SS or Tube Preamps with Dual-Balanced outputs

I vertically bi-amp; I am looking for recommendations on fully balanced pre-amps that offer the ability to have 2 simultaneous balanced outputs. I am look for a full balanced circuit (some call this quad-balanced I believe).

Currently, I've been using a Classe CP-700 with excellent results for over a year and half. I like the Classe's build quality, separate power supply, air, clarity, imaging, musicality, etc...very much.

What other SS or Tube pre-amps offer dual-balanced outputs
with great imaging and other desirable sonic attributes?

Thanks!
