Keilschmeil,
Corresponded with Mark by email as stated above on Dec. 14, 2009. I am not that familiar with the entire Melos thing as I only recently picked up the Melos MA-333 preamp. The tech is changing the attenuator for me. See Mark's email to me below:

Thank you. You're in. We are late but 2010 has Melos opening with the only authorized upgrades and center in the world. They will email you once it's open.
Sincerely,
