Mytek FTW. I've got three 8X192ADDA's at the studio now, and wouldn't trade em for anything (except maybe a DAD or Prism). With regard to cards, I've used both the Lynx cards and RME cards without fail for years. Currently running RME AES32 cards in all my boxes, but would not hesitate to move back to Lynx if the price and application were right.
