Actually I appreciate a well-written manual that has both a 'Quick Start – do this stuff' section and a detailed description of the configurations, parameters, and presets. It certainly helped when I picked up a second H8000FW (used) and the previous owner had a very customized I/O setup that I had to edit for my configuration.
You get in a groove with a piece of gear, using a subset of its capabilites most of the time. When you need to branch out (for example, extended MIDI control over parameter values and mapping to CCs), a manual that gets you up to speed quickly is a godsend.
Plus, reading through the preset desriptions can be faster than manually loading each one looking for a particular effect as a starting point.
I'd put the H8000 manual in the – better than most category.
