I've got Furutech mains cables throughout my system now and found that each and every one I added, improved the sound of my system. I tried an array of different plugs along the way, but have settled on Furutech again. My cables include S022N and S032N from the FP-S Alpha Nano series, and the often overlooked (and underrated) FP-3TS762 from the Alpha series. This is a cable intended for high current applications really which has very thick and stiff connectors, it certainly takes some time to terminate it well. I used these on my active speakers and the difference over some Lapp cable I was using before that was pretty massive tbh, I was taken aback as the Lapp was a substantial improvement over the manufacturer cables.
I've listened to the TC-S series too but personally found them a little too smooth and polite in my system. Never tried the DPS4.1 incase I loved it
There does seem to be a similarity in sound between the ranges (as you may expect), so it's worth trying all (both?) to see which works best for you.
Plugs wise, the Fi-28 represents great value but I have a number of Fi-11 too on components I don't use so much. Never tried a Fi-50, again incase I liked it. The Fi-1363UK mains plugs are excellent, easy to wire up even with stiff/thick cables and improved the sound for sure. I did like the MS HD plugs too and if you can't accommodate the Furutechs from a space point of view, they're a very close second (I compared gold and Rhodium versions - Furutech better sounding in both cases, but not by much tbf).
Plating of plugs does make a difference too, but I found less so than some others have found. Rhodium at both ends was a little less laid back than I like, Gold at both ends is maybe a fraction too laid back but a mix of one of each tends to give me what I'm after, smooth but detailed.
From what I've experienced, I would say the following things:
1) Make sure you try them in your system (advice is great, but no substitute for listening in your own system)
2) Buy the right cable for the application (don't assume that the top of the range, super thick cables are always the best. Some components don't seem to need it)
3) Plating and length of cable make less of a difference than the type of cable and connectors. You can almost fine tune the cable with these two aspects (once you know what you like).
4) Don't make a snap decision. I've found that mains cables take a good long while of use to sound their best, so give them plenty of time before you start making judgements (3-5days of use depending on core thickness in my experience)
It's your money at the end of the day, so it's whatever you like and think is right for your system (and wallet!). I would maybe start with an FP-S022N, Fi-1363G and Fi-11R or Fi-28R, and see how you get on. This is a fantastic value cable and is also a great test bed for trying other connectors/platings etc.
