When it comes to technical orientation, I am probably more capable than most. I have not only designed analog amplifiers, I have designed and built computer CPUs, computer systems, and personally written millions of lines of computer code. Nevertheless, when I go out to play my music, I really don't care to contend with a control panel that looks like the dashboard of the space shuttle - particularly after I've imbibed a beer or two. Many modern amps have literally dozens of knobs, switches, interface protocols, and connection options. Naturally, these must be accompanied by user manuals hundreds of pages in length.
