Balanced Pre for Bi Amping Recommendations Please

Hi everyone......I`m basically an after recommendations for a BLALANCED PREAMPLIFIER with 2 sets of Balanced outputs for Bi amping with 2 Solid State amplifiers.... My budget is around anything upto US$2000 tube or Solid State.....Looking for transparency & Neutrality but great dynamics and bass......
Any recommendations would be much appreciated
