Easiest solution is that one of us Head-Fi'ers (or even a collective) collects and collates all this information in OOWriter (or M$Word for Micro$laves) gets the copy to David for approval and then simply saves this as PDF (and e-book) and places it for free download of for a small donation to Head-Fi. And of course update as things change.
It may even be good to collate other reviews (Headphone Amplifiers, DAC's etc.) into the same book. So to speak a HeadFi Bible...
PS, I'd help, but I'm jammed out as is.
