Muralman1, this is off topic discussion. However, I went to the website of H2O Fire Preamplifier and checked the specifications before I posted the comments. The preamplifier doesn't have XLR inputs/outputs. I believe you intend to say that some preamplifiers do have XLR inputs/outputs but they do not have balanced circuitry and vice versa.
Please more opinions on Mark Levinson 380s, Pass Labs X1 or Ayre K-5xe!
