Danyal I have owned the BPT Signature Plus 3.5 for 14 months and it is wonderful. It has elevated the performance of my system across the board. The sound floor is lower as promised with a very noticable improvement in low level detail,ambience, microdynamics and the sense and presence of air and palpability. Many people say you should`nt plug power amps into a conditioner but go directly into the wall socket. Well with this high current design BPT my power amps are clearly better into this unit than uising the wall sockets(20 amp dedicated line). The sound is more dynamic, pure, open and the stage is wider as well as deeper. I have heard very good reports regarding the Walker unit but have no personal experience. By the way I should mention that my BPT is dead quiet in my music room, despite it`s very large transformer I hear no hum.
