I ran some 461s straight in to the DA-P1 for years and managed to get some great tapes. (Most of the time I would run my D-8 into some Schoeps or Neumann set-up and the results weren't much different than what I got with teh 461s>DA-P1).
Don't use the limiter. I never have, and I have never had any type of overload problems. Also use the -20db pad.
