2nd what Goodcooker said. I got one of the first warm mod 661s Doug made, but it was after the 661 had been out 3 months for the same reason. At that point, hearing nothing but positive things about the deck itself, I felt it was safe to order from Doug. (worth pointing out that dealers who are also authorized to repair can fix gear they sold that's covered by a warranty and get reimbursed. Only warranty issue would be attempting to get service from another dealer or Marantz service itself).
