems. He reckoned that the minimum output of an amp should be around 500W otherwise clipping would occur. I know this was discussed on a thread a few weeks ago on here, but I can't find it now. I didn't really read that thread, but I am aware of calculators that seem to provide sensible results. Sanders speakers are Electrostatic and probably have horrible impedance curves, but he seems to be using the same logic for all speakers types.
Anyway, he also said that his statement is easily proven by putting an oscilloscope across the speaker terminals and where the wave gets clipped it shows that clipping is occurring. One of the sad bastards said he has seen the same on a pair of Zingali's ,a 90db+ sensitive speaker that he was powering with a 50wpc amp and possibly an easy load, but I haven't checked.
Just wondering if anyone else has tried such things and had similar results?
