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.
