No help with your search, but I was fortunate to meet John Iverson in the summer of 1991, in Dallas. He stopped by an audiophile dealer that I was working for back then. Hew brought by his Eagle 7 amplifier for us to listen to in hopes that we would carry the line. Love the amp as soon as it lit up the Apogee Duettas that we connected it to in our front listening room. Some found it a bit dark, but lord what a sound it produced! He disappeared the next year and has never been seen or heard from since. A great mystery in and of itself.
