I hope in the end everything worked out for you.
I see you have a Doepke DFS. Amazing upgrade I installed one too.
Another great upgrade were the HiFi Tuning Supreme 3 fuses I bought from Audio Foreign Office. The result was equivalent to upgrading to a Special Edition of the equipment.
I bought last week a pair of Zu Omen II for a friend of mine and had a great time with the folks at Ajasom. I have had bad experiences with 2 retailers in Portugal Ajasom and Audio Foreign Office are not among them.
