This might be appreciated here

a little history
First cycle distortion - Graham, what is that? millwood «i hold a lot of respect for Graham, as well as any member on this forum and I think if proven true, FCD can be a revolutionary step forward in our understanding of audio and human hearing.» The many faces of distortion Graham Maynard «To me 'linearity' has always been 'continuous proportionality'. That is a fundamental definition that was not written by me, and it is not wrong. Amplifier amplitude linearity can be measured in time isolation to specify a good thd figure, and yet reproduction can still sound poor with dynamic waveforms because of the reactive delays associated with its internal stabilisation and NFB circuitry. For those who don't deny its existence, this is where First Cycle Distortion observation will show on the simulator which amplifiers are capable of clean dynamic reproduction; like the JLH class-A is within its working capabilities. If all of this really has been widely known for many years, then I wonder why the argument (and the inappropriate name calling/mischeivous postings by some !) ?» I tried to answer the question: “First cycle distortion - Graham, what is that? "By its numerous examples in this and other branches (threads): Musings on amp design... a thread split. and even wrote a small memo since I speak English poorly, and use the Google translator, I also saved the Russian text |

What do you consider to be a good number for propagation delay through an amplifier, and what do you consider a good method for measuring that?

So what? Everything else i.e. the rest except of the non proportional 0,000000000000000000000000000000000000001 % of the "song" is just exposed to a constant group delay corresponding to the propagation delay of the amplifier - you like storing a song on a tape, LP or a CD but just a "little" shorter duration. Let this go. It's a mirage that is not worth to chase. //
