Jeff Rowland Design Group Conductor Phono Stage

Hello! I am considering this phono stage and looking for one of you who may have direct experience with it.  If so, please describe your experience with it and your thoughts about this product.  

Among the other products I am considering are the Pass XP 27, Van den Hul Grail,  Brinkman Edison Mk II, and Zesto Tessera.

Thank you in advance for your comments.
