Oddly, even white noise can improve intelligibility. One reason so little progress is made is that people have a tendency to accept logic rather than to experiment.
"EQ involves additional stages, capacitors in signal path etc. (some form of signal processing) Let just say that it doesn't add to clarity."
If one is in the digital domain this simply is not true. The digital amplifier simply runs a program and provides gain. Whether the output reflects the input accurately or is modified has no bearing on the quality of the output. A modification can improve or diminish clarity depending on a myriad of factors. I have been experimenting with equalization for years. Trial and error trump theory for most of us at this point, but some bright guy or gal will develop the correct algorithm.
