Oyaide or Furutech plugs

Thank you for your answers.
No problem for me if the plugs are difficult to use, I won't build the cable myself, I'll pay a professional to do so.
Great, I'll go with the FI-28 and FI-38 (G) since they are less expensive than the Oyaide plugs.

Well, actually I now have some hesitation about the cable, between the FP-TCS31 and the older FP-3TS762, which is described as very good for big amplifiers.
Do you have some recommandations/preferences between these two cables? Price does not matter.
I'm searching for the smoothest and creamiest possible cable, with no rise in the high medium or treble and which won't be too thin in the bass department.

Don't want to steer you away from the Furutech if you're set on it, but I've had good DIY results on tube/hybrid power amp with Acrolink 7N P4030II. 
https://www.ebay.com/itm/ACROLINK-7N-P4030II-Stressfree-Power-Cable-Sold-By-1Meter-Each-Cut-100-Genu... Very smooth and detailed, with good bass.  And 7N P4020III on all things digital.  Oyaide connectors (I'm using P/C-004) are a bit pricey, but are rock solid.

I'd choose Oyaide. There's a lot of evidence that suggests Furutech is actually a Taiwanese company rather than Japanese, with a lot of their products being made in Taiwan. 

I like Furutech because pure copper is used as opposed to berillium copper used by Oyaide.  VH Audio has a lot of info about plugs and other components used by audio people.

+1 VH Audio, Chris just made me a Furutech FP-S032N with F1-11 gold connectors and it sounds fantastic. He was extremely helpful answering questions as well. Furutech makes great products I could care less if they are from Japan or Taiwan thought I've seen no evidence of the latter.
