@tuffy72561 I think the Super Stroke is a good power cord, especially for its price of well under $99. With that said I find the Oyaide Black Mamba V2, TUNAMI GPX-R V2, Furutech SO22N, and Cerious Tech GE to be better, and kind of all in the same league, of course, the power cords I just mentioned are in the price range of $275 to $350.
I'm hesitant to attempt to describe the sound of each power cord because quite frankly what I hear in my system is going to most likely sound different in your system.
I have owned or had in my system until broken in all the power cords you listed above. I would say the upper-level power cords are the Furutech DPS -4 which might be better suited for digital gear and the Cerious Matrix that I believe would work on all components.
If funds ($) are not readily available I wholeheartedly recommend the following; Oyaide Black Mamba V2, TUNAMI GPX-R V2, Furutech SO22N, and Cerious Tech GE.
If this helps, I did not like the Black Mamba on my Plinius SA Reference amp, it sounded thin, the TUNAMI GPX-R V2 sounded good on that same amp.
I'm sure some others will chime in, and be able to better assist you with your decission.
