You are asking a question that may be answered in a way not serving your best interest.
There are many pre amps out there.
Mark at rogue engineered the M180s to work well with the Rogue 99 pre amp.
You may find many good looking pre amps winning over the harts of the well intended some making the choice on looks first.
Most are eager to recommend their favorite pre amp in their system to you.
But I would ask how many have actully heard the Rogue 180s and Abed a Rogue 99 up against pre amp b in that system?
and then what happened.
