Musical Fidelity A3 or Marsh P2000 Preamp

If you had to pick, which of these preamps would you choose?
A fully modified P2000 is very hard to beat! anything!
Thanks for the responses. Scdrj- what do you mean by fullu modified and would your answer be the same assuming neither was modified?
The Musical Fidelity A3cr preamp is really something special, not just special at its price but in relation to all preamps, much more so then the "A series" amp and dac, from my personal experience in home.
