DaveFX:
I'm sure you will get solid mechanical latching with the Hosa/Livewire OPT-100 series cables (Standard).? I described how this works in a previous post in this ADAT cable thread.? Once you try the cables I recommend, I'm sure you'll be successful.
Thanks. I must have something wrong with my Safari browser. Only 8 messages were showing here until I reordered the newest/oldest. I missed half the conversation, including your initial post.
