Thanks @audphile1. Your post is surely useful. I’ll surely wait for it. As the TCS31 / FI-28 (R) already showed a glimpse of brilliance on good days, I’m sure it would sound fantastic once it’s all over.
Currently I do not have any requirements for additional power cords but the DPS4.1 / FI-50 (R) NCF will surely be at the top of the list when the need for one arises. It’s a premium price to pay but good to know that the clarity, extension and purity of tone are all excellent with the cable. Also, useful to know the S55N comes close to the DPS4.1 at a fraction of the cost. I prefer the color of the S55N to DPS4.1 though.
Looking at most responses here, one thing is for sure. Although the costlier DPS4.1 / FI-50 NCF is undoubtedly better, the cheaper options (FP-S032N, FP-S55N, TCS-31 with FI-28(R) etc.) are still excellent and not severely outclassed. Will see if I can allocate a small fortune for the DPS4.1 / FI-50 (R) NCF perhaps sometime next year or when I have the itch, and then call it a day when it's all done. 😁
