@karmapolice I have been a long time SR user and now an SR dealer that owns the PowerCell 14 in my reference system. It is a huge, huge improvement over the PowerCell SX, with a much lower noise floor and improved dynamics and soundstaging. With the redesign of SR’s EM Cells, they now double their function as both an electromagnetic filter for the power line as well as a supercapacitor to be able to deliver more instantaneous current than the wall can provide. I plug my T+A reference amplifier into the PC14 and have no regrets in doing so.
Let me know what questions you might have specifically on the PC14 and I will do my best to help answer them!
