Re: Great post Soundmind.

robert young, I think John Curl just proved my point responding to your post.

As for you Mr. Curl, in the several years I've read your postings, you haven't shown me even once that you have the background I'd expect of an electrical engineer. When the subject was wires, you were preoccupied with the Fermi velocity of electrons (might as well have been with phases of the moon and UFOs for its relevance) and the seventh harmonic of 5 khz background noise (like anyone cares whether the noise is down 120 db or 135 db at 35 khz in an audio system), when it came to our disagreement over preamplifier maximum slewing rate requirements you refused to address my example of typical worst case numbers but instead insisted on referring me to an obscure paper you collaborated on 30 years ago. When it came to transient response and rise time you didn't know that it was directly related to frequency response. When it came to harmonic disortion requirements for amplifiers you were more preoccupied with Cheever's masters thesis on the relationship between different harmonic components than on the absolute threshold you have to achieve in a design to make it inaudible. When it came to Fourier analysis you were completly lost. Ultimately engineers have to deal with mathematical equations and numbers something which seems entire alien to you. That doesn't mean you can't be a lucky tinkerer and design and market fine amplifiers but for somone who used to say he would not respond to postings except for those by degreed electrical engineers, you have one hell of a nerve. I have no indication from what you have displayed here that you have one yourself. If you attended an accredited engineering school in the US and they conferred a degree of bachelor of electrical engineering on you, it would seem to me you have forgotten most of what you were taught.
