Your findings of amp with power conditioner are consistent with mine using a Furutech ETP-309 which feeds a class D Rowland 312 (500W at 8 Ohms, doubling into 4, with 45 Amps peak current). ETP-309 then goes into 20A dedicated service via A High End Performance Furutech PC. I have experienced with conditioner and opening up of the stage with finer granularity, deepening and more controlled bass, greater low level ambient cues, an no deterioration of dynamics nor authority.
Some conditioners are current limiting, and some are apparently not so. The only thing I might suggest is that you move up the Shunyata line with your PC for the amp, perhaps to a Python Helix Alpha or Anaconda Helix Alpha. Helix line has greater control than older line, whith CX line yielding even greater detail and staging than Helix. Moving up the Shunyata line you are bound to enjoy greater staging and authority. Avoid VX variants, they are not meant for power applications. G.
