"own four customs, a Weigle, Landshark, Rob English, and Speedvagen."\
Nice! Add me to the short list of people who care about Dynaudios ( I own the Heritage Specials and the Focus 160s ) and steel bikes. Nothing custom in my stable yet, but my daily driver is a Masi 3V, built in the velodrome in 1984 by Alberto Masi (it would seem ) and now restored and repainted by Joe Bell. I've also just built up a Coppi Lugano with Genius tubing. Both have modern Campy Athena groups. If / when I go custom, it'll either be a Speedvagen ( congrats! ) or a Bishop.
As for the speakers, I am sure I paid a premium to have my Heritage Specials built in Denmark, but that was a large part of their appeal for me. Transparency matters.
